NOTE! RF tunings need to be done ONLY if any RF block component is replaced.

All RF tuning operations must be carried out in the MJ-15 Module Jig!
•
Power to MJ-15 must be supplied from an external DC power supply, not FPS-8
prommer
•
MJ-15 input voltages:
Maximum + 5 VDC
Nominal input for RF tunings is +4.2 V DC

Remember the cable attenuation when setting required RF levels
