Subject: [Elecraft] KAT500 as a remote-controlled tuner

"Someone asked me recently whether a KAT500 could be remote-controlled"


It wasn't me that asked but I have been considering using the KAT500 as a
remote tuner as I need higher power capability than my current MFJ-993BRT.
However, my approach was going to be to buy just the KAT500 board and
find/build a suitable enclosure.  I'm a bit surprised Elecraft does not
offer the KAT500 board packaged as a weather resistant remote tuner.


As to needing AUX cable and keying interrupt -


      - KAT500 does not need AUX cable to operate but if you want to help it
along it's far better to give it the TX exact frequency rather than just the
band.

     -  What other remote tuners provide keying interrupt?  In any event,
the SWR seen at the remote tuner could be quite different from the SWR seen
at the amplifier and may not be a good indication of whether the amp should
be keyed.


The keying interrupt should be based on SWR seen at the amplifier output.  I
actually already have that wired using my LP100A.
