Hi, John,
As far as I can tell from the schematic, the PTT_IN jack and the ACC jack
pin 4 are a wire-to-wire connection at Q3 on the KIO3 board. Power on, see
if both PTT_IN center and ACC jack pin 4 show the voltage to ground for
PTT. See if the voltage on one drops if the other is grounded.
You can frequently find RG400 jumpers for sale on eBay, with useful
lengths, even if you have to cut off the connectors already on them.
They sometimes have one or more BNC connectors already on the cable.
RG400 is still made new and is rated for the kinds of sharp bends that
are found in aircraft
Vic et al,
The currents on a particular wire of a two wire feedline, will always
be the vector sum of differential current and common mode current.
This is not the same thing as forward and reflected, which are both
expressed in the differential current. The tuner will be able to
control the
Interesting, but wouldn't you also have to know which ANT jack on the
back of the K3 had the KPA500? How is it possible for the firmware to
know? The rule would be if KPA500 enters Operate mode and the K3 is
switched to the ANT jack that had the KPA500

Hi Don,
Every now and then on this subject, I have to throw in this rather
significant (IMHO) caveat on all this talk about how good the DSP
bandwidth is. I have an old MP, INRAD 8 pole filters in 8 and 455
IF's, that has selectivity just barely matched by a K3 with 8 pole
roofing filter AND DSP
Yeah, but Vic never had a chirp, or click, or mushy CW, just a
southern drawl fist on a bug that you would never forget, and would
recognize instantly as you tuned by his run frequency in the
sweepstakes. http://pvrc.org/wav/W4KFC1971.mp3

Last time I had a problem like that, it was the monitor, and it needed
to calibrate or something like that. It was one of the monitor menu
items. Ran whatever that was on the monitor and all was cool. 73,
Guy.
