so what should my friend do? what tech should he send it to??
I guess that all depends on where you guys are at.....
It's a common-ish problem with the older Galaxy radios. The same "vintage" as the RCI-2900.
A little clarifier work and realigning the radio ought to be able to bring it back. ESPECIALLY if it's ONLY on LSB... That would point to the offset oscillator being bad.
I DOUBT it's the regulator, since you get power output.... That won't cause freq to shift, either, it will cause the sound on SSB of being overdriven, and on AM you will have a 1-2 watt carrier max and drop BIG TIME when you try to modulate, or you will have a monster carrier, and that's it.
Find a real tech, not someone that reads Galaxie's tech tips and calls themselves a technician. I've found that calling Monika on the phone pretty much finds out that almost EVERY "Certified Galaxy Tech" was, for lack of better terms, completely full of shit.
***EDIT*** Sorry, didn't register the first time you said RCI Certified tech... I still stand by my original statement, though... Anyone that can't fix a problem in a radio that's been KNOWN for 15+ years isn't <<that>> good of a tech... Especially when it's either a clarifier or offset problem.
