Signals from the waveguide switches

b. Signals from the waveguide switches are

K4 is energized for the antenna position and DS10 is off

and DS11 is on. For the C-band/K-band operating

applied to K4; these signals indicate the positions of the

mode of AN/GRC-144(V)4, when both waveguide

waveguide switches (para 2-80). Output signals from

switches are in the same band position, relay K4 is

K4 are routed through 1A15A18E27 and E28 to

energized and DS10 is lighted and DS11 is off. If both

WAVEGUIDE SW indicator (DS10 green and DS11 red)

switches are not in the same band position, relay K4 is

at meter panel 1A15A8. For AN/GRC-144(V)3 and the

not energized, DS10 is off and DS11 is on.

K-band only operating mode of AN/GRC-144(V)4, relay
