saw no change in the spectrum.

         Congratulations Mark...I think you've discovered a bug which the
team missed in 1.371.  We've been actively discussing 500/250 Hz filter
for fixing in 1.372 and I'm sure Gary is working on it as we speak.  Please
QRX and it should be fixed soon.

I would be interested in knowing what the problem is that is being
"researched?" I ran a bandwidth test, using the spectrum facility in
Hamscope and I can clearly see the bandwidth (Displayed as an amplitude
peak) of the 250Hz filter. I can also see the 500Hz, the 1KHz, the 1,8KHz
and the 2.4Khz. The 6KHz and the 20KHz are wider then the spectrum display
in Hamscope. So I'm not sure what Mark discovered? And Bill, I'm not sure
what the 250Hz filter problem is that is being worked on. Do you know more
about the problem? My test indicates the 250Hz filter is working as
