STEP 2. Rotate selector control knob to move through available selections, or select numeric value using the (D/D) ↑ number switch to change the numeric value. STEP 3. Press ENTER (X/E) ↓ press the Enter switch to configure to radio. SATCOM-M01 Rx-CT-120 TK 01 FSK VINSN V16K CHANNEL NUMBER: 100 R295.975 T262.375 S/G M/Z D/D P/N X/E STEP 4. Begin communications.

1. Setting Up for DAMA Appendix G AN/WSC-3 At antenna controller, dial in the elevation and azimuth of satellite (such as, UHF follow-on 6) that the assigned channel is located. This setting depends on a ship’s location and it changes as the ship travels the ocean. There is an azimuth/elevation computation aid used to determine these values; each ship has one or more. a. Verify all power to the SA-2000 is on and all switches are turned on. b. On WSC-3 turn on or set as follows: (1) Turn power on. (2) Place standby/operate switch to operate. (3) Place control switch to local. (4) Place SATCOM/LOS switch to SATCOM. (5) Place modulation switch to EXT Modem. (6) For frequency select switches, dial the uplink frequency from Daily Comm Status message for the operational channel (for example, CONUS DAMA 1). (7) Completely turn power control knob clockwise, then turn back approximately one-quarter turn. (8) Partially extend radio from chassis. (a) Set SATCOM offset switch to offset 4. (This is the normal setting if the difference between uplink and downlink frequency is 41-MHz. Sometimes offset 3 is used if the difference is 33.6-MHz.) (b) This switch sets the downlink frequency in the radio. (c) Set TDMA/non-TDMA switch to TDMA position. (d) Return radio into chassis. c. At SB-4125 or SB-4126 IF patch panel, patch the TD-1271 Xmt to the transmitting radio. Patch the TD-1271 Rcv to the receiving radio. (Usually it is the same radio.) d. On the SB-4124 PATCH panel on the OK-454 or OK-455 equipment rack, ensure the TD-1271 XMT position is either normal thru’d or patched to the radio used to transmit. This TD-1271 XMT position is the top left position on the panel (A1J1). e. At the TD-1271. (1) Turn on the TD-1271. (2) Ensure the transmit inhibit switch is off. G-1
