I would have thought so Andrew but I am surethe fun will start closer to November.

Not sure where the techs are today, I have only heard them on the GRN.
They still must be having problems with the comms in general though, Wollongong Comms has a terrible echo, must be really distracting for the operators if they can hear it

Pommy Lee was at Merimbula (Station 395) early this morning and I assume he would have done Eden (286) then probably over the mountain to Bombala then on to Cooma (but you know what they say about assumptions)?

Yeah I've been hearing that and what's weird is that it sounds like P25 'feedback' (or more accurately 'audio loop-back') where you get an echo rather than a squeal due to the time lag in DSP?

But if they're still 100% analogue it can't be that?

I must have missed them doing Merimbula and Eden, bugger it
Anyway I heard Bombala pumper doing a radio check this afternoon and they said they were testing the new radio that had been put in earlier today so I think you a right or close enough with you assumptions
The echo didn't seem so bad all the time, sort of comes and goes.The female operator didn't seem as bad but that could be a conincidence

An interesting thing is happening in the ACT with multi-select ...

An ACTESA comcen console currently has the ACTFB, ACTSES & ACTRFS talkgroups (old Type II GRN) all multi-selected, what's interesting is that the ACTFB talkgroups are encrypted but comcen is broadcasting the same operator audio in the clear on the other two TGs simultaneously! How's that for secure? :lol:

They can hear it alright, they've been complaining about it for days! This seems to be related to the half-duplex function of the consoles where they can still hear incoming radio traffic even if they're transmitting, and of course they can also hear themselves (or other consoles) but it's usually only just audible?

However I was listening today and a pumper called over the top of them while they were transmitting and it came through almost as loud as the operator. For some reason the monitor audio seems way too loud and their own voice is doing the loop out to the network then coming back to the headset and causing this 'feedback' problem (which explains the time-lag)? I wonder if they've changed headsets recently and the new mics are too sensitive?

I'm a little disappointed...

Motorola guys are doing stations this morning which use the (old Type II) GRN (on TG 304 GOULB 1), heaps of new RIDs coming up but I've been waiting to see what happens on UniTrunker when there's an emergency button activation on a GRN radio... absolutely nothing, not even a "call"? :(

Andrew

Edit:

I've just been going through the UniTrunker logs and I think the network is actually reporting the EBAs over the control channel but UniTrunker may not be programmed to display them?

It seems to appear in the data log as "E1D0 I 32C unknown single OSW *** "

Has anyone caught an EBA on Pro96Com?

Andrew, you will see that data on trunk 88 but T88 will only work on the old analogue GRN. ive seen emergency button presses come up on T88(234T was the last one, caused a bit of the stir :) )

Richard, doesn't that present you with a bit of a problem with Station 428 (Queanbeyan)?

They are currently using the old (Type II) GRN but if there won't be any sites left on the 4.1 network after this weekend, and 428 can't use the P25 TGs yet, how will they have comms?

It seems this post got way off topic but the FB fireground channel was not listed in the previous list posted on page 2 so here it is.
425.5875 - st 218.1
I have heard this from a fire 2 kilometres away using a external base aerial so it does depend on the terrain & your setup.

That's because it's a list of NSWRFS Fireground channels, I don't think anybody ask for the NSWFB Fireground channels or I would've posted them as well?
