Having reached the Centurion level (100 SKCC member QSOs) back in mid-March, I set my sights on reaching the Tribune level (50 QSOs with Centurion or higher members). Thanks to the many SKCC members who were eager to add me to their logs with my new “C” designation, I made great progress over the following 2 weeks.
So, by last Monday (March 28th), I needed just 3 more QSOs to reach the Tribune level. Despite some rough band conditions, it only took about 30 minutes to reach my goal. The QSO that put me over the top was a nice chat on 20 meters with Pablo KP4SJ in Puerto Rico. Pablo’s QSO helped me reach Tribune on the 2-month anniversary of my SKCC membership. It was especially gratifying doing it with 5 watts into my rainspout antenna. SKCC members, apparently, have very good ears!
Now begins the long climb towards the Senator level. That entails 350 more contacts with Centurion or higher members and 200 more contacts with Tribune or Senator level members. That, for sure, is going to take quite a while.
I made a number of 2-way QRP SKCC QSOs during the week, as well. I worked K8FAC in Ohio, NC4RT in North Carolina, N0HYD (portable) in Kansas, AH6AX in Maryland, and NF1U in Connecticut.
I’m hoping that “Life-in-General” settles down a bit next week and lets me get out for some portable operating.
On Good Friday, I found myself with a free afternoon. I decided to take advantage of the great Spring weather and make a spur-of-the-moment trip to activate the Hopewell Furnace National Historic Site (NS37). I hastily threw some equipment into my truck and headed out.
About 45 minutes later, I was on site and ready to get started. But first, I had to resolve some antenna issues. For some reason, my SWR was higher than normal and not very stable. I found a loose BNC connector on my 4:1 unun that I think was the culprit. I eventually managed to get things stabilized enough to operate. I was using my FT-817 at 5 watts into a 29.5-foot vertical wire antenna with two counterpoise wires. I operated all CW.
I couldn’t spot myself due to lack of a cell signal, so I just started calling, “CQ NPOTA.” After about 35 minutes with no takers, I was pretty close to packing up and heading home. Finally, I worked a Wisconsin station on 20 meters. I tuned down the band a bit and heard N4CD activating a park in Texas. I got him on the first call. So, at least, I was getting out to somewhere.
I moved down to 40 meters a worked stations in New York and Michigan. One of them must have spotted me because things picked up quickly after that. I spent the rest of my time on 40 meters and wound up with 30 contacts in the log (including 2 park-to-park QSOs) after an hour and forty-five minutes.
After I packed up, I stopped by the visitor center and chatted a bit with the park rangers. They were very welcoming and happy to have their park activated again. They were curious about how many contacts I made and how far I was able to get out. As I was leaving they thanked me for putting their park on the air.
I have some repair work to do on my antenna but it was a nice afternoon for an NPOTA activation.
Back in January, I decided I wanted to add a new facet to this hobby that I’ve enjoyed for more than 42 years now. I have always heard a lot of Straight Key Century Club (SKCC) activity on the bands and it sounded like fun. So, I signed up for an SKCC number, dusted off my trusty J-38 key and jumped into the fray.
More than 20 years had passed since I made the switch to paddles and Iambic Mode B keying. Needless to say, my straight key fist was very rusty. After some off-air practice, I heard NN9K near Chicago calling, “CQ SKCC,” on 30 meters one day. I grabbed the J-38 and a few minutes later, Peter had given me my first official SKCC contact.
A few days later, it was time for the February SKCC Weekend Sprintathon (WES). The monthly, weekend-long WES contests are like most other CW contests except they are friendlier and run at a slower pace. After a fun weekend operating on and off, I ended up with 38 more SKCC contacts in the log. One particular highlight was working Bert F6HKA on two bands with my meager 5 watts and rainspout antenna. (Full disclosure: Bert’s awesome station gets most of the credit for these contacts. He was louder than most stateside stations.) After my first WES, I was hooked.
