Re: RFI from uBitx TX after AGC and other mods installed
After I sent this it dawned on me to check the 12v supply as well. Sure enough, it's there too. FWIW, I'm powering it off a 20A Astron 13.8v linear power supply and feeding it into my old Heathkit Cantenna dummy load.toggle quoted messageShow quoted text
I have it installed in one of the amateurradiokits.in cases. The power wiring runs very close to the antenna connection and the final amp transistors. I tried twisting the wires tightly but it didn't make any difference.
If I disconnect the final amp supply line it goes away and there's no noise from the speaker with the AGC board in place.
Anyway, a couple more observations...
