You nailed it on the head. Cover off, oscillation gone. Now I have to

Rebias the output.



Damn !!!!

I was hoping I didn't have to use a DMM. The DMM I have doesn't have
current
measurements. Well, it's not mine. Mine was actually (Fluke 77). stolen. I
have
a scope, and freq counter. But to way to adjust bias current. I will ne to
get a
hold of another DMM.

I have seen the same situation you are describing in a 2510. The guy never
used it SSB, and it worked fine on AM. He later sold it to someone who did
use SSB. Turned out the "Tech" who did the frequency mod on the radio was
also asked to tune it for maximum. He did so, but never noticed it went into
oscillation on SSB. After resetting the bias to the correct level, the
problem went away.

Hope this helps.



Does help. Thanks !!!!!!
