[TheList] Trunktracking in NZ

Thu Jun 11 06:38:59 AEST 2009

If you want a voting scanner, your best bet is to buy a tait 2 way radio
in the correct band and program it to receive only. With the move to
digital I expect you will start to see quite a few Tait 2020's appearing
on trademe.

Phil..

No sorry, the police do not use trunking on the system they use
now...voting is different to trunking..

The NEW P25 system is trunking and of course encrypted. So it may be
possible to follow the trunk side by not hear any voice.

Trunk radios use what's called  a control channel (data information)
this channel tells the radio to go to a voice channel when 

required. When the voice channel is finished the radio goes back to the
control channel and waits for further instructions..

This means the channel used for voice is free for another call from
another group...So it's quite possible to have a hundred radios share

20 or more channels...the channels not dedicated to any one radio or
group..all radios on that system sit on the one data channel and 

listen for a request to go to a voice channel when required.

I don't know of any scanner that can Vote per say...

Hi Shane,

I know in the past you have told me about the Voting system the Police
use.
Is this the same as trunktracking?

If I buy a uniden scanner with Trunktracking3, can I program all the
police south frequencies in it, and it will decide which frequency to
use?

Thanks,
Phil.

Hi Phil,

Did I not answer this one for you a little while ago..

Apart from the talked about version the police are using..

Three types are used here that I know of.

Smartzone by Motorola (this one is tracked by the Unidens automatically)

Edacs appears to have a full North Island system in place also I believe
now owned by Telecom can be tracked with a Uniden

MPT 1327 used Nation Wide by Telecom don't know of any scanners setup to
follow this..  This is known as Fleetlink or Teamtalk

depending on when you got to know the system and Telecom's buy in.

Hi there,

Just wandering, how is Trunk tracking used in New Zealand?

Is it used at all and who by?

Thanks,
Phil.
