Well, I was beginning to wonder when I could do this again…comfortably. 😂 I have been operating from the truck for so long now, that I felt like I was at a new park when I went to my old favorite picnic table.
So for this “special” event, I wanted to take something out of the ordinary for me. So I used the Penntek TR-35 radio (this doesn’t fit that description but the rest does) and fed it through my vintage Ten Tec antenna tuner to a 65’ random wire with a couple of 10’ counterpoise wires.
To make tuning simple and fast, I use my nanoVNA and simply unplug the BNC from the radio and plug it into the VNA, adjust the tuner for a nice reading on the VNA for the band I want to use and then transfer the coax back to the radio. This way I am not transmitting carriers over the air while I tune and I can visually see what is happening while I tune. It just makes it so easy for me.
Something that I also built for this is the powerpack/speaker unit. This device houses a Bioenno 3aH battery and I installed a couple of speakers as well as a volt meter (that is activated via a push button to prevent battery drain by the meter) and a Anderson powerpole port (added after this activation). I wanted a device that could essentially “complete” the TR-35 sans antenna… It is missing a key of some sort that might just get added a little later. A simple straight key built into it somewhere would be pretty sweet to be honest.
The next thing is how I put up my wire antenna. I first threw a line over this huge tree limb and pulled the wire over it.
Then I threw the line as high into this tree way back here as possible and hauled the wire up about 30’ or so into that tree. It is making a horizontally run wire of sorts and work’s shockingly well. It also keeps the wire out of the way of park goers as well.
All in all, this map shows how well the little TR-35 with a 65’ wire up in the trees worked. I even dialed up some DX on 17m before finishing and worked FY5KE in south America before going QRT and breaking it all back down.
So I look forward to working many more ops at my local park with my little QRP radios in the coming weeks and not being bound to my truck so I dont freeze to death in the process like back in the winter.
