I have a Yeasu 757 & it isnt transmitting on SSB. But AM & FM are working ok. Please can you tell me what is wrong ?

[@brankomihajlovic7662]

Do you have modulation on AM and FM

[@YT7RR]

YT7RR ma problem je mnogo dublji menja modulaciji i u isto vreme bezi od frekvencije pa se vrati i td. Nije trenutno ni bitno prvi problem je bila statika prvi put no u svakom slucaju hvala ma ponudjenoj pomoci sve najbolje pa se cujemo u etru. Branko Knjazevac/Beograd :) 73

With a Dummy Load & external Power Meter, It goes as far as about 85 - 90 watts on FM, 50 watts AM, When using another listening receiver, I can just about hear SSB, But no power whatsoever !

[@dallasdunne6667]

I have the same problem no output only on sideband

[@YU5KBM]

This one turend out to be a bad xtal and a guestionable if transformer after the change everything is bac up and runnin

[@tlrptg]

[@brankomihajlovic7662]

CT or TC I cannot find CT on the schematic but there are TC01, TC04.... variable capacitors. Thanks friend.

[@tlrptg]

yes, TC01, TC04, etc. In some schematics are TC, in other schematics are CT :)

[@leightonlewis4954]

Yes, I do, But not SSB.

[@brankomihajlovic7662]

Ok does it go on transmit but dose not have power or is it not keying at all.

[@dallasdunne6667]
