[Repeater-Builder] FS-Motorola DES Key Loader

I have a Motorola DES Key Loader T3020AX which is surplus to my needs. This is the one built into the MX style radio case and has the HEX code pad. A very small portion of the upper right side of the keypad has become exposed, but still works well. I do not have any cables. It has a battery

Randy, I think the subject has been covered well enough already. Perhaps the best analogy would be a Hewlett-Packard power meter, where the sensor is matched to, and calibrated with, the meter itself. If the sensor should somehow be destroyed by accident, one could not simply purchase a new sens
