Mutual Aid Talkgroups
All public safety TMR units share eight Mutual Aid talkgroups. Mutual Aid
allows direct communications with various agencies on one repeater. This
decreases the chances of receiving a busy tone at an incident.
Permission is required to use a Mutual Aid talkgroup:
1) Contact your provincial dispatch point for assignment of a Mutual
Aid talkgroup: Shubie Radio, Emergency Health Services (EHS), and
Royal Canadian Mounted Police (RCMP).
2) Advise the dispatcher of who is to be noti fi ed of the talkgroup
assignment (be sure you receive a radio check from each party you
have requested to join).
Shared Simplex Channels
• All public safety agencies that use TMR have three shared simplex
channels.
• Simplex is only reliable for roughly 1 to 2 km.
• Permission is not required when using the simplex channels but a
person must
fi rst voice-call on the desired channel to verify if anyone
in the area is using that channel.
Simplex All 1, Simplex All 2 and Simplex All 3
SX All 1 - International Calling Channel (ICALL)
SX All 2 - National Working Channel (ITAC-1)
SX All 3 - National Working Channel (ITAC-2)
The ICALL channel shall be used to contact other users in the Region for
the purpose of requesting incident related information and assistance.
If necessary, the calling party will be asked to move to one of the ITAC
channels for continuing incident operations or other interoperability
communication needs.
