I'll use Spectrogram and the XG2 with AGC off when I redo it. Good ideas. I only have the FM filter, 2.8khz8p and 250hz8p in the main RX and a 2.8Khz8p and 250hz8p in the sub RX.
I'll also give a look with an N-gen to compare filter shapes. 73 jim ab3cv On Wed, Apr 3, 2013 at 11:43 PM, Brian Alsop <als...@nc.rr.com> wrote: > 8 db. > This number was obtained by observing a signal generator carrier signal in > Spectrogram (AGC off) with the 2.7 KHz filter.
