[TenTec] AGC thump

[Paul DeWitte K9OT]

Having read several references to AGC thump, I am not sure what it sounds
like. My Corsair II on transmit will have a thump on keying. If I turn down
the AF gain or the RF gain the noise will dissappear. Is this what is
refered to as AGC thump? My Omni D has none of this. Smoothest cw rig that I
have run yet.
If this is what is referred to as AGC thump, do any of the mods that are
around get rid of the thump and still retain 100% of the breakin?
Maybe I have an entirely different problem? I can live with it but would be
nice to get rid of the thump.
Thanks 73 Paul K9OT
