Background

Wiki: SINCGARS

Since the U.S. discovered during W.W.II that HF radio (3 - 30 MHz) can skip around the Earth allowing eavsdropping, the main military tactical radio band is the VHF Low band of 30 to 88 MHz.  In Viet Nam the PRC-25 and it's successor the PRC-77 were back pack squad radios.  Both of these radios use the 150 Hz tone during transmit and then need to hear the 150 Hz tone on receive to open the squelch.  This makes them targets for squelch capture jamming.  The PRC-68 Family of hand held squad radios have about the same performance as the PRC-25 or PRC-77 and do not have tone squelch, but do transmit the tone for compatibility.  Another problem with conventional single channel radios is the they can be located by direction finding.

Voice encryption was handled on the PRC-77 by the KY-38 digital NESTOR Secure Voice System and later the VINSON system with the KY-57.  The PRC-77, and all the modern military VHF low band radios use a 25 kHz channel spacing (while commercial radios use 5 kHz) in order to support digital 16 kbps encryption of voice or data.  The KY-57 VINSON Secure Voice System is a separate box as was the KY-38.  The first SINCGARS radios (RT-1439) were designed (J5)  to support the use of an external KY-57 for voice encryption.

The next generation squad radio was designed to overcome these difficulties and at the same time to have operational modes that are compatible with the PRC-77.  The Single Channel Ground and Airborne Radio System (SINCGARS) is a radio system that supports frequency hopping or normal fixed frequency use.  When in frequency hopping mode the radio is a like other squad radios in that it can either talk or listen, but not both at the same time.

If the Transmission Security Key (TSK) used in the SINCGARS is the same as used in a KY-57 connected to a PRC-77 then they should be able to communicate.  This should also apply to the KYV-2 on a PRC-68.

The Portable manpack version is called the PRC-119(). All the other versions are either Airborne or Vehicle (land or water).

Note the Maintenance Kit needed for vehicle mounting is defined in SB 11-131-2.  This almost 300 page manual mainly lists the contents of the Maintenance Kits used for SINCGARS installations in about all kinds of military vehicles with wheels, tracks or propellers.  I have added bookmarks to make finding stuff easier.

The SINCGARS MTBF is about 5,000 hours, more than 10 times better than the VRC-12 & PC-77 MTBFs.  SINCGARS includes Bilt In Test (BIT) to help determine which module needs to be replaced.

RT-1439/VRC

Frequency hopping radio covering 30 to 87.975 MHz in 2,320 channels.  uses an external KY-57 for Transmission Encryption.  Can use either the MX-18290 or the MX-10579 to load the hop sets (Select 1 to 13) and the Transmission Security Key (TSK) (T1 to T3).  The hop sets define which frequencies will be used and the TSK supplies the key for the pseudo random generator that chooses which frequency to transmit or receive.  For voice security (COMSEC) an external KY-57 is needed which requires a different key loader.

This version, and maybe all of them, has two receive modes, tone squelch and open squelch.  The problem with tone squelch in an FM radio operating on a single fixed channel is that an enemy can "squelch capture" the receiver and make inoperable.  A check for this is to switch to the open squelch mode and if the radio is quiet, then it's being jammed with a CW carrier.  This mode of jamming is a problem for the PRC-25, PRC-77, and the VRC-12 Series of vehicle radios.  It may be that the frequency hopping of the SINCGARS radios is the answer to this type of jamming, but when a SINCGARS radio is used in the fixed single channel mode it still is susceptible to CW jamming.

There is an external speaker that can be added to the SINCGARS receiver that provides noise squelch so that stations not transmitting the 150 Hz squelch tone can be copied.

RT-1523 (RT-1702?)

