My Ideal POTA Kit!
2022-04-14 Yesterday was in the 40's with wind gusts of 50 mph, no POTA! So I decided to add 40 meters to my 20 meter pedestrian mobile antenna. It is one I made for my QRPGUYS DS-1 but works well on this one. My 20 meter coil has taps for other bands so I checked out the tap for 17 meters which seemed to tune OK. If it warms up a bit today I may check out the other taps as well. Should be fun when activating next time. I may just end up with a versatile antenna!
2022-04-14 My concept of "ideal" when it comes to a POTA kit is changing, perhaps broadening since playing with pedestrian mobile! See my Pedestrian Mobile A Reasonable Option page. The idea of strapping your whole station, including the antenna on your back and (and/or front) introduces whole new requirements compared with a kit designed to transport a semi-fixed station to an operating site. When pedestrian mobile, your body is the operating site! Most if not all of the ingredients or items required are the same, but how they are deployed is considerably different. And that has significant implications for "the kit."
I'm just beginning to think about how gear should be packed to transport it to "the jumping off point" for a pedestrian mobile activation. So far I've just tossed it in the car and taken off! but as I think about taking it on trips to visit family or maybe even fly to a location, that needs more thought and planning. Always something to think about with ham radio!
2022-03-10 The latest update to my POTA kit is the Ed Fong DBJ-2 Ham Portable Dual Band J-pole antenna. It is a very light weight 2m/70cm j-pole designed to be suspended from a tree branch or other support for portable operation. I've just had it a day but took it to K-4265 this afternoon to try it out. It was a brief test but I came home with my first two meter activation contact and learned a few things in the process.
2022-01-28 I'm zeroing in on the radio and antenna kit for the trip to Tucson, AZ the end of February for activating Saguaro National Park. I'm sure I'll make some changes before then but the gear in the photo to the right will likely be the core of the final package.
At the top is the bag I'll be carrying everything in. The three items immediately below the bag are 1) 10 meter (33 ft) of RG316 coax, 2) the K6ARK 29 ft end fed with a 17 ft counterpoise and 9:1 unun (green wire), 3) the KM4ACK 40 meter EFHW with alligator clip links for 30 and 17 meters (orange winder).
In the center is the ICOM IC-705 transceiver. I have the 3800 mAhr battery on the back. Immediately below the IC-705 is a 5v wallwart and micro usb cable for charging the IC-705.
To the left of the radio is a short RG174 patch cable, Elecraft T1 antenna tuner and extra battery. The T1 tunes the 29' antenna on almost all bands which makes it a very flexible antenna.
Across the bottom are my logging clipboard, pencil and CWMORSe US paddle and cable. On the left is a 15 ft length of 1/8 inch bungee cord which is very useful for tying off the antenna to almost anything! Not pictured is the microphone.
Finally, on the right side is my 15 ft carbon mast (fishing pole). It will support the EFHW as an inverted VEE or the 29' end fed as a sloper. Not pictured is my pre-bundled tree cord guy rope kit so I can erect the mast using just three tent pegs.
I do often also take along a spare paddle and cable and a 25 ft rg316 coax, a 25 ft or so small cord or rope as well as my NanoVNA in a separate bag. I might even include a 4.5Ah or 6 Ah 12 volt LIFEPO4 external battery and cable to give me the 10 watt option in that separate bag. I'm sure I'll make some changes to this kit as time goes on, but for now, it does the job nicely and only weighs around 7 lbs.
2021-12-29a After what I wrote earlier today about my small POTA kit based on the Xiegu x5105 I decided to see if I could put together a similar kit based on my ICOM IC705. The ic705 wouldn't fit into that nice little case I have my x5105 in but I found another bag that was just right. My logging clipboard sits against the back of the main compartment. The radio fits nicely in the bottom of the main compartment on top of a folded Amazon shipping envelop. Another folded Amazon shipping envelop cushions and protects the top of the radio. Then a 33' RG316 coax, my QRPGuys 35' end fed antenna, the Elecraft T1 tuner and my CWMORSE paddle fit nicely on top of that. The microphone fits into the front pouch. Oh, a couple of mechanical pencils fit into the pencil pockets on the side! And the whole thing only weighs 5.1 lbs, just about a half pound more than the x5105 based kit. There is also room for a 4.5Ah Bioenno battery and cable in the top if you want the extra battery capacity. That brings the total weight to 6.5 lbs. The radio is limited to 5 watts output using only the internal battery but with an external battery it will put out 10 watts.
