I finally got around to downloading and trying KS7D
Mike's
K3 Filter Tools program.
I had previously measured the response of one of my filters
by manually sweeping the K3 VFO across the XG-2's
50 microvolt signal and writing down the AFV
outputs
from the K3
display. Then I discovered that I had forgotten
to turn off the AGC, and never bothered to repeat
the
measurements.
Now, with Mike's excellent program, I have some
nice
plots of my K3 filter responses, with and without
the
effects of the DSP filters. I
have the XG-2 connected
to one of the antenna inputs of my KD9SV
receive
antenna box, so I can switch it into the K3
without
changing any cables.
Nice work, Mike!
