Set Rx=Tx, so most Rx parameters track Tx: [?]
1=Off 2=On

1. Use Custom Sweep to narrow the sweep range to avoid the false lock, but be careful not to narrow
it too much so it avoids the true carrier lock as well. DO NOT increase the sweep range, as this will
guarantee to bring false locks within the Demod sweep.
2. Preferably, adjust the Rx IF Frequency to account for the true Rx carrier frequency (including
offsets), then adjust the sweep range to 50% of the `Normal` value. This will allow the Demod to
re-acquire the carrier (even with further minor variations in Rx carrier frequency) without it sweeping
into a false lock. If you are attempting to do this, when you have the Demod correctly locked you
can read the current value of offset frequency from the `Demodulator Detailed Status` screen in
order to adjust the Rx IF frequency.
6.7.15 Change, Rx, Demod’ AUPC Menu
This screen provides the option to enable or disable the “Remote Reporting” facility used with AUPC to
enable a distant end modem to report it's Eb/No and BER back to the other end of the satellite link. The
facility can be either On or Off. See AUPC in section 8.11.1 on page 154.
6.7.16 Change, Rx, ESC/AUX/BA Menu
See Change, Tx/Rx, Modulator, ESC/Aux/BA Menu on page 76
6.7.17 Change, Rx, RX=TX Menu
This is described in detail under the initial note on the Rx=Tx function in para 6.7 on page 86
OFF The receive path operates fully independently from the Tx path
ON Many of the Rx parameters follow the Tx, which greatly simplifies the configuration
for duplex links. When enabled only the Insert Mux timeslot selection, Rx Clocking
& Buffer Size, and IF Frequency & Sweep control require setting independently
of the Tx path.
Note: Temporarily setting Rx=Tx is a convenient way of copying the Tx configuration to the Rx as when
disabled again the Rx path keeps the Tx values, and does not return to the old Rx values.
