[R-1051] URC-104 TXCO needed

[paul swed]

There are a lot of choices today to replace that TCXO and you could go a
bit crazy with PLLs and such. But is it a soldered can? If so those can
often be opened and perhaps you can find out what died. I have opened cans
like that and been able to fix things.
Just a thought.
