[Elecraft] K3 - Interface to MFJ 998 Auto Tuner

I use my K3 with a MFJ-998 and Ameritron ALS-600.  The K3 doesn't have an 
input YET that puts it in the low power CW tune mode.  I understand this is 
planned.  Once this happens it will be easy to make an interface cable from 
the MFJ-998 to the K3.  Currently I just feed the K3 amp-key output through 
the MFJ-998, and I leave the MFJ-998 in the full auto-tune mode.  When I 
change bands or antennas, I just hit the TUNE button on the K3.  If the SWR 
is greater than 2:1, the MFJ-998 takes the ALS-600 off-line, tunes, and then 
puts the ALS-600 back on-line.

The amp-bypass feature of the MFJ-998 really works well.
