KX3 Hi-current warning at 5.0 watts on 6 meters

Has anyone seen a KX3 high current warning on 6 meters, but only at 5.0 watts?
4.8 & 5.2 watts are fine - just at 5.0 watts.

My setup: MCU 1.23, DSP 0.99, ATU in bypass, DL1 dummy load directly connected
via a double-male BNC, in CW or USB (haven't tested other modes). The display
shows a 1.4:1 SWR in bypass. With the ATU in auto, I get a 1.1:1 and no issues.

This isn't related to the lower-current PA mode, as that changeover occurs above
3.0 watts in USB. The error message appears independent of which current mode
the PA is in at 5.0 watts, depending on the transmission mode.

No other bands exhibit this.

It's not a problem, just a peculiar quirk.

73,

Mike, KW1ND

A brief followup: this only occurs with the DL1. I tried it just now going
through my LDG antenna switch to a dummy load, and everything works as it should.

As I originally said, it's just a quirk specific to my DL1.

hi mike, I'm new to my kx3 kit and guess what I have the same problem you have described ,hi current on 6m tx but mine is from 4.4w to 5.0w when running off of mains power supply of 13.8v, it's fine on 5.2w and over ( but do find that I then get high temp warning after more than 30seconds tx ? does yours show this symptom aswell ? ) I'm in the middle of trying to resolve it with help from elecraft ( just been a bit busy of late) , did you Actually resolve your issue ? , I too have the atu option fitted

regards

I haven't checked it in a long time. If I get time, I will re-check. I never
did hear from anyone else about it.

In reply to this post by Mike B-12

hi all , thank you for you responses to my query , I appear to have the hi current warning issue sorted by a firmware fix that elecraft have provided, further testing ( when I get my full array of antennas back up ) will hope fully conclude that it's sorted and all is well !

regards

Rory
