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.

At present it is not possible to lock the KX3 to an external reference.
