[Elecraft] [KX3] SWR Reading Instability Follow-up

[Gary Hawkins]

Firstly thanks to everyone for your input on potential causes of SWR 
reading instability with my KX3.  Since there were so many possibilities 
(antenna, heating, radio, etc.) I knew I needed to go back to basics and 
initially test the radio with a dummy load on the bench.  Well, I 
managed to recreate the issue and have documented my findings in a short 
4 min video, http://youtu.be/cwxk4E01IfM

In short the problem appears to be associated with the KX3 reporting of 
SWR in SSB mode.  My radio is configured as follows: uC 01.79, dSP 
01.27.  As this issue has only recently developed (last month or so), 
and while I can't be 100% sure, I think it may have occurred after I 
upgraded to this firmware version.

I'll be contacting the folks at Elecraft to get their opinion on this.
