Hello Olli,
The advantage is that I could possibly pull out the RTS line from my one RS232 cable
to the computer, and simply add it to the amplifier PTT plug in ACC2. I would not
have to build a transistor switch to directly trigger the PTT line, which would have
to be broken out from the custom MIC plug.
There appear to be several different ways that I could force the KX3 into XMIT from
the computer's RTS serial port line, and I will have to try to figure out the
simplest way, with the KX3-compatible plugs that I can find. I THINK I could plug a
standard right/left audio splitter into the MIC jack, and plug a mono mic plug from
my headset or the computer LINE OUT into one side and a PTT signal (from a switching
transistor activated by the RTS line, or from a footswitch) into the other side.
I think I may have to wait until the KX3 arrives, and I can actually see how the
connectors (and computer cables) work with it, before I can make a final decision on
what course to take. Like the K3, one of the big advantages seems to be that it is
very flexible radio, and there is probably some way to make it do just about
everything you need ;-)
