U.S. Navy Morse Code Training

The material below is from a training manual used by U.S. Navy enlisted personnel studying for advancement to the rates of Radioman 3rd Class and Radioman 2nd Class (E4 and E5, respectively). This edition, dated 1967, was still around in the early 1970s when I used it. While it may provide a nostalgic look back for former Navy radio operators, much of the material on technique may still be useful for today’s beginning amateur radio operators. Enjoy! — WB3GCK

Chapter 4
International Morse Code

The international Morse code is a telegraphic alphabet, with letters and numbers represented by sound patterns.

If you are a graduate of a Class A Radioman School, you were taught the Morse code, consequently much of this chapter may be of little interest to you. But, if this is your first acquaintance with the code – if you are striking for Radioman from the deck force, or changing to Radioman from another rating – you have many hours of hard work ahead. Do not be discouraged on this account. Many fine Radiomen learn the code for themselves.

The letters in Morse code are represented by dots and dashes; radio operators, however, substitute the expressions “dits” and “dahs,” which closely resemble the sounds of the telegraphic hand key. The groups of dits and dahs representing each letter must be made as one unit, with a clear break between each dit and each dah, and a much more distinct break between the letters. A dit is one-third the length of a dah.

You must never try to count the dits and dahs. Do not let yourself get in the habit of doing so. It is a temptation at first, but you won’t be able to count fast enough when the code speed picks up. Learn sound patterns instead. To understand what a sound pattern is, rap out the pattern beginning “Shave and a haircut.” You recognize this from its characteristic rhythm, not because it has a certain number of beats in it. You must learn the code the same way. There are 36 Morse sound patterns for the letters and numbers, plus a few others representing prosigns and punctuation marks. With study and drill you can learn to recognize each pattern as fast as you now recognize “Shave and a haircut.” The accent always falls on dahs, and you should pronounce each rhythmical combination with that emphasis in mind.

Go through the alphabet several times to get the sound “feel” of the dit and dah combinations.

MORSE ALPHABET

In the pronunciation guide for sounds of letters that follows, sounds are written as phonetically as possible. In the middle of a group, the short sound “dit” actually takes on the sound “di.” The phonetic alphabet is included in parentheses after the letters. Acquire the habit of referring to the letters phonetically.

STUDYING CODE

If you have any trouble learning Morse code, the following method may be helpful. Go through the three groupings of short, medium and long sounds with their accompanying practice words. Make up words of your own if you wish to give yourself further practice. Speak the practice words in code. Say “tee: DAH dit dit;” “mine: DAH-DAH di-dit DAH-dit dit.”

If you can speak words in code rapidly and distinctly, you will have an easier time when you learn to receive code on the receiver. The sounds are very similar.

You probably have noticed by now how numerals slow your speech in oral transmission. That is understandable – they also slow the speed of radio transmission. Headings containing procedure signs, calls, and numerals are transmitted at a slower rate of speed than straight alphabetical characters.

RECEIVING

If you have carried out the recommendations made up to this point, you are ready to receive code transmitted to you on an oscillator. The ship or station to which you are attached is almost certain to have practice oscillators for your use.

An experienced Radioman will key code groups to you for your training. The sound produced by an oscillator closely resembles the sound of code from the radio receiver. The operator keying to you for practice should transmit each individual character at the standard rate of 20 words per minute. He should maintain a fairly long interval between characters. As you progress, you gain speed by shortening spaces between characters.

The standard character speed is shown in figure 4-1. Note that the characters themselves may be keyed at 20 words per minute, but that the longer intervals between characters and words materially decrease the beginner’s overall speed. Note also that the code, compared against time in the 20-words-per-minute transmission, is in the proper form of having the dit as a unit. There is one unit between each element of a character, three units between each character, and seven units between each group or word.

Figure 4-1. Correct keying of Morse characters.

After learning the sound of each character at this rate of speed, it is not difficult to reduce the time between characters and to copy code at a much faster speed.

As you advance in rating, you will be required to increase your transmission and reception speed. If you learn the fundamentals well, it will be fairly easy for you to increase your speed. When copying code, if you miss a character, don’t stop to worry about it; get the next character and let the one missed go by. Be a competent operator. Make every transmission and every reception accurately. Do not place speed before accuracy.

