[Elecraft] KX3 WSPR and heatsinks

[Dave Lankshear]

Don't overlook doing the extended temperature calibration procedure

I've done it on a small number of KX3's and the improvement in thermal
stability is considerable.  If you haven't run it before, it's time
consuming so be patient and be prepared to re-run it as it's easy to make a
small mistake.  I also had issues with getting it to work on one of the
KX3's (mine, naturally) after running straight through on the others.  It
couldn't all have been finger trouble, but after multiple, patient re-runs,
it went through and my KX3 is now remarkably stable over a wide temperature
range.  It was well worth the effort.

 

Season's Greetings, one and all.  73 Dave G3TJP
