Hello I have a 142 that has no tax power output but keys up a radio beside it dummy loan to antenna and can see little rf on the scope threw the rf chain cans. On the receive end I got a snow sound and pick up a local here but he’s close and very loud on other radios but here’s the odd thing all functions of this radio works lights controls switches and all except squelch it changes nothing. The radio has not had any mods done to it still the same glass bulb meter lights even. What I did first was recap radio like I always do to these old cobras and nothing changed so pulled driver and final checked on transistor checker and they are good so now what lol ssb also does not work tx or rx plugged external speaker in pa and have audio in both modes. I can lock and unlock VFO voltage can so that works any suggestions will help me get this back up and running for a local that’s down hoping to get back on air thanks again for your help I’ve loaned him a 148 til I get this working again I’m just really learning to help out this hobby in my area there is no one here that works on radios anymore so a little help will is greatly appreciated thanks
