Hi Alan This is using the digi port on the 857 with all dsp functions off but I need 2400 hz of audio passband just to fit the non standard RFSM8000 signal in and just cant get it from stock standard 857 Maybe just put it back in my mobile and consider other options for digital use - at least the FT920 works well on RFSM Regards Les

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. If you have not centered the signal, or are using USB you will need to turn DSP bandpass off. I don't know how the signalink interfaces, but the 857/897 needs no interface for soundcard/tnc usage and is already decoupled at the digi-port on the back of the radio. Have fun, Alan km4ba