Not content to have it sitting on my bench, after lunch I quickly grabbed the bag, a bottle of water and a snack and headed to Park K-1440 near Lake Geneva, WI about twelve miles from home. I'm working on my POTA Kilo there! I left home about 12:50pm and I had to be back by 2:45pm at the latest. No time to waste! I arrived about 1:15pm. There was about two inches of snow on the ground and the temperature was 28 degrees, thankfully with little breeze. I operated from inside my car.
I set the rig up pretty much as I have been doing with my x5105 shown below, with the radio sitting on the door of the glove box. I quickly connected the RG316 coax to the radio and tossed it on the ground outside the passenger door. I had already set my DIY drive-on mast stand under the left rear tire with the 33' spiderbeams mast sitting in it so I quickly attached the far end of the antenna to the mast with some 1/8th inch bungee cord and cord locks and extended the mast. Then I finished unwinding the antenna out beyond the right front corner of the car where I secured it with another length of 1/8th inch bungee cord to a brick I had brought along. The unun was about six inches off the ground. Then I connected the coax.
Back in the car about 1:25 I finished connecting things out and tuning the antenna with the T1. 40 meters was crazy with a CWT contest, so I settled on 30m, selected 10.109, posted a spot on the POTA site and began calling CQ POTA. Had my first response at 1:31pm, W0SK in Tennessee. At 1:50, when I had to pack up, I had 13 stations in the log including one P2P in Idaho! Headed home at 2:15! Several people stopped by to ask what I was doing which was fun. Most had heard of ham radio but didn't know much about it. I was back home at 2:30, fifteen minutes ahead of schedule!
Observations? Everything worked very well. The ic705 is smoother operating than the x5105, even considering the T1 external tuner. And 5 watts with the internal battery worked as well on on the ic705 as five watts with the x5105! I noticed that the internal battery indicator on the ic705 showed I had used between 1/4 and 1/3 of the battery capacity which is a little concerning. I'm guessing 1-1/2 to 2 hours of operating would deplete it whereas the x5105 would probably last twice that long. That and the minor inconvenience of having to use the T1 tuner are the only two "issues" I could see with this setup compared with the x5105. Never thought I'd NOT use the LC192 backpack, as I really like it, but I'm going to stick with this kit for a while and see how it goes. I had the microphone with me but didn't use it.
2021-12-29 The last couple times out I took my x5105 kit which included my 35' version of the GRPGuys 9:1 unun based EF antenna. As I refine my winter deployment using my 10 meter (33 ft) Spiderbeams mast mounted in the DIY drive-on support it is quickly becoming my favorite POTA antenna. That is especially true when using the x5105 with internal tuner. It only takes about five or ten minutes to have the antenna set up and another few to hook up the radio, get out my log sheet, key, etc. and be ready to go. Furthermore, I'm having trouble seeing the five watt output of the x5105 as a problem, at least when operating CW. And I love the small, 4-1/2 lb total package, excluding the mast.
The very positive experiences I'm having with this setup is tempting me to try to use my IC705 similarly packaged! My deployments are typically less than an hour on the air so I'm sure the IC705 internal battery would perform well. My Elecraft T1 tuner wouldn't add much to the package. We'll see!
2021-12-21 This page is titled "My Ideal POTA KIT!" But as we all know there is no such thing. What seems ideal today may seem less so tomorrow. Something inspired me a few days ago to get out my Xiegu X5105 QRP radio. Part of what triggered that was thinking about my random length, or more correctly, my 29' end fed antenna. Since getting the IC-705 I've concentrated on resonant antennas which are very good but do confine one to whatever band or bands they are set up for. Yes some of them cover several bands, like my 40 meter EFHW. Several have taps or other ways to change their band of resonant, like my Wolf River Coils vertical. But they require getting some physical exercise, going to the antenna and changing a tap! But the random wire can be used on almost all bands if you have a tuner. And the X5105 has an excellent tuner built in.
