Has anyone tried a +5V to +15V DC/DC to run an OCXO, getting the 5V from
one of those rechargeable USB power bricks. I was thinking about
portable operation.
In my case, the OCXO is something like a Wenzel streamline. I would
think that the DC/DC probably has some noise, but maybe DC/DC to a
higher voltage, then a good linear regulator to clean it up (or would
the radiated noise just leak around).
How quiet is the output from those USB battery things..I've used one to
run a RTL-SDR, but that's hardly a ultimate low noise receiver.
