Radio Scanning Frequencies & Information in Australia

The original poster said that the frequencies are between 505 and 515 MHz, so it is NOT the Motorola Zeon Digital Network (which is between 865.0125 and 869.9875 MHz). And while MOST Tetra networks are encrypted by default, it is apparently NOT a Mandatory requirement. However, having said that, it is true that there is currently NO scanner available that will monitor Tetra, encrypted, or otherwise.brisbanescan wrote:hi 415Tango,
Fantastic info you have provided at the moment the Motorola Zeon Digital Network is unlistenable as it is a digitally encrypted trunked network although the lower frequencies you provided for example 468.25 is a Special Events channel which today is being used for the QPS at the Big Day Out not alot of chat but enough to know where they are coming from
The radios being used are the Motorola MTP850, which is Motorola's most recent TETRA Portable Hand Held two way. It does say that they use the Zeon network, and I remember when I turned them on they would say "Zeon" on the screen with a blue circle. However, a mate of mine who was scanning during schoolies, said he heard me talking around the 505 MHz area, and these were the only radios we used the whole time.Comint wrote:Also, it would be interesting to know the Brand/Model No. of the radios being used, as there aren't many models that will handle both Tetra and Conventional in the same unit.

Well, the plot thickens.415Tango wrote:The radios being used are the Motorola MTP850, which is Motorola's most recent TETRA Portable Hand Held two way.

A Communications Bridge (also known by various other names), is basically some electronics that takes the received audio from one radio and feeds it to one or more other radios, and also has provision for keying the other radios.415Tango wrote:Wow. It amazes me how complicated these things are.
How would they have used a bridge to link systems together?
