Well I for one appreciate what you bring to the forum Richard, I have to say I'm just as interested in the technology as listening to what's broadcast over it (if not more so)!

I put a LOT of time into this forum with the lists I maintain and I do hope to get something back from it, so I am very thankful for your input.

Thanks Andrew- and I do appreciate the amount of work you guys do. Putting together the data you have takes serious hard work. Hopefully if we can all continue to work together to help people better understand what this all means & how things actually work we will all be better off.

Cheers,

Richard

On a different note, did anyone else notice that control channel encryption was removed from the P25 specifications?

What a good change that was!!

[ivahri]

Not sure how that relates to the subject but...

Whether it is "removed" from the Standards or not it is a feature available now. P25 is a standard that defines certain parameters & features but allows manufacturers latitude to add further features so long as it doesn't conflict with those that are defined. Encryption of the trunking control channels is in the class of features that can be included by vendors as an option.

Time will tell if it comes to NSW. I personally hope it does even if that upsets people here. The option if it doesn't happen is Phase II or TETRA, either of these is TDMA & with limitations that will cost the NSW taxpayer even more money.

Cheers,

There would be advantages of encrypting the control channel such as making it even harder for illegal radios to make their way onto the grn...

I don't work for a govt agency anymore but i'd imagine it would still be very easy with the right equipment and know how to put an illegal radio on any EMS talkgroup and cause havoc...

If it was not for the wanker element i'd say the government would have no need to look at these types of options, but while there are idiots out there essentially playing with people's lives they need to do whatever it takes to make sure it does not happen...

I can say for sure I do enjoy what you do have to post Richard, as it adds a new dimension to scanning and having an understanding of how things work...

[Longreach]

yeah bit harder than turning up with a XTS5k with FPP and hoping for the best. only so far that you can go. youll get caught eventually, most likely in a blue singlet

Heard the test too between ACT and NSW on Friday on D307. it sounded good. im guessing this is a cross border thing?
