Pulled the calibration book as several suggested. No clue as to the manufacturer.
The model is an LM-8 It's identified as a "Hetrodyne RF Meter and Crystal Calibrator Equipment" The serial number is 13. The rest of the book looks like any other book with a similar unit. It's not for sale. Tnx and 73, Dave N7RK _______________________________________________ Boatanchors mailing list [email protected] https://puck.nether.net/mailman/listinfo/boatanchors
