Hi all!
I've been using my 990 for a couple of years and love it. I recently bought
a NIR-12 audio DSP unit that seems to work pretty well. The problem, of
course, is that _all_ audio from the radio goes through it, so when I'm
operating CW, depending on the NIR settings, I can't hear my own sidetone
because it is processed 'out'.
The NIR 12 has a 'bypass' jack on the rear that will turn off processing
if grounded, the idea being that keying a transmitter will let audio like
keying tones through. It looks like the only way to get a signal like
this from the 990 is via the data or packet port, but even if I figured out
the wiring, it still wouldn't pass the keypress tones.
I'd like to hear these tones. Does anyone know of:
1. an easy way to get the xmitter switching signal?
2. a mod that sends the tones directly to the radio's speaker even if an
external speaker is connected?
Thanks!
-Brian
