Initial Test

Observing polarity, attach 12 VDC to the unit using the supplied power cable, inserting the plug into J1.

Using a frequency counter or oscilloscope, verify an output of 49.380 MHz ± 247 Hz.

A transceiver tuned to 49.380 MHz or VHF radio tuned to the 3
rd
harmonic of 148.140 MHz may also
be used to verify operation.
Using the XG50

Prior to initial use, power the XG50 for 8 hours. This should only be done once and while not required
for normal operation, will help minimize oscillator drift. When using the XG50 as part of the KX3
Extended Temperature Compensation Procedure, locate it away from the radio, in an area free from
drafts and heat sources. This will help minimize frequency drift during the procedure. A 3’ (1 M) 50
ohm patch cable may be used to connect the output of the XG50 to the KX3.
