Ok, first the setup. I get the opportunity to do some ham radio on the big island of Hawaii. It is with about a two week notice and we are flying. Of course, I have this primal fear of my check baggage not making it to the destination with me or ever for that matter. So I have to carry my radio in my carry-on bag… with me. This bag has to house the radio, power source, antenna and any accessories I need as well, such as CW key, headphones, etc. The other bag will have my camera gear so it is pretty much full already. I will balance the load to get everything in those two bag though.
This is the little radio I finally decided on, the Elecraft K1.
So now you understand what I can take is a small QRP radio with a simple wire antenna and some sort of battery. It will be a cw rig, which typically perform better at QRP power levels anyway. At least this is what I have seen when attempting to work POTA with SSB at 10 watts… The radio I initially chose was the Penntek TR-35. It is really small and has all the bells and whistles I like to have on a POTA outing (which is what I plan to do while there) and I just plain like this little radio. I started immediately working on a resonant antenna for it so I could fore go the tuner and quickly realized that wire antennas are not really reliable for resonance without a lot of extra effort on site. Moving the wire around will change SWR. At least it did while I was experimenting with radiators the other day. I spent several hours with my nanoVNA and an EFHW and found I could easily get the SWR maladjusted by simply moving the counterpoise so I have some more homework to do on that before I am up to speed on that kind of antenna.
This is the situation so far, so now what do I do. Well, the solution is to use a different antenna and that means either bringing a tuner or some other kind of antenna that is more bulky. Well, due to space constraints, I chose to use a different radio.
Backing up and punting, so to speak, I chose the Elecraft K1 and a random wire antenna. The K1 that I have, has an internal antenna tuner that the TR-35 lacks so I don’t have to contend with getting the antenna just right once on location. This is a huge bonus since now I dont have to deal with possibly having something happen to the antenna and not being able to get an activation. I can tune just about anything with the K1.
So what does the kit look like now? I have the following:
Elecraft K1 (4 band radio with ATU)
Gemini travel key
41’ random wire with various radials
(8)AA battery pack for remote power. Emergency backup.
Small earbud headphones
Messenger bag style carry bag to house the goodies. (Peak Design Everyday Messenger)
Notebook and pens for logging
Throw line and weight to get antenna in the trees
Misc. little widgets like the BNC to screw lug adapter and a power cord for the cigarette lighter socket in the car.
8Ah LiFePo4 battery with charger.
There is probably a few more little items I have not mentioned here but you get the idea. This will allow me to setup a QRP CW station and work some epic DX stations that I normally dont hear at my home QTH. At least that is what I am hoping for…maybe I will actually be able to work some of those Japan calls I keep seeing in the evenings! Now I have worked QRP for a long time and I am fully aware that I may not even hear the next island, it is the nature of the beast. But I can usually squeak out at least the ten needed for an activation. So I am hopeful that it will work out. The only caveat is that I will have 2000 miles worth of ocean in basically every direction so the take off angle of my antenna is really important. I am hoping there will be a tall tree so I can get it as vertically oriented as possible. This will give me my best shot at getting an activation.
Oh, to be honest, I am pretty sure that this is not the simplest radio I have ever had, but for a portable system that will cover multiple frequencies effectively, the Elecraft K1 works really well. I really think this rig is a great combination of features and it is sad that Elecraft no longer makes this radio. If you love QRP then I can recommend this little radio…as long as you can live with just 4 bands and CW…which I can.
So there you have it, the radio going to Hawaii… wish me luck!
