Figure C-2. SATCOM Programming Menu 3. Dedicated UHF SATCOM Operational Steps a. To operate in dedicated UHF SATCOM mode, connect a medium or high gain SATCOM antenna to VHF-HI/UHF J8 antenna connector with a coax cable. Analyze terrain in planned areas of operation for satellite look-angle access. Verify the SATCOM antenna is correctly oriented using a magnetic compass to point the antenna on the proper horizontal azimuth to the satellite. Make an approximate antenna vertical elevation adjustment. Pointing graphs and look-angle calculation software may assist in this task. Azimuths from these graphs are not adjusted for local magnetic declination. Table C-5 contains UHF satellite positions. To check SATCOM antenna C-5
pointing using the SATCOM receive signal strength indicator (RSSI) test, complete the following procedures: C-6 Table C-5. UHF Satellite Positions Footprint Name Satellite Position CONUS 100 and 105 dog W longitude LANT 15 and 23 dog W longitude IO 72 and 72. dog E longitude PAC 172 and 177 dog E longitude Note: The SATCOM RSSI test can be conducted only by using data operating parameters of 1200 or 2400 bps. Preselect data operation using KG-84 or ANDVT at one of these rates before initiating the test. (1) After placing the AN/PRC-117F into normal mode dedicated SATCOM operation, press the CALL button on the KDU. (2) Press ENT to initiate the SATCOM RSSI test. (3) Watch display for test completion. A relative signal strength score is displayed with a value from 000 to 100. Repeat test and adjust pointing of the SATCOM antenna to obtain a better than 80 score. (4) Press CLR to exit SATCOM RSSI test. b. Perform the following procedure for dedicated UHF SATCOM operation: (1) Rotate function switch to cipher text (CT) or TD. The AN/PRC-117F does not allow plain text (PT) non-secure voice operation in SATCOM to operate in a non-secure SATCOM mode. The radio defaults to DATA only operation when PT is selected. (2) After the radio initializes, press MODE. (3) At the OPERATIONAL MODE prompt, select NORMAL; press ENT. (4) Select the desired SATCOM net preset by pressing the PRE + or – switch. (5) Begin radio operation. See Figure C-3 for SATCOM operational displays. 4. SATCOM 181B Data Operation Using KG-84 COMSEC and Continuous Phase Modulation a. When using a SATCOM net preset using KG-84 COMSEC and Continuous Phase Modulation (CPM) modulation, the sender transmitting station decides in which CPM data option to conduct the transmission. The receiving end must also use a CPM data code of the same channel type. To change the data option code for the currently selected SATCOM net preset— (1) Press the circular arrow key to view the data option page of the SATCOM net preset. See Figure C-3 for SATCOM displays. (2) Use left/right arrow key to scroll over to data option field. With the up/down arrow key, select the required code. Only the data option codes relating to the presently selected COMSEC mode and/or satellite channel type can be selected.
