[Elecraft] VGA Cables

[Richard Squire - HB9ANM]

It is clearly stated in the manual (as mentioned several times on the
Reflector) that commercial VGA cables are NOT suitable for use with the
KPA500 as some wires are grounded and/or connected together.
The KPA500 will work with ANY radio providing PTT to ground. No cable
required, except PTT!

I do have the special cable between the K3 and the KPA500 but I also tried
removing it and connecting the PTT cable only. Since the frequency sensor in
the KPA500 supersedes any other band switching means (RTM!), there is no
need, really, for a special cable when using non-Elecraft rigs. And the
sensor does work, instantly and with only a fraction of a watt drive - even
with the KPA500 in standby!

I've just ordered another KPA500 for a friend (an Icom user), that's why I
tried this out.
So if you have anything else than a K3, don't worry, go PTT. The sensor will
take care of the band switching just in case you forget.

73 and have fun with the KPA500
