From the manual: Frequency Stability: +/- 1 ppm typical over 0-50 C. An extended temperature compenstation procedure can be applied for improved stability (refer to our KX3 web page).
So for operation above 20 MHz, you need to do the extended temp compensation. I assume they don’t require a TCXO, but rather equivalent stability and accuracy. http://www.elecraft.com/manual/KX3%20Custom%20VFO%20TC%20rev%20A9.pdf <http://www.elecraft.com/manual/KX3%20Custom%20VFO%20TC%20rev%20A9.pdf> wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Feb 3, 2017, at 10:11 AM, Aaron K5ATG <k5atg.aa...@gmail.com> wrote: > > I'm looking into possibly getting involved in MARS.
