Hi, i initially built my QDX for 9v using WTST and .6mm wire, i took a couple power measurements into dummy load with a good power meter vs supply voltage. attached here. It was running a bit hot at 40m & 9v.
Then I decided i wanted to be able to run at lower power output for WSPR so i decided to rewire T1 for 12v using RWTST (& 26 AWG). After that I took a complete set of power measurements into dummy load. also attached.
I regret that I didn't take more measurements in the first configuration but i'm pretty happy with the plots for 12v/RWTST. I don't know if my results are typical and/or why 60m is attenuated, but I don't think its an issue for me.
in case this is of interest or helpful to anyone.
regards
