[Elecraft] KX3 Reference Oscillator - Ext locking?

[richard allen]

Hi Ed,

I could never understand why folks think it’s so important for the I.F. radio (flex1500, kx3, whatever) to have a serious need to be locked to a 10 MHz standard.  

It’s the down converter that really matters and using one of n5ac’s nice little apollo boxes handles that nicely.  The I.F. radio is normally within a few hundred Hz and that error does not multiply.  It is translated directly to the output  
frequency by addition of the L.O. so it doesn’t matter much.

Regards,
