I've seen 11676 coming up and testing TDMA slots on 003-004 Mt Ainslie. Also RIDs in 1054nnn range. Perhaps a test talk group?


Parked Unitrunker and DSD on the Castle Hill site 001-075 yesterday while i was out and managed to capture a couple of GRN techs (RID 2920XXX) carrying out TDMA testing in the late afternoon using TG 11677 and what appeared to be external call testing

So in the transition to Phase 2 TDMA this will be the channel display on Unitrunker for 001-075. (On a big site like GPT Sydney CBD you would be looking at close to 70 frequency enteries).
There were no hits on my log for the second time slot on the control channel and backup control channel

420.1750 = 05-0028 P1 Voice Channel
420.6750 = 05-0108 P1 Voice Channel
421.4250 = 05-0228 P1 Voice Channel
421.6750 = 05-0268 P1 Backup Control Channel
421.9250 = 05-0308 P1 Voice Channel
422.4250 = 05-0388 P1 Control Channel
423.1750 = 05-0508 P1 Voice Channel
423.4250 = 05-0548 P1 Voice Channel
423.9250 = 05-0628 P1 Voice Channel
420.1750 = 07-0028 P2 Voice Channel 1
420.1750 = 07-0029 P2 Voice Channel 2
420.6750 = 07-0108 P2 Voice Channel 1
420.6750 = 07-0109 P2 Voice Channel 2
421.4250 = 07-0228 P2 Voice Channel 1
421.4250 = 07-0229 P2 Voice Channel 2
421.9250 = 07-0308 P2 Voice Channel 1
421.9250 = 07-0309 P2 Voice Channel 2
423.1750 = 07-0508 P2 Voice Channel 1
423.1750 = 07-0509 P2 Voice Channel 2
423.4250 = 07-0548 P2 Voice Channel 1
423.4250 = 07-0549 P2 Voice Channel 2
423.9250 = 07-0628 P2 Voice Channel 1
423.9250 = 07-0629 P2 Voice Channel 2

on DSD the TDMA P2 channel is displayed as "420.175-1" or "420.175-2" etc

Control channels are FDMA only (at the moment) so the concept of a slot doesn’t apply. The TIA is working on a TDMA CC variant, but don’t expect to see it any time soon.

A CC is just FDMA, so there is no first or second or any other slot.

Is this from the latest RFS radios now being circulated?
I heard that the VRA have now been taken under the auspices of the NSWRFS for radio calls

"I heard that the VRA have now been taken under the auspices of the NSWRFS for radio calls"

In general, no. Local arrangements only, for example Central Coast RFS (ie Gosford / Wyong) are taking calls for Central Coast VRA (General Land Rescue) on the local RFS talkgroup (it think it ends up on Cental Dispatch usually) . However the compatibility is there.

Folk may want to comment if they know of other VRA units on RFS control.

Same goes with Dubbo VRA on the Orana RFS channel, and Wagga Wagga VRA on the Riverina RFS channel.

Noticed the VRA being tasked via the Central Coast RFS channels from around November/December last year. Was definitely confusing at first.

Anyone know why the VRA don’t run their call outs via the SES and their Ops channel? I thought the SES operators had direct access to the police rescue coordinator via the ‘batphone’, which would be essential for timely rescue callouts, something I didn’t think the RFS have access too?
