[Elecraft] Surprising Behavior on KX3 KXPA100 Combo

[Phil Hystad]

I have configured my KX3 with my KXPA100 (previously used only with KX2) following all instructions (I think) in the KXPA100 user manual.

First comment — everything works, antenna tuner on KXPA100 works, power out 100 watts on all bands, and so on.

Weird stuff:

1.  I Held Keyer/Mic/PWR button for power display, showing 100 watts.  Then, I immediately pushed Band+ to switch up to next band.  No band switching too place but the display changed from 100 watts on KX3 back to the clock.  Pressing Band+ once more results in band switching as expected.  This happens every time in the sequence I describe and I am wondering if (a) this is normal, (b) something is not yet configured correctly.


2.  My reason for Hold on Keyer/Mic/PWR to display power is because after switching bands and after tuning the antenna for a low SWR (about 1.1:1) the power output was only about 10 watts.  I did a Hold on Keyer/Mic/PWR to see the power output and it was indeed 100 watts and not 10.  I then keyed down and then the output was 100 watts.  This does not seem normal to me.

None of these two behaviors occurred on my KX2.

Any ideas or comments?
