[Elecraft] XV Transverter Local Oscillator -- GPSDO?

[Carol F. Milazzo, KP4MD/W6]

I have achieved frequency stability to 1 Hz with the Flex-1500 & Elecraft
XV144 transverter combination, using a GPS disciplined OCXO on 116 MHz. I
have documented the XV144 frequency stability and drift data comparing the
GPS control against the stock crystal oven option with enhanced thermal
insulation here

The stock FLEX-1500 TCXO is sufficient to hold the frequency to within 1
Hz. Enabling the 10 MHz sine wave external reference on the FLEX-1500
should increase the frequency accuracy and stability to the millihertz
range.

Hi Guys and Gals,

Does anyone know of a mod to the Elecraft XV transverters that provides for
10 Mhz GPS disciplined oscillator control of the transverter local
oscillator?

I think that would be a popular feature for Elecraft to consider on future
versions of XV transverters.  It would be similar to the K3EXREF Frequency
Lock Option for the K3, which works flawlessly.
