[1000mp] re new mark 5 field cw

Tue, 5 Nov 2002 12:53:22 -0500

This is normal and happens with any rig that uses bandwidth control that
is outside of the AGC loop.  A external DSP is a prime example and is
why the use of DSP for achieving a useful CW bandwidth is ill advised.
The proper INRAD filers are the only way to go.  (My opinion, of course)

Have fun with the rig.

Ken, 
Sounds like some signal is getting through your IF
filters and kicking the AGC.  

I had a 1000mp on the bench this week that had about
1400 bux worth of Collins filters in it... nicest
receiver I have ever had the pleasure of listening to,
any mode, any bandwidth.  Don't know if the solution
to your problem lies therein; maybe an additional
filter or two would not hurt.  You neglected to
mention what mode you were operating in and if you
were using any audio filtering.
