Hi Andy,

The OCXO should be fine to drive either DEMI or DB6NT transverters.

On the VFC pin, they usually tune over a range 0-5v. Sometimes you can just let them float, but it's usually better to tie them to a stable voltage source. You really need to measure it to find out. I personally would not let the VFC pin float.

Hi,

I bought 10mhz OCXO Trimble from ebay and I can't find any datasheet so I'm looking how to connect the pins VFC Vref and if this OCXO is good enough for 10Mhz reference for transverters maybe (like db6nt, demi). Can I leave pins VFC and Vref not connected? Any helps very welcome,

thanks, regards AB
