[Elecraft] KpA500 to K3 band change,fault/status

[Leigh L. Klotz Jr WA5ZNU]

The K3 has a per-band/per-antenna DIGOUT1 line on the 15pin AUX connector. 
If you use the Elecraft 15-pin AUX cable, DIGOUT1 is tied to the KPA500
inhibit line.  So, DIGOUT1=ON means AMP INHIBIT=ON. 

For example, if you have a SteppIR (which can be resonant at 40m and up) on
ANT1, you can set DIGOUT1=ON on ANT1 for all bands 30M and below, and it
will never key the amp on the low bands for that antenna.  If your have ANT2
connected to a 40M dipole, for example, you could set DIGOUT1=ON for ANT2 on
all bands except for 40M.

Even if you have a high-power external ATU, you might still want to set
DIGOUT1=ON for 60m and 30m, (though the US does allow up to 200W on 30m).
