[R-390] DSP IF

[Tom Norris]

I have tried the IF out to my Pro II. Works well. Just put the
390/390A in 16KHz, erm, I mean 16 KC bandwidth and connect
the IF out to the Pro/ProII/ProIII *receive input* (so you won't
transmit into your 390!!) Works great! I have considered taking
the output directly from the final mixer before it goes to the
IF deck, but have been too lazy to try since it involves taking the
top cover off, which I can't do since the radio is in a rack (an open
air rack, in case someone fusses) and I am especially too lazy
to pull the radio, and my back, just to get a few more KC of band
width.
