Forum Rules; please read!

Rules? Why?
As much as we enjoy open chatter, there are specific limitations which we'd like users to adhere to. Every forum contains users with bad attitudes, so this rule set has been put in place to keep users civil and keep the forum flowing smoothly. Any evasion or constant rule breaking may result in a warning or ban.

If you begin to do any of the following, stop typing:

• Use of racist, sexist, homophobic or hateful language.
• Harrasing and flaming other uses, regardless of who began what.
• Posting pornographic materials or linking to any related materials.
• Posting viruses, spyware or refferal sites in either topics or signatures, including links to them.
• Discussing illegal activites; including, but not limited to MDT decoding, "how-to" methods of decrypting encrypted frequencies, monitoring and discussing military and high-level law enforcement agency frequencies and monitoring mobile phones/cordless phones--also discussing frequencies you know you shouldn't listening to.
• Discussing security/related arrangements and information about high-profile events.
• Creating an alternate account to avoid a ban on a primary account. Both accounts will be deleted.
• Posting any member's real life information without permission of the user.
• Impersonating any staff member of the forum.
• Remaking a previously locked or deleted thread. Please contact a staff member if you have any issues in relation to a locked or deleted thread.

If you know you're listening to something you shouldn't be listening to, don't post on here about it.

If you do have any issues with a specific member or topic, please contact an administrator of the forum to resolve this issue.
Do not inflate the situation by posting topics about it.

Thanks and enjoy!

" ,,,, discussing and monitoring frequencies not listed on ACMA's database ... "

I am not sure that is a helpful description.

I am monitoring Wyong Shire Council's 5 channel MPT1327 on visits to the Central Coast and they are definitrly using at least 1 and possibly 2 frequencies that are not listed on the ACMA .... 488.7125 (ch 1 voice) if anybody from the ACMA is reading this

I think you might have to spell who is not to be discussed
There is a suprising anount of information on the internet for instance on Australian military radios eg the MBITR frequency-hopping radio that is using Type 1 encryption (which I think is higher than AES) in use by our services since the 2000 Olympics (see Thales website)
It also possible to glean a lot of information from magazines eg Austraian Defender (which I buy)
If you say no military frequencies (eg airforce, navy and army) and no high-level law enforcement users (eg elite elements of state police, federal agencies etc) might be a better description.
The other issue of course is that the new GRE.com PSR500/600 scanner decodes NAC in a split second .... I am compiling a fascinating list of NACS of the encrypted kind in both the 468Mhz band and elsewhere. It is only a matter of time before the GRE firmware includes Radio ID decoding (already available for trunking). According to what I have read in say Daniel's P25 primer, the NAC and RID are not in the encrypted part of the packet data burst - which is why GRE is able to develop software/firmware to read it.
All I am saying is monitoring encrypyted frequencies is not an illegal activity in this country (unlike the US)

The ACMA database is also notorious for accidentally deleting frequencies (or least moving them into the not for publication frequency listing) eg Channel 23 468.4000 NSW Police has been missing for many months. Yet alpha is still pumping out on it, albeit encrypted most of the time. Usually they reappear but not always.

I think maybe "no military frequencies (eg airforce, navy and army) and no high-level law enforcement users (eg elite elements of state police, federal agencies etc)" or similar description might be a more helpful way forward.

I agree 100% Grant...

Thanks for the feedback guys. As I said, it's still in the draft stage, and is open to all the feedback! I'll make several amendments shortly, as you've stuck some important points which I didn't think about before. I agree with your more specific description of the 'monitoring/discussing encrypted frequencies' section, I'll change this segment.

The rules were somewhat written quickly--and I'm not the best at writing rules either.

But yeah, thanks again. I'll make some changes shortly.

EDIT: Changes have been made. Let me know.

The other example I can think that you should probably prevent discussion of is security information / arrangements for the high profile cultural icons that bring people to Sydney .... two or three major ones I can think of .... all P25 users now. They are the obvious ones.
