I'm trying to complete the alignment and setup on my newly completed
XV432. I'm going to use it with my KX3.
I made a cable so the KX3 can key the XV432 to transmit. RCA phono plug
at the XV432 and a 2.5mm stereo plug for ACC2 on the KX3. Center pin on
the phono plug connects to the RING on the stereo plug. Whenever I
connect the two units together with the cable the XV432 go into
transmit. If I unplug it from the KX3 it goes back into receive.
I checked that only the RING and ground are connected at the stereo
plug. I have checked for shorts (ring/center pin to ground) and
continuity (from ground to ground and RING to center pin) many times and
everything is OK.
With the cable plugged in to the KX3 I measure infinite resistance (open
circuit) across the phono plug.
The RING terminal is not affected by ACC2 IO menu settings.
My understanding is that the keyline goes low during transmit, according
to the KX3 manual. It's not low when I check it on receive, but it
still keys the transverter when I connect the two of them together. I
think I've covered all possibilities, but they aren't working together
the way they should.
Anybody have any ideas. I'd appreciate any help.
Thanks and 73,
Ken Alexander
