I still need Rf probe spectrum Analyzer and more knowledge. I got the passion, the patience, and more time now, thanks COVID19 lol.
the radio on the bench is ready, it was the one with High DK watt problem
this is us wwdxforum ,(y)
so what i choose for AM/SSB radios dk or pep, let see for DX I go for pep for AM local dk mmm, rf circuit is complicated. on this case i think i deal with 7.8 mhz signal loose some where for ssb or audio pat like some wrong capacitor value. i do not know any thing...
Something not right if a pick and tune the radio on SSB I get about 18 watts, on AM drop to 1.5 watts. Now if I pick and tune on Am I get 4 watts swing 18 watts,and SSB drop to 12 watts what’s wrong whit this issue.