PRINTING CLEARLY

Learn to print clearly and rapidly. The messages you handle are important, and someone must read what you have written without puzzling over it. Examine figure 4-2 and compare the printed letters with your own. Notice that the sequence of strokes for some letters may be different from the way you customarily form them. As an aid to rapid printing, the more of the letter you can form with a single stroke, the better. Use this illustration as a guide to avoid confusions between printed letters and printed numerals. Especially watch the letter Z and the numeral 2. If you wish, write Z with a line through the stem (-Z). Even more important is the distinction between the capital letter O and the figure zero. In communication work, zero is always written with a slant through it (Ø). Exercise care to avoid confusion between letter I and figure 1, and also letter S and figure 5.

Figure 4-2. How to form printed characters.

As your code speed increases, you will find it impossible to print rapidly enough to keep up; therefore, typewriting is a skill also required of all Radiomen. Use of a good commercial text can help you master touch-typing. A typing course for beginners also is offered by USAFI.

SENDING

Your ability to send well depends mainly upon two capabilities. First, you must know the correct sound of the character you are attempting to transmit. Second, you must know the proper method for keying with perfect control. Practicing the code aloud, as well as receiving it by oscillator, has given you a good knowledge of code sound. The proper method for keying is your next concern.

HAND KEY

The first key you will use is the hand key. The hand key is widely used on radiotelegraph circuits and with practice oscillators. It must be adjusted properly before you can send clearcut characters. Figure 4-3 shows a hand key, with parts labeled.

Figure 4-3. Hand key.

KEY ADJUSTMENT

The spring tension screw, behind the key button, controls the amount of upward tension on the key. The tension desired varies with operators. Too much tension forces the key button up before the dahs are completely formed; spacing between characters is irregular, and dits are not clearly defined. If the spring tension is very weak, characters run together and the space between characters is too short.

The gap between the contacts, regulated by the space adjusting screw at the back of the key, should be set at one-sixteenth inch for beginners. This measurement does not apply to every key and operator; it is a matter of personal preference. Some operators like a closed key, others an open key. “Closed” and “open” are terms for a short and a long gap. As the student progresses, further gap adjustment may be made to suit his sending speed. Contacts that are too close have an effect similar to weak spring tension. Contacts that are spaced too far have the same effect as too much spring tension.

The final adjustment of the key is the sidewise alignment of the contact points. This alignment is controlled by the trunnion screws at either side of the key. If they are too tight, the key lever binds. If they are too loose, the contacts have sidewise play. Usually, when the sidewise alignment is correct, no further adjustment is required.

POSITION OF HAND ON KEY;
WRIST MOVEMENT

Learn from the beginning the correct way to grasp the key. Do not hold the key tightly, but let your fingers rest lightly on the key knob. Your thumb rests against the side, your forefinger rests on top of the key, your other fingers are bent slightly in a relaxed position. Check figures 4-4 and 4-5 for the correct method of keying. To ensure correct movement of your wrist and forearm, your arm should lie on the operating desk. The muscle of your forearm – not your elbow – should support the weight of your arm. Your elbow should not extend over the edge of the table, because the pressure of the underside of your forearm will partly block circulation and tire you. Sit upright, with your arm in line with the key.

Figure 4-4. Grasping the key. Figure 4-5. Your thumb rests against the side.

Your ability to transmit depends to a great extent on acquiring the proper movements of your wrist and hand while operating the key. To close the key, your wrist moves upward and your hand rocks downward toward your fingertips. To open the key, these two movements are reversed- your wrist comes down and your hand rocks back.

Make your wrist flexible. Limber it up. Correct wrist action may be developed by moving your wrist up and down like a hinge. Another exercise is rotating your hand in clockwise circles, with your wrist held in a stationary position. These exercises will relieve any undue tension you may experience when first beginning to transmit.

SEMIAUTOMATIC KEY

The semiautomatic key, also known as the bug or speed key, is used chiefly when operators are required to send for relatively long periods of time. It is designed to make sending easy instead of fast. Hence, perfect control of the key is far more important than speed.

OPERATION

In sending with the bug, the thumb presses the dit paddle (fig. 4-6) to the right, and the index finger forms dahs by pressing the knob to the left. The key sends successive dits when the paddle is held to the right. One dit or a series may be sent, depending on how long the thumb pressure is maintained against the paddle. One dah is formed every time the knob is pressed to the left. Dahs must be sent individually. While sending, the hand pivots at the wrist; the hand and arm motion is horizontal.

