Warning - There are satellites constantly monitoring 121.5 243.0 and 406 MHz and are designed to pick up the feeble signals from these survival radios. DO NOT Transmit on these frequencies unless you want to be visited by SAR personnel.General Information
Radio has been used as a way to call for help for many years. Although now discontinued 500 kHz was the international distress calling frequency for ships at sea. In modern times satellites monitor 121.5, 243 and 406 MHz. The early satellite systems gave a position, but the newer 406 MHz beacons transmit digital data about what kind of ship or plane is in trouble and possibly a GPS based location.
In the case of someone behind or near enemy lines there is a problem with rescue radios that work in the clear. The enemy may hunt the survivor by direction finding his beacon. The enemy may capture a beacon transmitter and use it to lure a rescue team into a trap. In all other cases these problems do not exist.
In some cases, like a pilot ejecting from a jet, you want the emergency beacon to turn on automatically. In other cases you want the survivor to turn on the beacon when they decide that's the thing to do.
SARSATIn the beginning they used Doppler to locate emergency beacons on 121.5 and 243 MHz. This service is scheduled to end next year on 1 Feb 2009. The current service is based on transmitters operating on 406.025 MHz using digital data including a transmitter serial number.
Will there still be a requirement for mil aircraft to have a "guard channel" at 243 Mhz? What about civilian aircraft guarding 121.5 MHz?
ArgosArgos is a unique worldwide location and data collection system dedicated to studying and protecting the environment. It's based on polar orbiting satellites and uses transmitters on 401.650 MHz that send digital data including a transmitter serial number. Mainly used for animals and environmental data like ocean buoys but also for expeditions and yacht racers. Based on the French Space Agency CNES. Animal transmitters are made by Sirtrack and others.

MoviesIn the movie "Behind Enemy Lines" there a scene where the hero goes back to where the ejection seat landed and he gimmicks the beacon radio. But in reality the beacon radio stays with the guy on the parachute, it does not follow the seat.

PRC-90-2 Rescue Radio with 90BAv3 battery adapter
These radios are part of the bail out kit that aircrew members carry. It is turned on by the user, not automatically like the URT-33.PRC-96 Navy Lifeboat Survival Radio
The improved PRC-90-2 survival transceiver is familiar to most military aviators as the rugged, hand-held survival radio that has saved the lives of thousands of downed pilots and crew members. It has voice and beacon capability on the military distress frequency of 243.0 with voice Tx and Rx only on 282.8 MHz. 282.2 MHz is used by the Civil Air Patrol for ground - air coms with military aircraft during SAR operations.
The PRC-106 is a derivative of the PRC-90-2 and provides both beacon and voice Tx/Rx capability on the civil and military distress frequencies of 121.5 and 243.0 MHz, but does not have the 282.2 MHz channel.
The PRC-103 and PRC-195 are other derivatives of the PRC-90.

PRC-112This unit replaced the PRC-90. It is a synthesized radio that covers 225 to 400 MHz and has a transponder function to help rescuers locate the radio. My guess is that when the location mode is turned on the radio turns on and off at a rate depending on how far it is from the rescue aircraft giving the aircraft range to radio.
The civilian and military have gone to the 406 MHz digital rescue radios that are supported by the SARSAT system.
The PRC-112 transmits the digital signal at 406.028 MHz. (SARSAT Report 708-1)
Major components to the AN/AYD-1 Personnel Locator System (PLS).
The PRC-112 has two fixed channels assigned to 121.5 and 243 MHz that can be used in either beacon mode or AM voice mode.
- SARSAT system.
- The KY-913/PRC-112 program loader loads the
- PRC-112 with frequency of operation (225 to 300 MHz) and a personal ID number (actually the SARSAT data set).
- The AN/ARS-6(V) is the aircraft system that interoperates with the PRC-112 giving the pilot either bearing or bearing and distance to the survivor.
- TS-4360 Test Set
It too uses a specialized BA-5312/U 3.4 AH battery instead of commonly available batteries, but there is an official battery adapter being developed by the government.
There are a large number of variations on the PRC-112. The later ones have a built in GPS receiver to allow reporting position. The design constraints for the PRC-112 are different than for a civilian survival radio in that the PRC-112 probably will be used behind or near enemy lines.
I doubt that the AN/ARS-6(V) can be used with civilian 406 MHz beacons.
If the PRC-112 is sending a SARSAT compliant digirtal message then it can be picked up by an enemy receiver, seems like a problem.

The URT-140 is the ejection seat beacon only version of the PRC-149.
Designed to run from a couple of "D" size 3.6V batteries. There have been a number of reports about battery venting, sparking, etc. that has resulted in the development of a very special battery just for this radio. Also there's a problem when the radio is carried loose in a bag where it can get turned on accidently. A lockout clip has been designed as an add on fix.

Normally turned on by the survivor, but optional kit to allows automatic operation when a lanyard is pulled, like in an ejection seat.
URT-33D/M Beacon Radio set (Ejection Seat)This is a Vietnam era survival beacon transmitter (it has no receive capability). Commonly used in conjunction with the SDU-5/E Strobe light.
Maybe featured in the movie "Behind Enemy Lines"?
Featured in the book "The Rescue of Alpha Foxtrot 586" by Andrew C.A. Jampoler (Navy Institute Press).
MIL-B-38401A 16 Feb 1965 discontinued 7 July 1992
For use with AN/ARA-50 or AN/ARC-34 aircraft receivers.
The rescue beacon will jam the frequency (121.5 or 243 MHz) so it's not usable for other purposes. Note the PRC-90 has an alternate channel for voice communications so can be used even if 243 is active with a beacon.
AntennaThere are two possible antennas. The built-in telescoping antenna or the external flexable antenna. Only one antenna can be used at a time.
The flexible antenna is deployed in ejection seats along with a lanyard that turns on the radio when the seat ejects.

LCDR Castle Rescue in Laos by Nail, Sandy & Pedro 28 Dec., 1970- "The URT-33 is presently not connected to the aircraft because the kits required for the installation are not available, but VA-L5 will not connect them up automatically anymore. Since we feel that the VC have a sufficient number of radios that they can use to home on the beacon. Additionally the beacon virtually eliminates use of 243.0 until it is shut off, and if evasion is immediate the URT-33 might not be deactivated, and this could easily reduce or eliminate the possibility of radio contact." eBay Photo - URT-33B eBay Photo -

CBD ad - The beacon is a first alert device that activates upon separation from a disabled aircraft, and transmits a swept tone signal at 243 MHz. Approximate dimensions are 4.8 X 2.5 X 1.2 inches. Opportunities for improved performance include: ability to transmit on 121.5 MHz (civil emergency), 243 MHz (military emergency), 245 MHz (training), and 406.025 MHz (COMPAS/SARSAT); ability to operate normally and unassisted during parachute descent and after touching down on land or water; features to impair an adversary's ability mimic its signal. Beacons should be reparable by a commercial source, compatible with existing means of activation (magnetic plug assembly or remote cable and switch assembly), and interface with existing parachute harnesses, survival vests, and survival kits

ProPublica: Adrift: How the Marine Corps Failed Squadron 242 - 12:11 video.
Part of an email to ProPublica
In the subject video at 6:21 "He can't get his radio to work. The Marine Corps hadn't set it to automatically transmit location."
The drawing of a radio has the look and feel of the PRC-112, but really does not match it. Can you tell me the model of this radio?
Can you tell me about the option "to automatically transmit location"? What would trigger that?
It's my understanding that all aircrew members are issued an emergency strobe light. The one for Vietnam, Korea . . . was the SDU-5/E. Here's my web page for it:
I have sold thousands of battery adapters for this light so the military battery is not needed.
The newer rescue strobe light is the MS-2000 that uses a couple of common AA batteries instead of a very specialized military battery. Can you tell me if this is still being issued since it would have saved Resilard.
At 7:41 "In the seat of every fighter jet, there's a location beacon. It's purpose is to send out location information so missing aircrew can be rescued. Resilard's beacon malfunctioned in the water, sending no signal. In at least two previous accidents, this model (URT-140) stopped working when submerged in water."
Classically the ejection seat radio was just a beacon with no location information. That's to say it just transmits a wailing audio signal on 121.5 MHz (civilian frequency) and 243 MHz (military frequency). Aircraft radios have a "guard channel" that monitors one or the other of these frequencies. Also the original SARSAT (Search and Rescue Satellite system) listened to both of these frequencies and could determine a rough location based on the Doppler shift. This system has a big advantage in that the beacon turns on the instant the ejection seat is triggered. That means any nearby aircraft that hears the signal and can look around to see the parachute and follow it as it descends. This was common practice in Vietnam.
Because of a plethora of false alarms in this system it was abandoned by SARSAT in 2009 and a new digital system was started. The 406 Mhz beacon has a stored serial number that allows looking up what vehicle it is registered to, a contact phone number and a provision for GPS coordinates and other stuff.
But . . . it's the nature of the Global Positioning System that a receiver can take up to 15 minutes (cold start) to acquire all the data needed in order to provide a fix. As far as I know the PRC-112 and URT-140 are not tied into the aircraft buss and so will need some time before they can transmit a location.
Gibson Girl SCR-578/CRT3 BC-778 & PRT-5This is a famous life boat rescue radio. Tx on 500khz and 8364 khz.

"Cospas-Sarsat is a satellite system designed to provide distress alert and location data to assist search and rescue (SAR) operations, using spacecraft and ground facilities to detect and locate the signals of distress beacons operating on 406 Megahertz (MHz) or 121.5 MHz. The position of the distress and other related information is forwarded by the responsible Cospas-Sarsat Mission Control Center (MCC) to the appropriate SAR authorities. Its objective is to support all organizations in the world with responsibility for SAR operations, whether at sea, in the air or on land."
Users of the 121.5/243 MHz beacons will have until 2009 to complete the switch over to 406 MHz beacons.
Since 1982, more than 11,000 people have been rescued world wide with the assistance of the Cospas-Sarsat System.
Digital data beacon used in the CONUS -
ACR TerraFix 406 Beacon has 2 models one with and one without builtin GPS.
SDU-5/EThis is a personal strobe light typically carried by each aircrew member.
Can use my battery adapter instead of the BA-1574/U Mercury battery.
SDU-30This is a aircrewman distress marker light that uses a 3 Volt flashlight bulb and a special lens
Uses two each BA-1328/U batteries, can substuite two AA cells that have a modification.
For marking position or fratricide prevention
Note an IR light stick can be attached to a short parachute cord and spun overhead making a "buzz saw" that's very visible to searching aircraft.

There are a number of ways for a radio to work in a wilderness area, i.e. where there's no cell coverage, and most depend on satellite technology.
Today saw this video:
Jim Tweto C-180H Crash Alaska 16 June 2023, 9:04 - @ 1:03 it's mentioned that a Garmin InReach sent the SOS.
They are called Satellite emergency notification devices (Wiki).
In my opinion you need more than a beacon, that's to say you need to be able to have a two way conversation to let the rescue team know what the problem is and for you to get a confirmation that your SOS has been received. These devices have a much lower monthly cost than satellite telephones (Wiki).
