[Elecraft] Elecraft Digest, Vol 124, Issue 15 KX3 CW Drift

Focus Group Thoughts for Elecraft  Re: KX3 and K3 drift on VHF Digital Applications


What about adding an external phase lock option that would also allow
the 10 MHz reference phase lock and GPS sync?  Many of the digital mode aps are
needing this kind of stability and the KX3 with an internal 2 meter board or external XV transverter family choice.  The XV series transverter LOs could have a kit for phase lock too.  


There are so many interested in WSPR and you have one of the gurus up north of Elecraft who's already done a design.  This also would bring the Elecraft product up to what's new and state-of-the-art for both the K3 and KX3 in digital communications....

This is within spec, though we're still looking at ways to further reduce it.

HZ or so.  Is this the natural drift of the 2M unit I'm seeing here?  If so I'm 
assuming that's as good as it gets.