Figure 4-6. Semiautomatic key.

KEY ADJUSTMENT

Best operation of the semiautomatic key is obtained when it is adjusted to send dits and spaces of equal length. Adjust the key as follows, locating the parts in figure 4-6 when adjusting the key:

  1. Adjust the back stop screw until the reed lightly touches the deadener. Tighten the locknut.
  2. Adjust the front stop screw until the separation between the end of the screw and the reed is approximately .015 inch. Tighten the locknut.
  3. Operate the dit paddle to the right. Hold the lever in this position and stop the vibration of the reed. Adjust the dit contact adjusting screw until the dit contacts barely touch. Tighten the locknut. This adjustment determines whether the dits will be too heavy, too light, or perfect. The adjustment must be made without flexing the contact spring.
  4. If the dits are too fast, move the weights, located on the reed, in the direction of the deadener. If the dits are too slow, move the same weights in the opposite direction.
  5. Adjust the dah contact adjusting screw to a clearance of approximately .030 inch.
  6. Adjust the dit refractive and dah tension springs for the most comfortable, operation.

If the adjustment instructions are followed carefully, the bug makes 25 or more dits before stopping. The first 12 to 15 dits will be practically perfect, with the dits and spaces equal.

SENDING EXERCISES

Good operators have sending rhythm, and you can acquire it in just one way: by practice.

It may be difficult for you to key correctly at first, because your wrist is unfamiliar with the type of movement required for sending telegraphic code. Your wrist will be stiff, and you’ll have to get rid of that stiffness by a lot of practice. Don’t favor the stiffness of your wrist. If you do, your sending will be choppy.

The following exercises have been prepared carefully. Use them as an instruction guide.

  • Character E: The dit characters require a “goodfist.” They must be transmitted quickly and rhythmically. Make a series of Es (dits). They are made with a pronounced movement of your wrist upward, returning to the normal position after each dit. At first, maintain a fairly long interval between dits. To assist you in limbering your wrist, exaggerate the movement upward. To prevent tenseness and tiredness of your wrist, remove your hand from the key periodically and flex your wrist. After practicing Es for 15 or 20 minutes, decrease the interval between dits until you are making them rather rapidly. Each sound should continue to be a definite dit, however. Keep at it until you can control each dit.
  • Character I: When you feel that your wrist is limbering up, make the character I (di-dit). Start with your wrist in the normal relaxed position, raise it for the first dit, lower it quickly halfway back, and make the second dit with another quick movement of your wrist upward. Your transmission, made slowly, produces the sound di-dit. As you practice and develop more rhythm, this character acquires the sound of di-dit.
  • Character T: Send a series of Ts (DAH) with a good interval between them. Instead of a quick movement of your wrist upward, make aslower, more definite movement of your wrist and exert more pressure on the key. Send dahs for a few minutes, gradually shortening the interval between characters.
  • Character M: Now try sending strings of Ms (DAH-DAH). As with the character 1, you don’t return your wrist to the beginning position at the end of the first dah, but bring it to the halfway point and then make the last dah. With practice, you’ll soon change the hesitant DAH DAH sound to the snappy DAH-DAH. Don’t forget the correct wrist movements. If you find that your sending requires exertion of forearm muscles or that your shoulder is moving, stop and recheck your wrist motions.

Try these practice groups several times, backward and forward. Make them clearly and distinctly, spending more time on characters that cause you any trouble.

MEET EMIT MITE ITEM

  • Character A: The character A (di-DAH) gives you practice in making a dit and a dah together. Sending motions, in their proper order, are (1) slight pressure of your fingers alongside the key, (2) a quick surge upward of your wrist, (3) a slight relaxing of your wrist to the halfway point, and (4) a final definite upward movement of your wrist. This technique produces the sound dit DAH when you begin to practice it. But keep at it-you’ll soon have the proper di-DAH sound. Avoid tenseness; relax your forearm muscles when sending.
  • Character U: You’re now ready for the character U (di-di-DAH). Start slowly, sending dit dit DAH. Practice it until you get a di-di- DAH sound.
  • Character N: The character N (DAH-dit) requires only slight pressure on the sides of the key, a strong wrist movement upward, a half return, and a quick, short, upward motion for the dit. Practice for several minutes until you are able to send DAH-dit easily and with com- plete relaxation.
  • Character D, Try the letter D (DAH-di-dit). At first, with the correct wrist movement it will be DAH dit dit. But the sound you want to hear is DAH-di-dit-with a swing. Send Ds until you can transmit them with perfect control. Check yourself on the following groups. You should have less difficulty than you did with the first groups.

