Cobra 139XLR help with low output SSB

#408163

Post by adamf »

Hi all, I just got a Cobra 139XLR and AM output is fine (5W+) but on SSB (LSB or USB) I can only get peaks of about 6 watts. A adjusted CT7 but that is all I can get. Surely someone good soul out there knows what I can try?

Thanks, Adam in Florida

Hi all, someone gave me some info to replace C154 with a 47pf cap instead of the 22pf cap and now 20 watts out! Adam

Suggesting there was something wrong with c154 , rather than a different value.
