Good catch, Gary. AGC settings are the missing piece and probably why some people aren't seeing this. With an S9 signal, NR=F4-4, BW=2.00, I get the following results for different settings of AGC THR and AGC SLP when NR is engaged:
THR=2, SLP= 0 +10.0 dB THR=2, SLP= 5 + 2.7 dB THR=2, SLP=10 - 6.0 dB THR=2, SLP=15 -15.5 dB THR=4, SLP= 0 +15.2 dB THR=4, SLP= 5 + 9.6 dB THR=4, SLP=10 + 3.6 dB THR=4, SLP=15 - 3.8 dB THR=6, SLP= 0 +16.6 dB THR=6, SLP= 5 +13.3 dB THR=6, SLP=10 + 7.9 dB THR=6, SLP=15 + 1.5 dB THR=8, SLP= 0 +18.3 dB THR=8, SLP= 5 +15.6 dB THR=8, SLP=10 +11.7 dB THR=8, SLP=15 + 7.0 db 73 -- Joe KB8AP On Apr 25, 2009, at 8:21 AM, W7TEA wrote: > > Joe, following your instructions, I cannot duplicate this on my rig > listening to a S-9 signal.
