The other problem is the IF is near 381MHz and makes the PRO-96 pretty deaf
in this range.

Thanks!  The problem is the Control channel is so weak here I can barely
lock onto because it's 2.5khz off in frequency.  I have no idea why GRE set
the frequency step to 5khz for the 380 to 400 Mhz band. 

I know this range is not officially supported so with the Pro96.  It just
happens to work because I opened it up with the extended frequencies option
in Win96.
