I'm not sure I understand from your description of the problem, whether you
hear the steady carrier in REC after transmit or during transmit.
But, on my Atlas 180, after years of non-use, I had a feedback squeal in
receive when the audio gain was turned up toward maximum audio. If I
turned the audio gain to 3/4 full gain or less, the feedback stopped. Then
after about a week of operating like this, the problem went away. I think I
was lucky and an electrolytic capacitor in the audio curcuit that was
marginal re-formed its dielectric layer and is now functioning properly. If
your 210X has been idle for a long time, maybe it's somethin like this and
not a transmit problem.
