All good info Mike Including the receiver stuff.  Thanks.
The gent that I got it from said that he had personally removed it from 
the B-29 but he could have been mistaken.  He said that it was working 
when removed and hasn't been powered on since.  Plugs U-7 & U-8 have 
their mating connectors plugged in.  Each has a few inches of original 
cut wires attached to the connector.  So this would lead me to believe 
that it hasn't been "ham-hacked". Of course actually looking inside 
would be the sure way to know.

Is checking the crystals in the crystal oscillator as simple as removing 
the transmitter top cover and then the top cover of the oscillator?

Thanks,
Jon
