FH to FH. If possible, RT C and D should have all required FH data before being
taken to their site. RT A and C must have the same FH data. RT B and D must have
the same FH data. Hopset F1 (used by RT A and C) must be different from hopset
F2 (used by RT B and D). If the outstation does not have the retransmit FH data,
a retransmit RT will have to ERF the new FH data to the outstation.
Set up RT C and D for FH operation. Make sure FCTN is at SQ ON for both
Set RT C MODE to FH and COMSEC to CT or
Contact RT A with RT C.
Set RT D MODE to FH and COMSEC to CT or
Contact RT B with RT D.
If RT A is the NCS, set RT D MODE to
If RT B is the NCS, set RT
C MODE to
Connect the retransmit cable (see illustration, page 4-21); then set RT C and
D FCTN switches to RXMT. The retransmit station is now ready. RT A can con-
tact RT B.
(Note: RXMT radios may be set to either CT or
but RXMT operators can
hear transmissions only when RTs are set to CT.)
SC to FH retransmit operation (mixed mode). RT C and D should have all required
FH data before being taken to their site if possible.
Set up RT C and D. Set up one for operation on SC nets frequency; set up
the other for FH operation on FH nets hopset. Set retransmit RT COMSEC
Contact SC net outstations using SC retransmit RT. Confirm communications.
Contact FH net NCS using FH retransmit RT. Confirm communications.
Connect retransmit cable (see illustration, page 4-21).
Set RT C and D FCTN switches to RXMT. Both RXMT radios must be set to
for RXMT operations. The retransmit station is now ready.
Contact RT B with RT A. Confirm communication.
