[Elecraft] Externmal ATU

[Don Wilhelm]

  Phil,

I am not certain if you or someone else originally asked the question - 
but --
The K3 can provide a lower power RF source for tuning.
As others have mentioned - first set the Tune power in the menu.
Then use TUNE (not ATU TUNE)  and the K3 will transmit at the power you 
set in the menu.

How you command the tuner to initiate its tune is quite a different 
matter.  Perhaps RF sensing is appropriate - or one would put the K3 
into TUNE and then operate the TUNE button for the tuner.

73,
