Hi Paul -
Oh, heck, if it doesn't bother you why worry? (Remember MAD magazine
and Alfred E. Neuman with his "What, Me Worry?" My dad always thought
I was a little like Alfred!) I tried out a "mod" to the AGC on an
Argosy II and it killed the QSK sharpness. I didn't like it, the AGC
went "soft" on me.
The "thump" is when you are listening to a quiet band, then suddenly a
big signal (over S9) comes up and the receiver gives a "pop" at that
instant. Not a big deal, doesn't bother me much either. When you take
down the RF gain it will disappear (takes the signal to the bottom of
the AGC range) so that will "solve" it anyway.
I notice a bit of a thump on transmit also, but it is not a big deal to
my ears, just a minor result of that wonderful QSK of a Ten Tec. I
believe the engineering tradeoffs of very fine QSK (biggest priority:
allowing me to hear the band in between my transmissions) don't quite
involve perfection, but give me just what I need ... and better than
other kinds of transceivers.

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
