I assume from your username that you're talking abou Victoria Police? The digital network is up and running, however it is being retransmitted on the old analogue network while a few digital coverage issues are worked out. The full digital changeover could be anywhere up tok a few months away.

hey yeah sorry i am from VIctoria Melbourne, now will they be the same numbers as on analogue? or totally different numbers? What is a digital scanner worth these days? is it better on digital more clear? why the change?

P.s Do you remember the yellow Vl turbo police cars? If so did you drive them? your thoughts? Are there any fine examples still out there with members (your friends) who might have bought it after its duty and still have it? Any pics apart from the ones on the net?

Once digital is in, it will be encrypted, won't be able to be listened to (in theory).

The boundries fo rthe diffeerent channels remain the same, but, for instance, Channel 69 becomes Channel 5 Zone 2.

Not really sure it will happen.
When trunking radios came out, it took a few years for someone to work out a computer program to listen to it. My first "trunk tracker" in 1996 ran on DOS and needed two scanners. It was then developed by the large American companies to get it into the hand held scanners we have today. They also needed the market to sell it to pay off the cost of development, and that is the USA, plus many other countries.

However, unlike Australia, it is illegal in the USA to listen to encrypted communications, so they have no legal market. This is the same in many other countries. With this the big developers being Uniden and Radio Shack have no intention to develop this technolgy since they can't sell it.

It may happen, but it maybe a long time too.

Not only is it a matter of the equipment being readily available, the digital encryption technology is virtually impossible to crack, and there are safeguards in place to maintain the security of the system even if someone does manage to crack the key.

Tasmania went digital ages ago. And it's still possible to listen providing you have a trunk tracker.

The DES system that NSWP will be using is crackable. You just need a lot of computer power and time. It could be done comerically, but as the large communication companies such as Uniden and Radio Shack are bounded by their market being the US, there will be no legal development. There was an article in a Comms mag about 4 years ago about the CIA taking up to 6months to crack encrypted radio comms.

When trunking took off here in the mid 1990's, everyone in radio world said that it won't be cracked. Within 6 months, an Australian had developed the first trunk tracker program on DOS. All you needed was a PC and two scanners.

Thanks Johnboy, good to hear hopefully it will get cracked and we can listen to the interesting stuff that goes on. I love sitting at home on a cold night listening to the police scanner.

Hopefully you aren't admitting to an offence of wanting to crack an encrypted network.

If you want to listen to a police radio, go become a copper.

The reason the encryption is needed far outweighs the curiousity factor of scanner jockeys

Discussion of cracking encrypted police radio systems really isn't what this forum is for.
