[Elecraft] KX3 Reference Oscillator - Ext locking?

[Edward R. Cole]

I have the new VHF ApolLO synthesizer board from N5AC (marketed by 
DEMI) and wondering if I could somehow use it to drive the KX3?  What 
is the main reference oscillator frequency?  What level of signal is produced?

The ApolLO can be programmed over a range of 78 to 409 MHz so if the 
KX3 runs at 49 MHz like the K3 one could run 98 MHz and add a 
divider.  This might require special programming of the synth by N5AC 
but just wondering.

This would be an external module (size: 3x4x1/2 inch).  One could 
take this one more step and add a GPS receiver for portable 
operation.  The GPS would provide the accurate reference 
signal.  These are now available with tiny patch antennas integrated.
