[time-nuts] Naive reference oscillator qustion, but has to be asked!

[Erno Peres]

Hi Chris,

the Kenwood  TCXO module is quite adequate because the microwave transverter LO is the major problem... let say a 10GHz/144 transverter LO xtal  osci is 106,500MHz and multiplying up  to 10GHz   / fxtalX96 / is more critical  to get exact 10368,000MHz....

Rgds Ernie.

Thanks, is it worth even thinking about, or is the Kenwood add on
CXO module more than adequate? Only reason I ask is I will be using the
ig as a driver for a microwave transverter.
