[Elecraft] [K2] Tuning a magloop with KAT100

[Don Wilhelm]

Brian,

There is no need to tune into a dummy load first.  When the ATU menu is 
set to CAL, the L and C elements in the KAT100 are bypassed.
There may be some residual L and C in the PC traces and relay contacts, 
but that should be minimal.
Yes, you can use the TUNE button and observe the SWR on the K2 as you 
tune the loop.

Be aware that the TUNE with the KPA100 in-line and powered will be at 20 
watts unless you set the power knob to a lower level.
