5. 5. The SPU-7 intercommunications set (ISC) is a signal distribution system de-signed to provide internal crew communication, airwave transmission via the R-863, R-828, YaDRO-1A radio sets, monitoring of ADF code ID signals, as well as transmission of signals from the audio warning system and radar altimeter. SPU-7 components: amplifier distribution unit control boxes for pilot and copilot located to the left and right of the circuit breaker consoles, respectively control box in the troop commander station in the cargo cabin, (MIC) switch three additional ICS tie-in points 1. crew chief station; 2. winch operator station; 3. tail gunner station; (MIC) switch on the right triangular panel (ICS RADIO Press to talk (PTT) Button) buttons on the pilot and copilot cyclic control stick circuit breaker on the right circuit breaker panel SPU-7 INTERCOMMUNICATIONS SET (ICS)
6. 6. SPU-7 control panel: 1 (MASTER) and (MONITOR) volume control knobs to set volume of internal and external comms.; 2 rotary selector to select source to monitor: (UHF) R-863 UHF/VHF radio set (HF) YaDRO-1A radio set (VHF) R-828 UHF radio set (NF) not utilized (I think it is a redundant SW Radio Switch) (ADF) ARK-9 ADF set (SAR) ARK-UD VHF homing set 3 - (NET 1-2) - not utilized 4 (ALL CALL) button for transmission of emergency messages. When pressed, inter-phone signal is transmitted to all ICS station at doubled volume level, audio warning messages are transmitted with maximum volume level; 5 - (ICS-RADIO) selects communication via ICS or the selected radio.
7. 7. Pilots ICS Controls. The pilots SPU-7 ICS control box is located to the left of the cockpit's forward overhead panels.The ICS-RADIO keying button on the cyclic allows the pilot to transmit over the selected intercom net or the selected radio without removing his hands from the controls. When the APK (ADF monitor) switch on the R- 863 radio control panel is set to the ON (up) position, the ADF signals are routed to the pilots headset regardless of the position of the ICS-RADIO switch on the SPU-7 control panel. Transmissions from the emergency receiver in the R-863 radio set, the RV-3 radar altimeter ground proximity warning signal, and the audio warning set signals are also routed to the pilots headset regardless of the ICS-RADIO switch position. Copilot's ICS Controls. The copilots SPU-7 ICS control box is located to the right of the cockpit's forward overhead panels. A MIC switch is located on the right triangular panel. There is an ICS- RADIO keying button on the copilots cyclic that operates in the same manner as the pilots keying button. The RV-3 radar altimeter ground proximity warning signal is routed to the copilots headset regardless of the ICS-RADIO switch position.

14. 14. Radio Procedures Default freqs UH-1H VHF 116.00 Used for Air to Air among different airframes & ATC Calls FM 30.00 Air to Air within a flight UHF 251.00 B/U Air to Air or Air to Air among different flights of Hueys MI-17 R863 UHF/VHF 116.00 Air to Air among different airframes & ATC Calls JADRO HF 02000.0 Very Long range Air to Air & Air to Ground R828 Ch. 1 Air to Air & Air to Ground KA-50 R-800 VHF116.00 Air to Air among different airframes & ATC Calls R828 Ch. 1 Air to Air & Air to Ground Flight lead & the AMC can assign different radio freqs as required. Example: We have a mission with 10 aircraft, 2 MI17s & 8 UH-1hs. 4 of the Hueys are transports, they will talk among themselves on the FM on 30.00. The other 4 Hueys are gunships. The are going to form two different flights. Gunship flight A will communicate among themselves on 32.00 and gunship flight B can communicate on 34.00 If the two gunship flights want to communicate with each other without interfering with other aircraft they could use their own UHF freq of 253.00 or even share a UHF freq with the other Hueys. If any of the Hueys wanted to talk to the MI17s they would have use the VHF radio, IE 116.00. All aircraft will use VHF 116.00 for ATC/CTAF or general flight calls to all aircraft. This is just one example of how to use different radios and freqs to communicate effectively during a mission while keeping confusion and noise to a minimum during a mission.
