[Elecraft] K3 ATU Problem

[Mike Harris]

HI,

After a bit of button pressing I have noticed the following:

When doing a first tune using the internal ATU the tuning power is a set 
5W. Immediately doing an extended tune the tuning power toggles to 10W. 
It does indeed flash up in the VFO B window whilst tuning is in progress.

This is in no way controlled by any power level set by CONFIG>TUN PWR. 
My CONFIG>TUN power setting is 18W which I use to preset my Acom 1000 
amp tuning.

Regards,

Mike VP8NO
