Sideband problem solved
 

Astron RS-35M took care of that. At least I now have a supply for my ham rig
when I get it. Thanks for eveyone's help here.

Well, I of the 2 problems is solved. The cutting out on SSB after 3 seconds is
solved. The Astron took care of that.

But I am still having that "carrier" problem on SSB. For some reason, as soon as
I speak into the mic, the radio holds power, as if it were on AM. The TX meter
on the radio shows this, and the SWR/power meter shows this. The power is not
fluctuating with modulation. The power is not high, about 20 watts peak. Seem
the previous owner had it turned down. Like I said, it seems to do this as soon
as I speak into the mic. Even a subtle noise will send it to max, and stay
there. Changed mics, and have the same problem.

I am going t try this in the car and see what I get.

This is a common problem. In many cases, if you remove the cover the
problem will go away. The final stage is going into oscillation and
the "carrier" you see is that oscillation. Usually (and unfortunately)
the oscillation falls in the 29 Mhz area.

Sometimes this problem is caused by added mods that people add to try
to squeeze a few more watts out of it. There are added capacitors on
the bottom side of the board that can cause this. If you see an extra
cap (or two in parallel) on the underside of the board connected to
the final, remove it and that should cure your problem.

Thanks. I have not added any mods. I wanted to add some Schottkey diodes for the
receive. However, I have not gone thru the radio to see if the previous owner
added any mods.

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

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.

people are totally flying blind with radio butcher mods like that.

I don't recommend any aftermarket performance mods. Too often they do
more harm than good. The exception to that is the final transistor mod
where they replace the original transistor with a stud mount MRF 455.
I accept that mod, not for performance enhancement, but because the
MRF 477 is no longer being made and if one needs to be replaced, this
mod may be the best alternative.

I haven't found any mods on this yet. I was going to to that Schottky diode mod
for the receive. Not sure if it will improve that much for a base use unit, as
opposed to mobile.