Adds Integrated COMSEC (ICOM) so an external KY-57 is no longer needed.  Now a separate Transmission Encryption Key (TEK) is needed and a separate key loader.  This could be one of the standard key loaders used for the KY-57 such as the KYK-13 (Electronic Key Device) KOI-18 (Tape Reader), KYX-15 (Net Control Device), KYK-13 or the latest AN/CYZ-10 Data Transfer Device (aka ANCD) that holds all the keys needed for the SINCGARS and other Standard Operation Instructions (SOI).

Note that the RT-1523A and maybe later radios will not work at all when the KY-57 board has been removed.  But the no change RT-1523 does work with the board removed.  This may just need a jumper to fix or may require different processor ROMs.

Batteries

PRC-119 & Battery

Main

The main Battery is the BA-5590 carried in the CY-8523() Battery Box.  The BA-5590 can be replaced by any of the Bx-x90 series of primary or secondary batteries.
6160-01-284-4200 CY-8523A/PRC (80063) A3018381-1
6160-01-304-2034 CY-8323B/PRC, (80063) A3132600-1
This battery box holds 1 each BA-5590 battery and connects both sides in parallel for a nominal 12 Volts to power the radio.  The Battery box also has a pair of telephone type push terminals to support Radio Wire Integration by means of audio tones.

The Hold Up Battery is the BA-5372 which is a 6 Volt LiMnO2 chemistry battery with the tip Negative.

HRCRD (Handheld Remote Control Radio Device) Handset C-12493/U

Close up of HRCRD . HRCRD Showing the 2 connectorsThis microphone has one U-229 type connector and one 6 pin Bendix MS3116F10-6P connector.  It also has an LCD and some navigation buttons.  TM-11-5820-890-10-6 "Operator's Pocket Guide For SINCGARS ICOM Ground Radios". 

There must be a nice digital interface to the ICOM SINCGARS radios allowing remote control, and probably other functions.
Must be used with the CY-8523C Battery Box.

GPS Have Quick Time Of Day (TOD) Cable

Marked 01365/91001A0027 in center, GPS TOD on the MC329G2 (6 pin version of the U-229) connector end and RT-1319 on the 35 socket connector end.  The GPS TOD would come from a PLGR.  The Have Quick radios cover the aircraft bands of 108-115.975 MHz and 225 to 400 MHz with frequency hopping opertion.  These are very similar to the SINCGARS radios in that they need an accurate Time Of Day as part of their frequency hopping system.
The tag has:
NSN: 6150-01-375-8665, CAGE: 13499, P/N: 4260141040

I'm not sure if this cable will also work with the SINCGARS radios.  But the SINCGARS radios also use the PLGR GPS receiver for TOD.

The RT-1319 Connector is a Bendix-9137 JMS27467T15B35S  1467830 only two sockets are installed.

Pacer Speak  The family includes the GRC-206, the AN/PRC-113 manpack( 116-150 & 225-400 MHz), the AN/TRC-176 transportable, and the AN/VRC-83 vehicle-mounted radios.

The unified, micro-computer based set control of the RT- 1319 receiver/transmitter allows 4 radios to be controlled from 1 central radio. Through a fiber optics link, remote control is possible at up to 1.8 nm (2 mi;3.3 km).

These radios integrate High Frequency (HF)/Single Sideband (SSB)-both Upper Sideband and Lower Sideband (USB and LSB), Very High Frequency (VHF)/Ultra High Frequency (UHF)-Amplitude Modulation (AM) and VHF-Frequency Modulation (FM) communications. In addition to the channel presets, a guard channel is designed in. Optional Electronic Counter-Counter Measures (ECCM) and Communication Security (COMSEC) capabilities are also available.

GRC-206(V)1 can be fitted with KY-57 or KY-65 COMSEC devices; GRC-206(V)2 cannot.

I'm guessing the MAX232 is there to convert RS-232 from the computer to TTL for the radio.
Also that DB-25 pin 9 is a +5VDC power supply.
Pins 15 & 17 are data clocks so synchronous data is probably supported.
DB-25f  - 4'- box - 10' - PCI-329S (6-pin U-229) (DATA/AUDIO on SINCGARS)
The box has J1 MIC which is a GC-283 (6-pin U-183) connector and a VOICE/DATA toggle switch (4P2T).
The DB-25f connector goes to J1/J2 COMS on the computer (may require +5VDC on pin 9).