Even though SKCC promotes the use of manual keying methods, i.e., straight key, bug, cootie key; they have some pretty sophisticated, computer-based tools that can help you reach the various award levels. There are a few SKCC-specific logging programs. I use AC2C’s SKCC Logger for logging during WES contests and keeping track of all of my SKCC contacts. The K3UK SKCC Sked Page is an online gathering place for members looking for contacts. Another slick tool is the SKCC Skimmer. This software tells me who is online on the Sked Page and which SKCC members have been spotted on the Reverse Beacon Network (RBN). Most importantly, it lets me know if they have SKCC numbers I need for award levels I’m pursuing.
The thing I like most about SKCC is the friendly attitude of the members. They are particularly helpful to newbies and will always slow down to match the sending speeds of slower operators. Many times, operators would recognize my new SKCC number and take the time to welcome me to the club — even during contest exchanges.
After a month and a half of general operating and two WES contests, I found myself with 99 SKCC contacts. I needed just one more to reach the SKCC Centurion level. With some sort of geomagnetic disturbance going on, I resorted to the SKCC Sked Page for help. Within minutes, there were several stations trying to work me to put me over the top. Werner, N8BB in Michigan, was finally able to get me there. I applied for my Centurion award and received it later that day. I’m now in the process of trying to work 50 Centurion, Tribune, or Senator level members for the Tribune level.
I’m pleased to report that my old straight key fist is back in shape and I have rediscovered the elegant simplicity of the straight key. Many thanks for the good folks who run the SKCC organization. It’s easy to see why the SKCC is one of the fastest growing clubs in ham radio.
Here’s a little hack that serves no real purpose. I’ll tell you about it anyway.
I recently built the T-Tone Code Practice Oscillator (CPO) kit from Morse Express. It’s a handy little addition to the shack for adjusting straight keys or testing keyers. After building it, I just adjusted the audio frequency for a pleasing tone. Most people would have just left it alone at that point. I’m not most people.
I started to do some thinking, which is a dangerous practice that can sometimes lead to unexpected consequences. I wondered how the frequency of CPO compared to the sidetone of my FT-817. There was no particular point to this mental exercise other than idle curiosity.
Now, I certainly could have keyed both the CPO and the FT-817 and done a comparison by ear. I could have just adjusted the CPO by ear to match the FT-817. But what fun would that be? I was curious about the exact audio frequency of the FT-817’s sidetone, so I opted to do some experimenting.
Having been playing guitar for more than 50 years, I have acquired a gadget or two over the years. One of those gadgets is a clip-on guitar tuner. I can clip this clever device on the headstock of my guitar and, by sensing vibrations, it will tell me what note I’m playing and whether the pitch is sharp or flat. I figured I could use this thing as an audio frequency meter of sorts.
First, I laid the guitar tuner on top of the FT-817’s speaker and keyed up. That indicated that the pitch of the sidetone was an F note. Consulting a conversion chart I found on the Internet, that equates to 699Hz. I seemed to recall that the FT-817’s sidetone was somewhere around 700Hz, so that seemed about right. I was sure I was in the right octave.
Next I took the lid off of the CPO and clipped the guitar tuner on it. It initially indicated that the CPO was tuned to F#. That equates to a frequency of 740Hz. I tweaked the CPO’s frequency adjustment pot to F, matching the FT-817. A side-by-side comparison of the CPO and the FT-817 showed that I was successful.
So, what’s the point of all this? None really. Is there a practical use for this? Probably not. Does it really matter that my CPO matches the sidetone of my radio? Nope. I just had one of those “I wonder what would happen if…” moments. Now I know.
As I mentioned in an earlier post, I bought the little American Morse MS2 straight key intending to somehow magnetically attach it to the clipboard I use for portable operating. It took some thinking but I came up with a workable solution. I might come up with a better solution in the future but, for now, it should suffice.
What I set out to do was build a wooden mount that could attach the MS2 that held two magnets that lined up with the steel washers on the clipboard. I had a couple of “super magnets” that I planned to use. The problem I ran into is that the magnets are almost too strong to attach directly to the washers. My solution was to enclose the magnets within the wood base.
I cut a 1×3.25-inch piece of 1/8-inch plywood. Then I drilled two 3/4-inch holes just deep enough to fit the magnets. After placing the magnets in the holes, I glued on a thin wood veneer. This puts some extra spacing between the magnets and the washers on the clipboard. After drilling a mounting hole for the MS2, I sprayed on a couple of coats of paint.
