Hi Alan
This is using the digi port on the 857 with all dsp functions off

RFSM8000 signal in and just cant get it from stock standard 857
Maybe just put it back in my mobile

Les,
Are you sure it is the IF passband? If your BFO injection frequency is set
correctly, you should be able to pass 300 to maybe 2200 Hz. Otherwise, SSB
phone will have no lows.
If you have audio transformers in a homebrew interface, make sure they have the
necessary frequency response. The
Hello,
You should be using the digi port, and there is a specific setting that
allows you to center the filter passband around typical digi signals. I
find 200 hz up works best for ALE.
Since the signal is now centered, I can then even use the DSP bandpass
to really tighten up.
