Default M7300 "No affiliate scan"?

Looking to get clairfication... Is the M7300 capable of scanning a P25 system (Like the BK KNG P800) with out affiliating, or does it require programming similar to the Motorola no affiliate scan?

Thanks...

It's easy. Just turn off auto login and also uncheck the TX Enable box for every talkgroup in the radio except for those that you have a legitimate requirement to be able to transmit on. (Probably none...but maybe in your case.)

No need to transmit. Just monitor.

The instructions are the same. I use an M7300 myself, for monitoring every EDACS and P25 trunking system in the general area. Absolutely no issues.

And its for sure no affiliate? Not interested in causing issues with the local system...

Yep, no transmit if done correctly.

How I used to program radios for the News Media on PD & FD dispatch, and FD Fireground talkgroups.

The talkgroups were encrypted, but the local media was allowed to listen to them, but not the Tactical groups or Car-to-Car groups.

The local media (TV, newspaper, etc.) would purchase the radio, and bring to us to program. Even though it was a obscenely over priced and glorified scanner, I assigned a LID number to the radio, and had it active in our UAS Database. In this way, I could kill it if it ever became missing or stolen.

(FYI: Back in the early 2000's, I had the radio firmware changed to zeroize all the cryptographic codekeys in the radio, if it was disabled/killed over the system.)

Post Ghosting a radio

This seems to be the topic of the week. So, I grabbed some screen captures and made a quickie how-to guide.

How are you guys all getting the system keys to do this?

They aren't unless they are authorized to have the system keys. It's been said before that these radios can be programmed using older versions of RPM that were released before AAC was fully implemented, locking down the programming of P25T systems.

Just buy the new Uniden SDS100 scanner when it becomes available and don't worry about it any longer.

Motorola systems always require system keys.

Harris systems SOMETIMES require system keys but that's less a matter of the system than of the version of RPM you are using to program it.

The later versions are progressively more locked down. Access files are required to program SOME systems. Each later version restricts additional systems requiring those access files for programming those systems.

I have no direct experience with anything newer than RPM 10. I guess that RPM2 (RPM programming software 2, not RPM version 2, they're different things) has locked things down a lot more, replicating Motorola's system key model, functionally speaking.

It's why radio enthusiasts who like to listen with Harris equipment prefer to use the oldest version of programming software that allows them to program their radios. Upgrading to a newer version can lock out the ability to program the very systems they want to listen to.

A few items to add to ElroyJetson's posting:

  • RPM revision 10b07 is the last hobbyist friendly version.
  • Starting with RPM revision 11a, to listen to trunked systems required a system key in the form of AAC (Advanced Access Control)
  • Starting with RPM revision 11a, when it is installed it permanently alters your License Key File (.dslc), thereby preventing you from reverting to an earlier revision of software.
    • In the old days... You could de-install RPM (and Programmer too) and move up and down in revisions at will, whenever you needed. Harris took a very dim view of that, and starting with RPM R11, locked that down.
    • WORKAROUND: If you need to install RPM R11 or later, before you do, make an archive copy of your pre-R11 .dslc file. It you need to revert back to R10b07 or earlier, simply swap the .dslc file to the earlier version!
  • All revisions of RPM-2 are locked down. No workaround possible.






My humble 2 worth....

Does 10b07 do Phase II? And does it call home on the internet when you install it?