  • MINED UNITED READY MAUDE TEAMED

  • Character S: Go back to the dits for S (di-di-dit). Get a good position on the key and put your wrist to work. See how quickly you can change the dit dit dit sound to di-di-dit. Relax your forearm.
  • Character V: The letter V is di-di-di-DAH, so you’d better learn how to send it that way. Relax. If your wrist is tied up in a knot, you’ll be sending dit dit dit DAH. Move your wrist up and down easily until you are sending di-di-di-DAH with perfect control. Practice this letter carefully. It is used in every radio test.
  • Character 0: Correctly sent, characters is DAH-DAH-DAH. Keep at it until it stops sounding like three Ts. Test your skill with these words:


DOOM MOST ROAD MOTOR WORST MOTION WOKE ANCHOR DOMO

  • Character H. Character His di-di-di-dit. Send one. If it sounds similar to four Es, your wrist is too stiff. Develop the di-di-di-dit sound.
  • Character B: Send DAH-di-di-dit. It is the Morse code equivalent of B. Practice for perfect control, then try these groups:

  • SOB BASSINET BIND BESTED BEAUTY SNOB BABBITT BURST

  • Character K: At this point you should be prepared to tackle the other characters. They are mostly combinations of the letters you have practiced. Each one has a distinct overall sound. For instance, K should not have the sound DAH-dit-DAH. It should be DAH-di-DAH. Think of the tune “Over There.” You will realize that DAH-di-DAH has the same rhythm as OH-ver THERE-DAH-di-DAH.
  • Character Q: The letter Q (DAH-DAH-di-DAH) has the same rhythm as the words “Payday today.” Say in a monotone “payday today,” then say DAH-DAH-di-DAH. When transmitted, the same swing is given these combinations as when speaking or chanting them.
  • Remaining letters and numerals: The preceding l5 characters have taught you proper wrist movement. You know the remaining 11 letters and 10 figures. Following are 14 practice exercises. Use these exercises for self-drill.

PRACTICE MAKES PERFECT

Continue sending to yourself with the practice key and oscillator. If you can operate with another striker, so much the better. Sit down at an unused operating position and tune in some slow code. It is not hard to find, especially on amateur frequencies. Copy as best you can. Don’t worry too much about missing letters. Get what you can, no matter how little it is. As your speed picks up, tune in faster code. If you find you are copying a certain speed solidly, the code is too slow. Keep it faster than you can copy comfortably.

You will need lots of practice. Class A Radioman Schools ashore run a full day, and for months a man copies code several hours daily. Make the transition from pencil copying to the typewriter as soon as possible.

As you gain skill, try copying the 18-wpm to 20-wpm fleet broadcasts. Devote as much time as possible-15 or 20 hours per week-not just an hour now and then. Do not be afraid to use some of your off-duty time. Simultaneously, begin to learn how to hold down a circuit. One of the best ways to do this is to spend several watches logging circuits that other operators are manning. At the end of every watch, compare your log with that of the regular operator, and question him about anything you do not understand. That way you see procedure in use and gain practice in copying many fists.

Learn to copy behind. If you are recording B as D, S as I, J as W, and so on, you are copying too close. The farther behind the better. At first, listen to one character while setting down the previous one. Try to fall back one letter more. Listen for the character while carrying one in your head and setting down the one before that. Once you have the knack, you will find copying behind is easier, faster, and more accurate. The faster the code, the farther, you must stay behind. Watch an oldtimer copy press at 35 or 40 wpm. You will find he is carrying anywhere from 5 words to a sentence in his head.

One further word of advice: It is common for a student learning code to hit a plateau. The regular progress to higher speeds stops, and for a time the student finds himself unable to copy faster than a certain speed. If this happens to you, just stay with it until your speed picks up. Never lose confidence in the knowledge that any man of ordinary ability can learn the code if he puts in the necessary time and work

25 Years of QRP-Portable

My (far) better half was going through some old pictures recently and came across some pictures of me operating while tent camping on a family vacation back in August 1993. After I studied the picture for a bit, it dawned on me that the old photograph had captured my first time operating QRP-portable.

