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.
