DMR Do’s, Dont’s & Best Practices

On this page you will find information on how the most popular talk groups are set up and how to properly utilize each one of these talk group on the PALS DMR Repeater(s).

 

Each talk group on the world wide DMR network has specific uses on the system. Some talk groups are “always-on” and are active all the time on a repeater, and some are “user activated” and are only active for a certain amount of time if someone keys up their radio on that particular talk group. With hundreds of repeaters and thousands of users, there needs to be some “traffic control” rules in place to make sure the network runs smooth and efficiently. If all the talk groups were active all the time on all the repeaters in the world, I’m sure you can imagine what kind of mess that would turn out to be. That’s why there are Calling Channel Talk Groups and User Activated Talk Groups.

A talk group can be set up to be an “always-on” talk group or a “user activated” talk group. An always-on talk group is exactly that, it is always on and available on the PALS DMR repeater. A user activated talk group is always available but is not activated on the repeater until a user “turns it on.”  This is done by selecting the talk group and pushing your radio’s push-to-talk button.  The short transmission from your radio activates the talk group for a certain amount of time, usually 15 minutes. This “user activated” talk group will remain active as long as there is local activity on the talk group. After 15 minutes of local inactivity, the talk group goes dormant and back to a “user activated” status until it is activated again. Let’s take a look at all the talk groups that are available on the PALS DMR Repeater System and what each ones use is intended for.

  • LOCAL 9 – Time Slot 1. This talk group is for local Peoria/Bloomington area traffic and QSO’s. If you are going to talk to someone that is located in the Peoria or Bloomington/Normal area and you both can hit the PALS DMR repeater, then Local 9 is the place for you to be. That way, you do not tie up another talk group that may have multiple repeaters coming up at the same time. There is no need to tie up multiple repeaters on the network when both of you are in the same area and can hit the same repeater. This way your local conversation stays local and only ties up one repeater.

  • LOCAL 1 – Time Slot 1. This talk group is active all the time on the PALS DMR Repeater and is “always-on” on all of the Chicagoland C-Bridge connected repeaters. When LOCAL 1 is being used, your conversation is being broadcast on every Chicagoland C-Bridge connected repeater on time slot 1. Good for short statewide and regional communications. Not intended for long QSO’s.

  • LOCAL 2 – Time Slot 2. This talk group is active all the time on the PALS DMR Repeater and is “always-on” on all of the Chicagoland C-Bridge connected repeaters. Good for statewide or regional communications. It is also the primary talk group for the Chicagoland area. You will hear many people who live in the Chicago, IL area use this talk group every single day.

  • ILLINOIS 1 –  Time Slot 1. This talk group is active all the time on the PALS DMR Repeater and is “always-on” on all of the Chicagoland C-Bridge connected repeaters in the state of Illinois. When ILLINOIS 1 is being used, your conversation is being broadcast on every Chicagoland C-Bridge connected repeater on time slot 1. Good for short statewide communications. Not intended for long QSO’s.

  • MIDWEST – Time Slot 2. This talk group is active all the time on the PALS DMR Repeater and is “always-on” on all of the Chicagoland C-Bridge connected repeaters in the Midwest. Intended for short communications. Not intended for long QSO’s. It is primarily a call channel. Contact your party and move to a “user activated” talk group where rag chew is more appropriate.

  • NORTH AMERICA – Time Slot 2. This talk group is a “user activated” talk group and is on a 15 minute PTT timer on the PALS DMR Repeater. It is “always-on” on most all DMR repeaters across North America. This talk group is for general QSO’s spanning across multiple North American repeaters. Due to the wide reach of the NOAM talk group, we kindly ask that hams respect the fact that this talk group is distributed all across the country and that they keep conversations to a reasonable length and take regular pauses to accommodate others that might want to join the QSO. Remember, if you feel that your conversation is going to be lengthy in nature, it would be a good idea to take that conversation to a “user activated” talk group such as a TAC channel talk group or the UA-English talk group.
