Firmware Version Number
The firmware version number of the MFJ-5124 can be read using the analog
meter on the MFJ-991/993/994 auto tuners via the interface cable. To obtain the
firmware version number, place jumper JP1 on the “A” position, jumper JP2 on
the “C” position, and then turn on the radio’s power. After the initial bouncing
of both needles on the auto tuner, the reflected needle will bounce repetitively
with approximately five seconds pause between intervals. The number of
bounces within each interval indicates the version number. For example, two
bounces of the reflected needle represent firmware version number 2.