The PCB contains a MAX232CPE RS-232 to TTL converter and a 74HC123 Dual Flip-Flop.

A related item is the Military MVC-5000 Sony digital camera and PSC-6 interface unit.  The interface allows sending photos over phone lines, and might also work with radios.

Handheld Radio

There is now a handheld version of the SICGARS, but since there is no nomenclature it looks as if ITT has not yet sold it to the military.

Data Modes

The SINCGARS radios support both analog data (like a fax or modem) as well as digital data (like the UGC-74 RTTY machine, or computer serial coms).  See the U-229 Functions web page for more info.

Manuals

This is a list taken from an eBay acution saving me some typing, but I haven't reconciled it with my list.  A quick look at my list shows that these are maybe 1/2 of the SINCGARS manuals.

TM-11-5895-1412-12&P (pdf) Basic Generation Unit, AN/GYK-33 (NSN: 5895-01-260-4545) "The BGU is an automated management system designed to meet a critical requirement for a decentralized and automated system to generate print, store, and electronically transfer both single channel and frequency hopping CEOI information. BGU will generate and load frequency hopping information for radios and the Transmission Security (TRANSEC) Key (TSK) for ECCM protection. The BGU is intended to be more responsive to rapidly changing and highly mobile battlefield conditions as an integral subsystem of SINCGARS, High Frequency (HF), Very High Frequency (VHF) AM/FM, and Ultra High Frequency (UHF) radio systems."

voice encryption using pulse amplitude modulation and purmutations (maybe KY-38?)
Calls 1920 to 1950 patents:
1369805 SECRET COMMUNICATION SYSTEM, BAXTER P HAMILTON (AT&T), Mar 1 1921, 380/40 ; 333/28R
audio sub-bands are either sent normally or amplified thus distorting the sound
2089639 INTELLIGENCE TRANSMISSION, A. V. BEDFORD (RCA), Aug 1937, 348/480 ; 332/115; 348/725; 348/E7.027 -
a large number of newer patents call this one.  audio is sampled at  7 kHz and time mixed with a TV video signal
2313209 COMMUNICATION SYSTEM, G. VALENSI, Mar 9 1943, 370/214 ; 370/273; 370/533; 370/534; 380/33 -
only a small number of amplitudes are needed for speech so two channels can be combined
2364210 METHOD AND APPARATUS FOE SCRAMBLING SIGNALS, G. GUANELLA (Patelhold), Dec 5 1944, 380/35 ; 380/39
Prior art 1 where frequency bands are shifted do not alter the energy rhythm nor frequency change points and a skilled listener can understand.
Prior art 2 where segments are time shifted suffers from vowels being understandable allowing words to be guessed.
The new method combines the two prior methods.
2401464 PRIVACY SYSTEM, Roy Clinton Corderman (AT&T),  Jun 4 1946,  380/35 ; 379/194; 379/395; 380/36
Prior art frequency inversion can be understood by treating it as a foreign language, i.e. learning the new sounds.
Speech is time divided into two paths.
2401888 CRYPTOGRAPHIC COMMUNICATIONS SYSTEM, James Ernest Smith (RCA),  Jun 11 1946,  380/22 ; 360/15; 360/24; 360/8; 380/243 -
audio, fax, etc. signal is broken down into 50 to 100 ms long elements that are rearranged in the time domain.
2403280 SECRET TELEGRAPH SYSTEM, R. M. HICKS (Teleregister Corp), Jul 2 1946, 380/260 -
divides up the message and sends it over multiple lines
2406349 SECRET SIGNALING, Frederick G. Buhrendorf (Bell Labs), Aug 27, 1946, 380/36 ; 380/22 -
time slices are delayed.  More combinations than prior art systems
