Re: TR7 on CW


 

Yep, I'm working on a T-4XB right now that has no output of the CO and control of that goes through at least two switch wafers.

V1.2 and V1.3 are giving me fits. they should be 1.6 and 4.2V, respectively and they're at 6.4 and 7.2. The crystal tests good. Resistors around the circuit are within tolerances, so I'm not sure if the DC voltage I'm reading is just due to the lack of oscillation or not.

That being said - is there a standard for labeling switch wafers? I

Is "A" generally closest to the panel? Or farthest? Please pardon
