Thanks Mike...I will try that POT...and your idea re: cut off on the
filter is along the same lines as to what I was thinking...especially
since the ssb power output (heard) is lower as well...a friend is
bringing over his IFR so I will have a go at that too.
Cheers

In every rig I've owned there was an internal pot which balanced the
offset
pot on the panel between transmit and receive. The Argosy II manual
shows
the Control Board 80781 on page 3-25. My best guesstimate in that R1 on
that board is that pot. I'd give it a go. I might even phone Ten-Tec
to
get their advice as I can find nothing in the manual about adjusting the
pot.
About the power's being lower with the 8-pole filter, two things come to
mind: first, is it a Ten-Tec filter; and second, if your carrier
oscillator
is not properly adjusted, the narrower skirts of the 8-pole filter may
be
attenuating your signal.
