Forward and backward

I had a little bit of time to work on the FT-101s this evening.  I did have a good idea.  I would use the scope to see if the oscillator of the crystal calibrator was working.  On a radio that had a working calibrator, I was able to get a decent wave on the scope.  On the radio that it wasn't working on, I got nothing.  That tells me that there is something definitely wrong with the board.  I build my own extender card to test the Regulator board.  I did some voltage and resistance checks, and they were a little out of wack, so more investigation will be needed.