Back in the early ’90s, I was just getting back on the air again after a long period of inactivity. I had a station at the house but what I really wanted was a portable QRP rig. I eventually purchased an MFJ-9030 QRP rig for 30M so I could take my hobby on the road.

Right around that time, we were getting ready to take a week-long vacation of tent camping on the Eastern Shore of Virginia. Wanting to take my new rig along, I hurriedly went about assembling a portable station. I bought a gel cell battery from a local hobby shop and threw together a 30M dipole. I wasn’t sure how much coax I would need so I used 50-feet of RG-8x, which, in hindsight, was overkill. Together with my old Radio Shack straight key, I packed everything in a small, waterproof container and placed it with the rest of the camping gear.

Being the detailed planner and organizer that she is, it took my wife no time at all to spot my container of radio gear. This prompted a stern reminder that this was a family vacation and no way was I going to spend all day on the radio and leave her to deal with the kids. Despite my assurances that I wouldn’t do that, she remained skeptical.

The day after we arrived and got our camp set up, I went about putting up my dipole. Because of the dense pine trees, my dipole only ended up about 15 feet up. I had to coil up the majority of my 50-foot coax at the base of a tree. Yep, my fifty feet of coax was definitely too long. (It was replaced with 30 feet of RG-174 when I got home.)

My log shows that I made my first-ever QRP-portable contact on August 15th with K3EEL (SK) up in northern Pennsylvania. I made 3 more QSOs before calling it a day. I only operated for about an hour but I was hooked!

I’m an early riser. The rest of my family… not so much. So, for the rest of the week, I fell into a routine of getting on the radio early in the morning, while the coffee was brewing on the camp stove. I usually got on again later in the afternoon while the kids were relaxing before dinner. My better half soon realized that my ham radio habit could peacefully coexist with the rest of the family’s activities. In fact, one lazy afternoon she said, “Why don’t you get on the radio for a while?”

I had a lot of fun that week, making 34 contacts. Since then, a QRP rig has gone along on every camping trip or vacation we have taken.

Here’s to the next 25 years of QRP-portable operating!

Of Blind Squirrels and QRP Contests

There’s an old saying that goes: “Even a blind squirrel finds a nut once in a while.” I think that was the case for me 23 years ago.

As I was submitting my meager entry for last week’s QRP to the Field (QTTF) Contest, it made me think back to the very first QTTF contest in April of 1995. I’ve never considered myself a serious contester; not by a long stretch. Somehow, though, I actually placed 1st overall in the NorCal QRP Club’s inaugural QTTF.  I actually did it with a most unlikely setup, too.

A local ham, Rolf N3LA (SK), graciously allowed me to operate my modest QRP station from his rural property. I operated from my truck with my antenna supported by one of Rolf’s trees.

My antenna was simply a 40M inverted vee that I made from #22 stranded hook-up wire. I fed it with about 30-feet of RG-174 coax. The center of the antenna was only about 12 to 15 feet high. One end was tied off to a bush about 4 feet off the ground. The other end ran into a fenced-in area that was home to a ram with a bad attitude.  I had to wait until the ram was otherwise pre-occupied to tie-off that end of the antenna. That end was only a foot or two off the ground.

My rig was a Small Wonder Labs SW-40 running 950mW. This was from the first batch of kits offered by Dave Benson’s (K3SWL) former company. I was also using a keyer built from an old NorCal kit, which used the classic Curtis keyer chip. I used a set of paddles that I had cobbled together from stuff in my junk box. The whole station was powered by a 7 A-H gel cell battery that was almost as big as the rest of the equipment combined.

Some of the equipment I used for the QTTF Contest in 1995. The SW-40 and NorCal Keyer are packaged in LMB enclosures. My "Junkbox Paddles" are on the right. I made a lot of QSOs with this setup in years past.

Over the course the afternoon, I worked a steady stream of QRPers. I was in QRP heaven. Even Rolf, who was monitoring from inside his house, was amazed at the number of contacts I was producing with less than a watt.