Another nice thing about the x5105 is that it has a very respectable internal battery. So about all you need to operate is the radio, a key and cord (it has an internal mic), feedline and an antenna for a complete kit. In my case that package weighs just 4.25 lbs.
I used that nearly exact setup twice in the last week for two POTA activations and logged 46 CW contacts including Alaska and Porto Rico, 2700 and 2100 miles respectively. It was in the mid 30's and windy so it was nice to stay in my warm car when changing bands! Now I'm back to thinking, depending on ones criteria, this may be "My Ideal POTA KIT!"
2021-10-27 With just over 1500 Parks on the Air activation contacts in ten different parks here in the Midwest I've come up with a pretty stable portable package. I mean, nearly every time I head out it is with this kit. About the only customization may be antennas. But the basic single-bag kit includes everything I need including two dependable antennas. It's not quite "minimalist", weighing about ten lbs, but very portable. It provides for both CW and SSB on nearly every HF band and ten watts output. I haven't proven it but I think it will run between five and ten hours on the included battery. The primary antenna, a vertical, is stand alone. the other, a "random wire" end fed requires something to tie off the far end. I've logged 350 contacts between the two antennas with the furthest distance being just over 5000 miles. I'm pretty much assured of plenty contacts with either one every time I take the kit out. Of course there are always those times when that doesn't happen due to propagation or mistakes on my part. My point is, the kit is easy to transport, easy to set up almost anywhere, and just works!
Top row of photos.
1) The top left photo shows the pack complete and ready to be carried out the door. 2) The top center one shows how it would typically be set up for operating. Connect the key and antenna and all is good to go. I like the simplicity of that. 3) The top right shows the loaded pack open displaying the packed contents.
Bottom row of photos.
1) The bottom left photo shows the contents of the pack spread out. 2) The bottom center photo shows the two antennas. The left side is the random wire antenna and Electraft T1 tuner, since the ic705 does not have an internal tuner. Also shown is my NanoVNA, just in case! 3) The bottom right photo is of my clipboard with logging sheets, mechanical pencil, straight key and paddle with cable to connect the key to the radio. I normally use the paddle but have the straight key as backup. I do my logging manually.
I fabricated a small aluminum bracket on the left side of the pack seen in the top left photo providing external antenna and key jacks. That significantly simplifies connecting the antenna and key. The vertical antenna ground mounting spike is shown on the left side of the pack behind the aluminum bracket. It is a 12" long 3/8" aluminum rod with a 3/8-24 coupling screwed onto top for attaching the vertical's loading coil. The foldable 9' whip of the vertical is collapsed and shown in the pocket on the right side of the pack.
The random wire antenna shown in the left half of the bottom center photo consists of a 29' wire radiator (green) 17' counterpoise (copper) and the QRPGuys mini 9:1 unun. The black bunge cord and yellow cord are for use in suspending the far end of the antenna. All random wire antennas need an antenna tuner, hence the Elecraft T1. The nanoVNA is for testing if either antenna seems whacky!
The small block of wood in the upper right of the bottom center photo is a comfort item. It screws on the top of the ground mounting spike to save your hand when pushing the spike into the ground! Click here for details on that antenna.
I'm under no illusions that this is THE best portable kit. and it may not be my favorite for long! I also have a kit based on the Xiegu x5105 radio. It of course can be paired up with any of the other items, other than the T1 tuner as it has a very good internal tuner. I've logged over 400 contacts with it doing activations compared with just over 800 with the ic705. I also logged almost 500 of my activations using my Wolf River Coils vertical antenna with a 17' whip. It's an excellent antenna, probably better than either of these in my "ideal" kit but is not as convenient to transport or set up. I have about 15 activation contacts using a linked dipole. It is an excellent antenna but again is more difficult to deploy. And I've logged just over 300 contacts with 40 meter EFHW antennas, another excellent antenna but somewhat more difficult to set up and requiring more space. So I recognize this kit is a compromise of weight, transport and setup ease and power. For the moment, and about half of my activations the past couple months it has served me well. So for now....
