[Elecraft] K3 - ATU BYPASS relay/circuitry?

[Don Wilhelm]

Stewart,

If you are driving a dummy load and have the tuner in TUNE, you still 
have do do a TUNE into the dummy so the ATU remembers the setting for 
that band segment and into that dummy load.  Remember that with the K3 
ATU, the bands are segmented, so if you QSY beyond a band segment, you 
will have to re-tune.
