[Elecraft] Interface question.

[WILLIS COOKE]

I have had similar experience with a MFJ-927.  I spent a lot of email time and 
phone time with MFJ and finally came to the conclusion that they had hired a 
programmer that was not a ham and had a poor grasp of the normal requirements 
for hams and transceivers and thought that an SWR of 2.5 or 3.0 to 1 was 
perfectly all right.  This does not meet their spec, but all they were willing 
to do for me was send me another unit with the same algorithm.  After the third 
one, I tired of the experience and bought a TS-480 which I should have done in 
the first place.  Why not another K3?  No mobile mount and no split architecture 
and the TS-440 that I was using was just too big for the mobile.  The MFJ-927 
seemed to be OK if I manually initiated the tuning, but that was pretty awkward.

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 ;)