I specifically remember a couple of the contacts.  I worked Joe N2CX, who was testing a new antenna over in New Jersey.  Joe later mentioned that QSO in an article about his antenna in QRP Quarterly. I also remember working Ernie W8MVN (SK) in Ohio. Back in the day, Ernie ran a pair of phased, full-wave 40M delta loops on top of a 60-foot tower. He called me with an ear-splitting QRP signal that had me scrambling for the RF gain control on my rig. I think my ears are still ringing from his incredibly loud signal.

Even though I only operated on one band with my 950mW rig, I managed to log 46 contacts (plus a few dupes) that day. With my QRPp multiplier, I ended up in first place out of a field of 50 stations.

I haven’t done that well in a QRP field contest since.  (I did, however, place 2nd in the New England QRP Club’s QRP Afield contest using the same equipment later that year.) Rather than skill or prowess as a contester, I have always attributed my win to a combination of great propagation and lots of plain old dumb luck.

If your callsign is in the log above, thank you for helping this blind squirrel find a nut!

Ron Polityka WB3AAL (SK)

I heard the sad news this morning that Ron Polityka WB3AAL passed away on March 30th. Ron was an avid QRPer who was well-known throughout the QRP community. Ron was known for his portable operations, particularly from the Appalachian Trail.

Ron and I go back about 25 years or so. Back in the early 90s, I was contacted by Ron, who was starting up the Eastern Pennsylvania QRP Club. My first meeting with Ron was at a local hamfest and I became an active EPA-QRP member after that.

Over the years, I participated in many EPA-QRP Field Days with Ron. I also camped out with Ron a few times for various QRP field contests. I spent an interesting weekend with Ron aboard the Lightship Chesapeake (LV-116) in Baltimore’s Inner Harbor in 2003. We activated the Chesapeake for a Lighthouse/Lightship Week event.

Ron was one of the founding members of the Polar Bear QRP Club. I was fortunate enough to take part in one of the very early Polar Bear Moonlight Madness Events with Ron and others at Pulpit Rock on the Appalachian Trail.

In recent years, I only had occasional contact with Ron. So, I was stunned to learn of his passing at the young age of 58. Ron touched the lives of many in the QRP Community and his presence will be missed.

RIP and 72, Ron.

A Memorable Contact

I’m sure we’ve all had memorable contacts.  You know, the ones where you can recall the content and the events surrounding them, even decades later.  I was going through one of my old logbooks today and I saw an entry from almost 22 years ago that brought back a flood of memories.

Back in August of 1995, my wife and I took our two daughters on a weeklong tent camping trip to the Eastern Shore of Virginia.  My wife had a “milestone birthday” that week (I won’t say which one) and that’s how she wanted to spend it.

We arrived at our campsite on Saturday, August 12th, 1995, and quickly set up our tents.  As is my usual custom, I brought a QRP rig along.  My simple set up for this trip was my old MFJ-9030 30M rig and my old J-38 straight key.  I strung a lightweight dipole between two pine trees and ran the RG-174 coax down to a picnic table.  The rig was powered by a 7 A-H gel cell battery, which was enough power for a week of casual operating.  The MFJ-9030 put out about 3 watts under battery power.  On a typical day, I got on the radio each morning for a couple of contacts and again later in the day.

Our vacation got off to a great start.  While my wife was away from the campsite on her birthday, the girls and I threw her a surprise birthday celebration.  We decorated the campsite with balloons and streamers.  My family enjoyed spending time outdoors without the distraction of TV and telephones.  Back in 1995, smartphones weren’t available and I didn’t own a cellphone yet.  By Monday, there weren’t any other campers near us.  So, we were blissfully unaware of what was going on in the world outside of our little campsite.

The morning of Tuesday, August 15th, 1995, was a typical morning for me while camping.  I was up earlier than the rest of the family.  I got the percolator ready and fired up our old Coleman camp stove.  While the coffee was brewing, I turned on the radio and tuned around the 30-meter band.

Just before 7:00 AM local time, I made contact with Clark W8IHN/8.  Clark was operating portable from Houghton Lake, Michigan.  We had a very nice rag chew.  During our CW conversation, Clark mentioned that he was 79 years old and had been on CW for 66 years!  He was interested in our camping set up and our location.  He asked me if I was following the news.  I said I hadn’t been.  He said I should since there was a hurricane heading our way.  He said it looked like the Virginia coast was going to be getting high winds and “big surf.”  He advised that we not wait too long to leave the area.  We signed off after an enjoyable 45-minute chat.  In my notebook, I wrote, “QSL for sure.  Send a postcard.”

