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 https://picasaweb.google.com/114032640816757126398/XV144FrequencyStabilityModifications
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.

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.
