My Favorite Apps for Portable Operating

I do the majority of my HF operating while out at portable locations. Like most people these days, I always have my cell phone handy. While I have a bunch of apps installed, there are a few that I use most often to figure out where to go and where I am.

Before I begin, I should mention that I use an Android phone. Some of these apps may be available for the iPhone or there may be similar apps available for you.

I should also point out that I do most of my hiking and biking on well-established trails. Suburban Philadelphia is not exactly a wilderness area. Wilderness and backcountry folks will likely have different needs.

Having said all that, here are the non-ham-specific Android apps I use most often in the field.

Where Am I?

This appropriately-named app by Ejelta LLC does exactly what it says. Using your phone’s location services, it shows where you are in the world. It shows your city, zip code, phone area code, sunrise and sunset times, elevation, and GPS coordinates. It also identifies the county you’re in, which is useful for setting up a new location in the TQSL software for Logbook of the World (LoTW).

The sharing feature is also important to me. When I’m out alone, I use Where Am I? to text my location to my (far) better half. I can send her the location of where I parked my truck and where I stopped along the trail to play radio.

Maidenhead Grid Locator

Another piece of information I need for LoTW is the grid square I’m in. For years, I used (and still use) an app with the simple title, Locator. As I started writing this post, I found that this particular app is no longer available in Google Play. No worries; there are lots of other apps to determine your Maidenhead grid square. Here are a few:

  • Ham Locator (by OH5GQF) shows your grid square (6 characters) on a map. You can toggle between street view and satellite view.
  • If you use HamLog (from Pignology) for portable logging, check the “Tools” tab. There’s a grid locator tool there. You can navigate around a map to find the grid square anywhere on earth.
  • HamGPS (by EA4EOZ) is a grid locator on steroids. It shows your current grid square out to 10 characters, along with your coordinates and compass heading. It also shows the location and status of the GPS satellite constellation. That can be fascinating to watch.

TrailLink and AllTrails

These are two similar apps that I use for planning trips to new trails. The Rails to Trails Conservancy produces TrailLink, while AllTrails is from AllTrails, Inc. They both give you maps, directions, reviews, and more. Both apps have paid versions that will let you save maps to your phone. That’s handy if you are in an area with poor cellular coverage.

Storm Radar

Last but not least… There’s no shortage of weather apps for your phone. I have one that I use for the usual weather forecasts: daily, hourly, and so forth. I also use Storm Radar (The Weather Channel) and it has saved my bacon on a few occasions.

Of course, Storm Radar‘s radar display lets you see exactly what’s coming your way. What I really like, though, is the real-time rain and lightning alerts. Even if I don’t have the radar display up, Storm Radar gives me a heads up on nasty weather headed towards me. There have been times when this app helped keep me and my gear from getting rained on.

Wrap-Up

So these are some of my favorite apps for portable operating. I didn’t cover any apps that are specific to ham radio but I may do that in a future post.

Do you have any must-have apps for outdoor operating? Let me know in the comments.

Adjustable Bungee Cable Ties

This is another one of those little hacks that takes longer to describe than to build. Some time ago, I stumbled on a clever idea online that has been useful in my ham radio activities.

I used to use ball bungee fasteners in a variety of sizes as temporary fasteners. While they are handy, they have limitations for my uses. On occasion, I found that the sizes I had available were either too small or too large for the task at hand.

A year or two back, I found a great video on the MOD YouTube Channel. The video described how to make these simple, adjustable cable ties. I made up a few and found them handy for several ham-related applications.

These little devices have a multitude of uses but my main use is for antennas in the field. I use them to fasten a BALUN or UNUN to a telescopic pole for portable verticals.

I also found they are also handy for lashing odd items to the MOLLE loops on my backpack. In a recent post, I showed how I use them to secure a 19-foot telescopic pole to my sling pack.

I use one of the bungee ties to attach the 19-foot vertical matching box to the fiberglass pole.

Of course, they make great cable ties. Their ability to adjust allows them to fit a wide variety of cables.

