Bill, You did notice that i stated i can't speak for the FE-5680A? All that I have reference too are pictures at the moment.
My help files? I don't run windows, thanks. But the reason I asked here. Also, I was under the impression that Rb ovens operated around 80c if the Rb oven gets that hot that it had oxidized... Comments on the crystal? Is the crystal heated or a LF acoustic resonator?
