Gang, 

 

I have recently built my K3 and have had it on the air about 3 weeks.  I
started small, with 10 watts, added the PA3 and DVR.  My next purchase will
be the ATU module.  In the meantime, I am using an LDG-200Pro Auto-Tuner.
It works great, but I have noticed that especially on 40 meters, I can have
the tuner go through a 'tune' cycle, and it will show 1.0:1 SWR, but my K3
shows 1.3 ro 1.7 up to 1.8 to 1 SWR.

 

I recorded a short call response with the DVR and when I play it back, the
radio shows SWR of more than 1:1 but the tuner indicates full power and low
SWR.  Which do I believe?  Most other bands are normal, with tuner/radio
agreement.   But not always, and especially on 40.

 

I tried to manually tune the tuner to 1:1 and usually only took a couple of
clicks, but no matter what I did, I could not get it to hold those settings;
ie, when I went back to the frequency I 'manually' tuned, and tried to
memorize, it tuned again, often only a Memory Tune, but went back to it's
settings of 1.3:1.

 

Any ideas?
