Hi everyone,


I am located in central Auckland, and many years ago I used to enjoy listening to Auckland Police radio. Unfortunately for me, many years ago the police moved from analogue to Encrypted Digital P25 here in Auckland (as well as Wellington & Christchurch), making it now impossible to listen in to local events. 


But.... fortunately for me, both Whangarei and Hamilton districts are still using analogue radio, and I can still enjoy listening into both those from my home location, in Auckland.


Yesterday afternoon, the Whangarei channels stopped working (at least in the northern Auckland area), and I became suspicious that they might have been turned off due to a move to P25 Encrypted Digital.


I searched the Internet to see if there was any information, but I was unable to find out anything regarding the timeline for other districts going digital, or the cause of yesterdays outage. All I could glean was that work is currently in progress in upgrading the whole emergency communications network, including fire and ambulance, but no definite dates etc.


Fortunately, for me, the Whangerai analogue channels are working once again... but for how long?


So, my questions are...


1 Does anyone know when the Hamilton and Whangarei districts will retire their respective old analogue radio networks?


2 Regarding yesterdays outage, which lasted several hours, was that a technical fault, or was it in some way connected with a forthcoming switch off of the analogue network?


All, and any information gratefully received.

what time did it stop yesterday?

 

there was a major power cut last night for the Brynderwyn hill so a transmitter may have stopped.

I didn't pay attention to the exact time... very roughly mid afternoon, around 3 or 4pm from memory.

Loss of Brenderwyn might very well account for the outage.

Appreciate the info.

thats to early to be related to that power cut but there has been power lines down around the aera, especially waipu. one of those may have fed the transmitter.

There's a thing called the PSN which will join up all the emergency services. It includes cellular, digital radio and paging.

 

 

 

More info here: https://ngcc.govt.nz/

 

 

The Public Safety Network Programme is aiming to start transitioning agencies to Priority Cellular services in mid-2023 and Digital Land Mobile Radio in 2024.

Vaguely related, but when they were first introduced Motorola P25 radios were notorious for their awful UI which made it extremely easy to send in the clear when thinking you were sending encrypted. So the comms may not be encrypted, just digital instead of analog.

I believe all emergency services are going P25 encrypted by the end of the year, but more likely to be middle of next year I suspect depending on timings.

So it may be wasted effort trying to pick up any other regions.

Much appreciate the effort in finding the information.
