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.
a
Set up RT C and D for FH operation
Make sure FCTN is at SQ ON for both RT.
b
Set RT C MODE to FH and KY-57 MODE to C
Contact RT A with RT C.
c
Set RT D MODE to FH and KY-57 MODE to C
Contact RT B with RT D.
d
If RT A is the NCS, set RT D MODE to FH-M. If RT B is the NCS, set RT C MODE to FH-M.
e
Connect the retransmit cable (See illustration, page 4-20); then set RT C and D FCTN switches to RXMT The
retransmit station is now ready
RT A can contact RT B.
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.
a
Set up RT C and D Set up one for operation on SC net’s frequency; set up the other for FH operation on FH net’s
hopset.
b
Contact SC net outstations using SC retransmit RT Confirm communications.
c
Contact FH net NCS using FH retransmit RT Confirm communications.
d
Connect retransmit cable (See illustration, page 4-20).
e
Set RT C and D FCTN switches to RXMT The retransmit station is now ready.
f
Contact RT B with RT A Confirm communication.
