Thanks for the info Dave ... as you say, not so cheap.?

So far the ECS TCXO on BB01 has been OK ... I can see some 'steps' occasionally,? but the WSPR and JT9 still seems to decode.? The next one will try the Chinese TCXO (cost about $1).

Bob,

I've used a 'Connor Winfield D75F-027.0M' ? TCXO in two U3Ss as it has an analogue feedback loop - avoiding jumps.? Suggested by another poster on the group some months ago.

I haven't done any tests but the original poster was using one in a 10GHz Rx setup after finding issues with the Fox unit.? Not cheap though.
