I'm guessing the other recommendations were for running JT65HF,
because if you intend to do JT65B on 2m-eme, I strongly urge you to
get the TCXO3-1. The standard TCXO is only 5ppm (+/- 140-Hz on
10m). For best operation on 2m-eme one should stay within 20-Hz bw
(+/- 10-Hz). The TCXO3-1 provides 0.5ppm and barely makes that
standard. For best performance the K3EXREF is best as it keeps you
at 0.1ppm: +/- 2-Hz at 28-MHz.
