[Elecraft] KX3 Option Advice Wanted

Mon May 2 23:55:15 EDT 2022

Like Jocelyn, I have mostly used my KX3 for FT8 digital mode operations, and have 
found it works very well on that mode from 6m down through HF. It is ESSENTIAL that 
you get the built in antenna tuner! It is AMAZING and will load up into just about 
anything!

I ordered mine with the built in battery charger but I don't use the built-in 
batteries at all, so I wouldn't bother with that. When I operate SOTA, I take along a 
3 AH LiFePO4 battery from Bioenno Power, and just plug that into the KX3. I can run 
10w on FT8 for hours with that battery!

I think it's really great that with WSJT-X, you can call "CQ SOTA". It is just too 
bad that the Reverse Beacon Network and the SOTAWATCH website does not automatically 
spot FT8 signals calling "CQ SOTA". However, there is always plenty of activity on 
FT8 and you can spot yourself.

GL and VY 73, Lance