After letting the paint dry, I went to attach the key to the base. Oops! I drilled the mounting hole from the wrong side of the mount. My first inclination was to putty it in and repaint. However, I decided to leave it there as a constant reminder to always measure twice and drill once!
The mount actually works well. The concealed super magnets hold the key firmly to the clipboard without the need for excessive force to remove it. Once I free up some time, I’ll give it a thorough test out in the field.
Here’s a little battery pack I put together for use as an external, portable power source for my YouKits HB-1B. I wanted something relatively lightweight and inexpensive that would put out at least 13 volts. This solution has fit the bill, so far.
There isn’t too much to it. I already had some Li-Ion cells on hand, so I wanted to make use of them. They are 18650 cells with a 6000 maH rating. I haven’t actually verified the claimed capacity but most cells tend to be somewhat over-rated. These particular cells are the “protected” type; each cell contains some circuitry that prevents overcharge and over-discharge. There are much cheaper unprotected cells but I’d rather be safe than sorry.
To put it together, I bought a 4-cell battery holder for 18650-size cells. With 4 fully charged cells, the voltage can exceed 16 volts. To keep the voltage below 14 volts (the maximum for my HB-1B), I put 3 silicon diodes in series with the output. This brings the voltage down to about 13.7 volts with fully charged cells. I also added a 2-amp fuse and an Anderson Powerpole connector.
To package it, I had a sandwich-sized Rubbermaid container that wasn’t being used. It turned out to be the perfect size to hold everything snugly. When not in use, everything is neatly tucked inside the container. In use, I lift one corner of the lid to bring out the connector.
For charging, I remove the cells from the holder and charge them with a Nitecore D4 charger. This is a 4-bay smart charger. It automatically detects the type of battery inserted and applies the proper charging method. Each bay works independently, so balanced charging is not an issue. The D4 works with a variety of battery types (Ni-Cad, NiMH, Li-Ion, etc.) so it is a handy accessory in the shack.
I haven’t done any formal testing of this battery arrangement, but it has provided adequate power for an afternoon of portable operating. For extended operating sessions, I throw 4 extra cells in my backpack that I can swap in if needed.
It’s not the most elegant solution but it works fine.
For many years after I first learned the code in the Navy, I was a die-hard straight key user. Unfortunately, back in the 90s, I started to experience some wrist pain and switched to using iambic paddles. Recently, after working one of the Straight Key Century Club (SKCC) K3Y special event stations, I was inspired to sign up with SKCC and dust off my straight keys. Hopefully, I will be able to get my old straight key fist back in short order.
Since I do most of my operating while portable, I wanted a straight key that was easy to pack and use while sitting on the ground along some trail somewhere. I was looking for something small that I could add some magnets to for use with my little clipboard.
After doing some research, I decided on the American Morse MS2 miniature straight key. I built a set of Doug Hauff’s (W6AME) NorCal paddles from a kit many years ago and they are still in regular use. Doug’s machine shop produces some precision stuff.
The kit arrived a few days after I placed my order. Following the manual’s precautions, I emptied the parts into a baking pan. Some of the parts are pretty small and would disappear forever if dropped on the carpet. Even with my aging eyes, it only took about 45 minutes to assemble the kit. (A younger person with better eyes and steadier hands could have done it faster, I’m sure.) You need to supply your own cable and connector, so I dug an old audio patch cable out of my junk box and cut it in half.
The key is 2 inches long by 1 inch wide and is made from machine aluminum. The contact gap and spring tension are fully adjustable. The key (with my cable attached) only weighs about 2.7 ounces (76 grams).
After adjusting the contact spacing and the spring tension, I was surprised at how great this little key feels. The knob is a little different from most keys, but I was able to easily adapt to it. As expected, the overall quality of the key is outstanding.
My next project will be to attach some sort of base to it with magnets spaced to line up with the washers on the clipboard I use while portable. More on that in another post. I’m looking forward to making some SKCC contacts from out in the field.
