North Coast Firecom covers up to Bundaberg which is and will remain analogue for the foreseeable future. I often hear this traffic on the SC channels. I wonder how this will that work with the mix of half and half. Will the encrypted signal be repeated clean further a field so they don't talk over each other ?

My guess is that they will keep the analogue channels they already have as a backup to the GWN, or use the analogue channels/GWN at the same time (e.g. metro area=GWN, boondocks=analogue).

Digital on analog that is going to sound good isn't it LOL

It has been done for years from multiple agencies in NSW and QLD, it doesn't sound as bad as you think, it is the other way around that doesn't sound good but is still audible

umm pretty sure that once the GWN is out there in the SE, the analogue freqs will be shut down.
Listen while you can.

yeah i guess that would be a lot worse

No doubt there'll be a grace period where everything is simulcast, but after that.........

I'm a little late to the thread but there will be a simulcast setup as an interim service incase of any issues but will be later switched off.

However it is said that some areas are likely to have a longer simulcast period for interoperability between areas that boarder digital and analogue. I guess only time will tell

For anyone interested here is the QFES Bandplan

Thanks for posting bagman.

Did you mean to post the first page (pic) twice...it would be good to see the page that has community safety etc info on it.

Nope I didn't that was my mistake, I have edited the post with the other talkgroups.

I scaled it down to make it forum friendly but if you want the full size images they are here (https://goo.gl/photos/2Xz75cqpq4smv9Jo7)

I also have the QFES GWN training info if you are interested in that

I believe there may be a 'typo' in the above QFES Bandplan under Operations Miscellaneous ->
NCCGR Interstate TG -> QPS, which shows D10-CLR.

All other D10s are QAS, and following the other patterns, I believe the QPS D10-CLR should be D9-CLR.

Also, going by Annex A to the NCCGR RALI GS-1, all the frequencies under Operations Miscellaneous are Simplex.

Yes the agency direct channels are digital simplex. When using that you can see the radio ID and GPS coordinates of the TX radio.

I find it odd that there are TG's for the COWs when they are designed to expand the network

Eg: COW deployed, each service uses its own dispatch or spec ops channels and the COW operates transparently. I don't know why there'd be TGs reserved for use on COWs only

Edit: also odd that the police don't have access to those talk groups

Yeah I thought it was odd that they are their own TG's but I guess if it is being used because of widespread damage it could be setup for a simplex expansion instead of temporarily filling in a blackspot.

The Interops channels will be the same across all agencies even SES even though they are not yet on the GWN rollout. The rumours are that they might be waiting 2 years before they are going digital.

As QPS and QAS will have their own TG's.

Thanks to Rooster I have started using Unitrunker to get an insight into the TG's being used on the GWN. I have labeled the known QFES TG's that line up with the posted bandplan

The biggest issue will be deciding who is the lead agency and who controls said interop channels. I've used them, but only for talking to the service they belonged to.

I can't read your screen shot. Just looks like read lines

SER switched analogue off today

[rapps_101]

Has the ambulance switched across yet for SER?

[rooster]

Gold Coast, Logan/Beenleigh and Ipswich (formerly voting groups 9,8 and 7 respectively) have gone over. Not sure if the others are going over before or after xmas.