You only need 2 things to make these: some shock cord and some double hole cord locks. (If you watched the MOD video, you already know all this.)

I use 4mm diameter shock cord most often to make these. For some smaller, light-duty applications, I have used a thinner 2.5mm shock cord. I have found that the cord locks seem to hold better with the larger 4mm shock cord.

Construction is super simple.

  • Cut the shock cord to the desired length. Be sure to singe the cut ends with a lighter to prevent fraying.
  • Put the two ends through the holes in the cord lock.
  • Holding the two ends together, tie a simple overhand knot and snug it down.
  • To use them, place the bungee around whatever you need to fasten. Place the loop end over the cord lock to hold it. Press the button on the cord lock and pull the ends to cinch it down.

That’s all there is to it. In the time it took to write and edit this post, I could have made a ton of these things. It’s not an Earth-shattering thing but sometimes it doesn’t take much to amuse me.

Thanks to MOD YouTube Channel for sharing this great idea.

Sling Pack for My QRP Stuff

My XYL has accused me of being obsessed with bags, backpacks, and storage containers of all sorts. She’s an excellent judge of character.  This one, fortunately, wasn’t very expensive.

A few years ago I bought a backpack with ham radio in mind. I wanted one big enough to carry my Alexloop antenna, along with my QRP rig, battery, and, assorted emergency and survival-type gear. (I could survive a zombie apocalypse with all the stuff I put in that pack.) Although it continues to serve me well, at 35 liters it’s a bit overkill when I don’t need to carry all that stuff. I wanted something a bit smaller and lighter for short hikes and casual outings.

After looking at a dizzying array of small packs, I settled on the Rambler sling pack from Red Rock Outdoor Gear. It’s a bit larger than most other sling packs but I needed one that would accommodate my essential radio gear. It measures about 10 inches x 16 inches x 4 inches and has lots of compartments and MOLLE webbing.

The main compartment comfortably accommodates the box that holds my KX3 and accessories. I also carry a LiFePO4 battery and my antenna wires in this compartment. I use one of the outer compartments to hold safety and comfort items, e.g., first aid kit, sunblock, insect repellent, emergency poncho, etc. In the remaining outer pocket, I keep a headlamp, emergency whistle, compass, a copy of my Amateur Radio license and a notepad and pencil. There’s a compartment on the back of the pack that’s perfect for carrying a folding sit pad and a large contractor garbage bag that I use as a ground cloth. With the water bottle pouch on the side of the pack, I don’t have to use up space inside the pack to carry water.

The Red Rock Sling Pack also does double-duty for public service events with my local ARES-RACES group. I just remove the QRP gear from the main compartment and replace it with my HTs, spare batteries, emergency vest, etc. Oh, did I mention snacks? Yeah, lots of snacks.

With all the MOLLE webbing on the pack, I couldn’t resist adding a few things. On the back of the pack, I added a pouch for my HT. I added a cell phone holder in the front on the shoulder strap. I use the webbing on one side of the pack to carry my telescopic fiberglass pole, which I fasten with some adjustable bungee cords. And just for the heck of it, I added some molle-compatible velcro strips for attaching a morale patch.

The small strap at the bottom of the picture helps to stabilize the pack but can be tucked away if not needed. My cell phone pouch is at the bottom of the shoulder strap.

The smaller waist strap at the bottom of the picture helps to stabilize the pack but can be tucked away if not needed. My cell phone pouch is at the bottom of the shoulder strap.

In use, I find it very comfortable. The padded strap is non-reversible and goes over my left shoulder. That’s my preference anyway. The zippers on this bag have all worked smoothly without a lick of trouble. (Nothing frustrates me more than balky zippers!)

After nine months of use, the sling pack is holding up well and has fit my needs exactly. It provides a handy and comfortable way of carrying my radio stuff out into the field. There certainly are more expensive packs available but, for less than $50.00 USD, the Red Rock Sling Pack has been money well spent.

Now, all I need is to find some time to get back out into the field for some QRP fun.
