Depends on what vehicle I’m in, and what park I’m activating, and if I’m going SOTA as well.
Bronco for a day activation I’m running an Icom IC-7100 with a 53’ random wire End-Fed antenna. If I’m activating multiple parks in one day in the bronco I just use my ATU loaded 108” whip.
If I’m going to be base camp I run a Yasue FTDX10 with a DX Commander Classic multi-band 1/2 wave vertical 80-2m.
If I’m in my wife’s 4Runner it’s the FTDX10 with a 160m OCF Dipole at 100’ in the air.
If I’m going to be doing both POTA and SOTA I use a QRP Labs QCX Mini on 40m and an Anytone 878 plus 2
The 7300 is a great radio, but as a mobile for POTA it’s kind of a bear… it’s best to be used at a base camp or as a home base station… Unless you have lots of room for your batteries, charging system, and the radio itself. My FTDX10 is about the same size as the 7300, and that’s why it very seldom goes out for day POTA use….
