[Elecraft] Interface question.

[iain macdonnell - N6ML]

I have an MFJ-998. I wish I'd known better when I bought it - I
wouldn't buy another (for various reasons). I never found a good way
to integrate it with the K3... so the tune-up procedure involves using
the K3's "TUNE" function to produce a low-power signal (CONFIG:TUNE
PWR) and then invoking the "TUNE" function on the MFJ (it's configured
in "Semi-Automatic" mode). When the MFJ finds a match (or doesn't), I
tap "XMIT" on the K3 to end the "TUNE". There is a fully-automatic
mode, where the MFJ will initiate tuning when it detects SWR above a
configured threshold, but I had bad experiences with that in the past.

If the K3 had a way to feed a signal into the ACC connector to trigger
the TUNE function, the MFJ could utilise that. The suggestion has been
made a few times, but it's probably not a high enough priority on
"Wayne's list".

Aside from the KAT-500, it appears (from their website) that PalStar
are working on a new remote-able autotuner rated for 2500W. I'm sure
it'll cost a lot more than the MFJ, but... you know what they say ;)
