Have you ever considered one of the capacitive hats for your #ma12, #jpc12 or similar whip based antenna? I've done some tests with and without using #WSPR: https://www.youtube.com/watch?v=zayHBhak8Kc #hamradio #portableradio

This is one of those: figuring out which stuff is actually still working afternoons. It turns out: my #oscilloscope is working, my #ft817 and my swr meter and my dummy load works, too.
My #ma12 trx which I wanted to test, in the first place is in desperate need of calibration. But, same goes for my KX3 and K2 #tranceivers which I took to cross check first. It took me a while to figure that out, wonder what comes next.
