    Cobra 142gtl no audio on AM transmit but yes on SSB transmit

    Yeah I should have check electrolytics beforehand. I'll post my results. Thanks, guys!

    Cobra 142gtl no audio on AM transmit but yes on SSB transmit

    I have a Cobra 142gtl with no audio on AM transmit but it does have audio on SSB transmit. My guess is I overdrove the Darlington pair direct injecting it years ago maybe? Would that take away my audio on SSB, too, though? just trying to think what I fried. Any help would be appreciated.

    5/8 Wave groundplane 1.5:1 SWR all over the band

    i just feel like a soldered connection is better than two points only touching. Not sure about this "JoGunn". im just a hobbyist. i dont claim to know it all or know better than others.

    16 transistor project

    i did get the amp going. had help from a friend who has built them in the past.

    5/8 Wave groundplane 1.5:1 SWR all over the band

    It's not that I don't understand SWR or reflect or impedance, I'm just a perfectionist I guess. I like to see an antenna as close to perfect as i can (and coax). Maybe it just eases my mind to see a 1:1 match. Thanks for all your guys input. direct fed at the match: coax is directly soldered...

    5/8 Wave groundplane 1.5:1 SWR all over the band

    Absolutely! 1.5:1 is unacceptable to me. Too much reflect that can damage my equipment. Well i feel stupid. It was a bad jumper. Sorry guys and thanks for all of your help! 73, 677

    it hasnt rained in a few days

    5/8 Wave groundplane 1.5:1 SWR all over the band

    It's a Hy-Gain Super Penetrator 500 but the coax is fed at the match directly. Same location that the SO-239 was connected. Below Ch.1 the SWR starts climbing to about a 1.9:1. Same with above Ch.40. stays around 1.5:1 on the regular 40. All my grounds are good. No power lines or anything around...

    16 transistor project

    ah!!! i see. i will do that. Thanks. What able input tune? how do i change that? the plans did not include any variable cap. also, do my combiner and splitter look like they are wound right? ive never made them before.

    so youre saying to separate the foil of the transformer from the clad board better?

    16 transistor project

    Thanks for the quick reply! i looked over my schematics and didnt see anything different. that doesnt say much though since ive never built an amp before. could you explain a little more please? im attaching the schematics.

    16 transistor project

    Let me say first of all, I’m no tech. I don’t claim to be. I’m a hobbiest with an interest in modifying and building. This is the first amp protect I’ve ever taken on. I built this 16 pill amp from the plans found on this forum. They are the exact plans that I’ve found on other forums. The only...
