Les,
According to the RFSM web page, you need at *least* 300 to 3000 Hz audio
response, and preferably 300 to 3400 Hz. Even an INRAD filter is not going to
completely meet the 3000 Hz high end requirement, much less a 3400 Hz
requirement. I think some other Yaesu rigs optionally support a 3300
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
Hi Skip
The problem is that I need to pass around 2.4 khz of signal audio
and with the stock filter it will not do it - have to look at a wider filter or
an IC7000 hihi

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.
If you have no
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
Greetings to all
Is anyone using the FT857 for RFSM8000
I have been trying mine out over the past two days after getting a
new Signalink USB interface
Big problem with the RX passband - it is not wide enough using
the standard filter supplied with the FT857 and consequently too
much of the signa
Kinda spam, but I thought I would pass this along.
