This was taken from the Hawaii DMR NET Topic for today and I wanted to share for anyone interested.


When we’re using our digital radios with repeaters, reflectors, and talkgroups, it’s important to keep a few things in mind:

All the repeaters, reflectors, and talkgroups are shared resources. In order for other hams to link to, identify themselves as being on the resource, or unlink from it, it’s necessary for there to be a gap in the transmissions. When you’re having a longer chat, it’s good form to pause for a few seconds between transmissions to give other hams a chance to access the resource. If you transmit back and forth rapidly on one of the busy shared resources, you’re going to frustrate other hams!

If you’re on a much used DMR talkgroup, like 3100, and you want to have a longer chat, consider moving to one of the TAC channels where ragchewing is allowed (313 – 319) to continue your chat.

TAC channels should not be used as primary calling channels. In the U.S., the TAC channels (talkgroups 310 – 319) can’t be added as static talkgroups, and also won’t become auto-static. If you want a primary calling channel, try something like the U.S. Wide talkgroup, 3100. For more information, see the BrandMeister U.S. WikiOpen in new tab regular.

There can be a slight delay after pressing PTT before the transmission initiates. It’s a good idea to wait a full second (say “one-one-thousand”) before starting to speak so that the beginning of your transmission doesn’t get cut off. (TEXT TAKEN FROM AMATEUR RADIO NOTES)
