Description
This National XCU-50 Crystal Calibrator, is made for the HRO-50 & HRO-60 Receivers.
This one looks to be in great shape.
I do not have a receiver to test it in but these calibrators are reliable and is a simple circuit.
It is being sold as is, as described for the family of a silent key who was my friend.
