VKDMR Talkgroups as of June 2023.

Expanding on this:

• Talkgroup 505 on timeslot 2 is the nationwide call channel. Every repeater in Australia listens on this talkgroup.
• TG 9 on timeslot 1 is the complete reverse – it is linked nowhere. Use TG 9 for “sh!t$ and giggles” local repeater use.
• Sitting in-between are all the “User Activated” talkgroups. Remember that all talkgroups on VKDMR are located on timeslot 1 except for 505 and the parrot.
• To User Activate a TG, someone has to dial up the TG number on EACH REPEATER to be linked and then PTT their radio on that TG (for around 3 seconds) Dialling up the TG alone is not enough. You must PTT once there for about three seconds to hook up a repeater to the TG and there is no audio or visual confirmation on your radio of success. Then, users on the other side of the QSO on their local repeaters have to do the same thing. Links will time out after 15 minutes of inactivity after which the whole procedure needs to be re-started.
• There are no other formal “static” or permanently linked talkgroups except a few randoms that individual repeater owners have set up.
• Assuming you’re not driving, operating heavy machinery or even just going for a walk, you can observe the behaviour of the network at what is commonly referred to as The Dashboard.
