sent in sequence in both the Sync and SCI pattern and when interleaved with the AM control
commands. If any time slots are being dropped, the problem still exists with the RF-B!
transmitter controller.
If data is scrolling across the screen, check the following parameters in the RF-O! transmitter:
RFO FIPS: r 902
RFO FIPS: RR 902 5
(1PPS window size is 5)
RFO FIPS: r 2049
RFO FIPS: RR 2049 0
(Simulcast launch offset must be in the range 0 to 4800)
If these parameters are outside of their normal operating range, set them to their default
values and reset the OCM. (Note: Parameter 902, 1PPS window size, is not writable with
RF-O! transmitter software version 1.4.0 or greater)
Check RF Power Path
To verify the power path, check each step in the RF power path:
