Part 1 – Introduction
The purpose of this document is to set out the terms and conditions under which organizations involved in search and rescue (SAR) operations in Canada may be authorized to share Industry Canada’s national simplex VHF radiocommunication channel (149.080 MHz). This channel will be referred to as the SAR-IF channel (Search and Rescue Interagency Frequency).
The use of this channel will be to facilitate interagency radiocommunications during SAR operations where no other practical means exist. The frequency may also be used for SAR exercises, with prior notice to Industry Canada. The channel is not, however, intended to create or replace existing radiocommunications networks used by agencies, teams, or units for internal communications. SAR organizations making use of this frequency should be aware that while Industry Canada will take measures to minimize potential interference to SAR operations on this frequency, Industry Canada cannot guarantee that interference will not occur during actual SAR operations or when exercises are being conducted. The SAR users will accept this possibility.
Part 2 – Authorization Process
SAR agencies or individuals seeking authority to use this channel will be required to apply to Industry Canada for a new licence, or to amend their existing licence by adding this frequency to their current complement of radio frequency channels. Additional fees are required when this frequency is added to a base station licence. No additional fees are applicable when adding this frequency to existing mobile licences. Footnote 1
- The departments/agencies listed at Annex “A” may apply directly to Industry Canada for use of the SAR-IF national simplex VHF radiocommunication channel (149.080 MHz), through the normal application process.
- Those organizations listed in Annex “B”, and any other entities not listed in either Annex, that are interested in applying to Industry Canada for use of the SAR-IF channel must first obtain a letter of endorsement from their respective sponsoring organization, certifying the need for access to the SAR-IF channel.
While this frequency may be deployed in maritime and aeronautical situations (see Part 3, Licence Conditions for conditions), agencies doing so must be aware that the authority for this frequency is not included with maritime and aeronautical authorizations associated with the vessel or aircraft. Additional land mobile licensing is required.
Applications should be submitted to the appropriate Industry Canada District Office.
Part 3 – Licence Conditions
Notification for SAR Exercises.
In the case of planned exercises by the SAR community that might involve use of 149.080 MHz by participants, particularly in areas where Industry Canada maintains active base stations operating on 149.080 MHz, the provincial/territorial Ground Search and Rescue Council of Canada (GSARCC) representative, or designate, must advise the appropriate Industry Canada District Office 48 hours in advance of such exercises.
Aeronautical Use Within the Canada/US Coordination Zone.
Use of this frequency in aircraft is permissible on an itinerant basis, subject to the normal constraints imposed by Transport Canada with respect to the approval of the installation of radiocommunication equipment on board aircraft. Within the Canada/US Coordination Zone, use by aircraft is restricted to those times when the aircraft is operating below 1000’ above ground level (AGL). Footnote 2 The Coordination Zone is broadly defined as those Canadian lands and waters lying within 120 km of the United States border.
Configuration, Interoperability and Encryption.
The SAR-IF should be configured for narrowband FM modulation (11K0F3EJN) as a standard practice; particularly within urban areas and the Canada/US Coordination Zone.
If, however, the provincial/territorial search and rescue authority determines that wideband FM modulation (16K0F3EJN) is more likely to facilitate interoperability within its jurisdiction, a wideband configuration is permitted for the SAR-IF. This decision should be communicated to all current and potential SAR-IF users in the jurisdiction. Prior consultation with the appropriate Industry Canada Regional Office is strongly advised.
Radios equipped with a Continuous Tone-Coded Squelch System (CTCSS) must be set to a CTCSS tone of 156.7 Hz when transmitting and receiving on the SAR-IF channel. The SAR-IF channel shall not be used in an encryption mode unless all authorized users during a particular operation are in possession of the required equipment to monitor the transmission.
Users are also reminded that the VHF simplex frequency 149.080 MHz is analog, and therefore transmissions are not secure. General radiotelephone operating procedures outlined in RIC-22 (noted below) must be followed by all users, including standard phraseology and calling procedures, and use of the phonetic alphabet.
Other Applicable Standards and Specifications.

International distress frequency
Radio frequency designated for emergency communication
An international distress frequency is a radio frequency that is designated for emergency communication by international agreement.
For much of the 20th century, 500 kHz was the primary international distress frequency. Its use has been phased out in favor of the Global Maritime Distress Safety System.
Use of some distress frequencies is permitted for calling other stations to establish contact, whereupon the stations move to another frequency. Such channels are known as distress, safety and calling frequencies.
Satellite processing from all 121.5 or 243 MHz locators has been discontinued. Since February 1, 2009, the U.S. Coast Guard only monitors distress signals from emergency position indicating radio beacons (EPIRBs) that broadcast using digital 406 MHz signals. Digital 406 MHz models became the only ones approved for use in both commercial and recreational watercraft worldwide on January 1, 2007.
Maritime Mobile Service frequencies
International distress frequencies, currently in use are:
- 2182 kHz for medium range maritime voice use. The US Coast Guard has said "beginning August 1st, 2013 the Coast Guard would no longer monitor 2182 kHz". Many other MRCCs, for example most in Northern Europe, now only have MF capabilities and no HF.
- Several HF maritime voice frequencies exist for long-distance distress calls:
- 4125 kHz
- 6215 kHz
- 8291 kHz
- 12290 kHz
- 16420 kHz
- Marine VHF radioChannel 16 (156.8 MHz) for short range maritime use
- 406 MHz to 406.1 MHz is used by the Cospas-Sarsat international satellite-based search and rescue (SAR) distress alert detection and information distribution system
Digital selective calling frequencies
Several maritime frequencies are used for digital selective calling (DSC), and they are also monitored for DSC distress signals:
- 2.1875 MHz
- 4.2075 MHz
- 6.312 MHz
- 8.4145 MHz
- 12.577 MHz
- 16.8045 MHz
- 156.525 MHz, Marine VHF radio Channel 70
Search And Rescue frequencies
- 123.1 MHz: Aeronautical Auxiliary Frequency (International voice for coordinated SAR operations).
- 138.78 MHz— U.S. military voice SAR on-the-scene use. This frequency is also used for direction finding (DF).

- GMRS: 462.675 MHz is a UHF mobile distress and road information calling frequency allocated to the General Mobile Radio Service and used throughout Alaska and Canada for emergency communications; sometimes referred to as "Orange Dot" by some transceiver manufacturers who associated a frequency with a color-code for ease of channel coordination, until the creation of the Family Radio Service, in 1996, "GMRS 675" or Channel 6/20 on mobile radios today. Its bandwidth can vary between 12.5, 25 and 50 kHz, and is also allocated to Ch. 20 on 22-channel FRS/GMRS "blister pack" radios. It can have a repeater input frequency of 467.675 MHz, and a tone squelch of 141.3 Hz. After FCC deregulation of simplex FRS/GMRS radios, FRS users may transmit up to 2 watts on the GMRS emergency channel 20 (462.675 MHz) with 141.3 Hz CTCSS, or channel 20-22.
