Maintenance RF-Orchestra!™ Transmitter Installation and Operation
6-14 6880493G02-C July 2000
The typical control command patterns are for network traffic.
If the ReFLEX25 station is operating with heavy traffic and does not dekey, the RFCQ 1 trace
will not show any control commands. Trace data is created only during a dekey and key cycle.
Note: To verify remotely that the RF-O! transmitter is transmitting, enable the Wattmeter debug
trace through RFO FIPS: a 192 SPCQ 64. While keyed, the wattmeter readings will be read
approximately once every 2 seconds. Disable the debug trace with the RFO FIPS: a 193 SPCQ
64 command.
If no data is present during the RFCQ trace, the problem may be the plug-and-play cable
(connected to J4 on both the RF-B! transmitter controller and RF-O! transmitter backplane).
If data is present during the RFCQ trace, verify that AM and FM control commands are
present and alternating in a voice page pattern; this can be accomplished by examining the
modulator number, m# (1=FM, 2=AM) in each row of data.
Verify that the Sync and SCI data are not being lost. Sync and SCI data is sent in 0.125 st
increments. The st field is the Sync and SCI time slot represented in hexadecimal in units of
tenths of microseconds past 1 second, modulo 1 second. Ensure that all time slots are being

RFCQ
Field
Description
f: Frequency change 0 if same as last center frequency, 1 if new center frequency needed.
st: Displays the start time for this transmission.
f: Displays the center frequency index for this transmission.
o#:
Displays the subchannel offset (location relative to center freq) for each modulator. Its value is
meaningless if m# = 0.
m#: Displays the type of data for each modulator for this transmission (0=idle, 1=FM, 2=AM).