QSL card from W8IHN. On the back of the card, he wrote: “What can I say, Craig, it’s not often that I run into a fellow ham that I take a liking to. I do hope we can meet up again on 30M.”

Concerned by Clark’s warning, I got in the car and tuned the radio to a local broadcast station. Clark was right — Hurricane Felix was heading our way.  Before we left Pennsylvania, Felix was still churning around in the Caribbean.  It didn’t seem to be much of a threat to our vacation plans.  Now, a hurricane warning, which included our location near the lower Chesapeake Bay, had been issued.  To the south of us, they were planning an evacuation of the Outer Banks of North Carolina.  Things were getting serious.

We spent the day listening to the news on the car radio and considering our options.  I suggested that we head inland and look for a safer campsite.  In the end, we decided to just head home the next day.

The next morning, I made two last contacts on 30 meters before taking the dipole down.  After breakfast, we tore down the tents and packed up for the trip back to Pennsylvania.  We stopped in the campground office to check out.  They said they were planning to evacuate the campground later that day.  Since they were planning to close the campground, they gave us a credit for our unused nights.

We were all disappointed that our vacation was cut short.  At least, we able to get out of the area, avoiding the traffic and confusion of an evacuation.  As we drove home, I was glad that I brought the QRP rig along and very grateful for that CW contact with W8IHN that had tipped us off to the bad weather heading our way.

In the end, Felix never did make landfall in the U.S.  It did, however, impact the East Coast.  In addition to major beach erosion,  nine unfortunate souls lost their lives due to the heavy surf.

Clark and I exchanged QSL cards but I don’t think I ever worked him again after that.  His real name was Whittier E. Clark.  Doing some Internet research, I found out that he became a Silent Key two years after our contact.

Wherever you are, Mr. Clark, I still think about our CW contact in the summer of 1995 and the concern you showed for me and my family.

Ham-iversary

For a variety of reasons, the past week has been a slow one for me, radio-wise.  However, I did notice on my calendar this morning that today is the 42nd anniversary of my first ham radio license.  Wow!  Where has the time gone?

Forty-two years ago, I had finished up my 4-year enlistment as a Navy Radioman and had just started school studying electronics.  I had plans to get my ham license, so I began to blow the dust off of my rusty CW fist.  Although the Navy trained me in Morse code, I never really had many opportunities to use it.  Also, I had never copied code without a typewriter (or “mill” as we called them in the Navy) so I had to learn how to copy CW with pencil and paper.

Once my code was back up to snuff, I contacted a local ham, Bob Rothrock K3MAZ (SK).  Years earlier, he restored an old console radio that my grandmother had given me.  Bob was the only ham I knew at the time and he graciously administered my Novice exam and helped Elmer me along when I had questions.

After receiving the callsign, WN3YSV, it took several months to put a station together and get on the air.  I found a used Heathkit DX-60 transmitter and paired it up with a Realistic DX-60B shortwave receiver I already had.  Anxious to get on the air, I quickly threw together a low dipole for 15 meters.  I picked 15 meters only because the dipole would fit easily across the backyard.

When I finally got on the air, I nervously called CQ a few times and was answered by K3RDT.  I was excited to hear someone calling me and I’m sure my sending reflected my nervousness.  I had never had a conversational CW exchange before.  As it turns out, Pete was only about a mile away from.  He helped other novices get on the air and seemed happy to be my first contact.

A few days after that shaky QSO, I received my first QSL card.  On the card Pete questioned my choice of 15 meters and encouraged me to figure  some way to get on 40 meters.  Of course, he was right.  I eventually rigged up a 40-meter dipole and ran across the roof of the house and across the backyard.  Although I made some nice contacts on 15 meters, the 40-meter novice band was where the action was for me.  I also became interested in QRP early on.  I built a little one-watt transmitter during that time and made a few contacts with it.

After a little over a year of operating, I moved away to start a new job.  My ham radio gear got packed away and I focused on my career and raising a family.  It would be another 15 years before I got back on the air with my current callsign.  Ham radio was definitely better the second time around.

Even after all these years, the thrill has never subsided.  This radio stuff is still like magic to me.
