Anyone have good knowledge on how this works, whats involved in the subscriber units (other than clicking on the box) and how well it works?

Ah... Shuffle band plan.

1) ASK is required I believe for the feature
2) It allows the system admin to renumber or reorder the channel assignments. So lets say the controller says goto channel 7B1. The radio see's 7B1 and goes oh, that's really 7C1.
3) You have to know the entire shuffle plan to be able to make it work.
4) Motorola Astro25 series feature (probably works on APX too) only. I do not believe your Astro subscriber units can support this.
5) I doubt any other manufacturers will support this feature.

It's a real cheapish way to make it harder for people to monitor using cloned radios or scanners which would just give you the audio on whatever frequency 7B1 equates to.

Sounds like another Motorola way of keeping other vendors radios off their PROPRIETARY radio system. Sounds
like an end run around the P25 standard. Let us see what happens with time. The Feds are already buying a ton
of the E F Johnson portable and mobile radios. They saw the light.

No it doesn't .

Here is what Motorola has to say about it:

"Shuffled Band Plan
Radios that have been upgraded to be Rebanding capable are also capable of supporting the Shuffled Band Plan. The Shuffled band plan is intended to help prevent unauthorized system monitoring and access on Shuffled Band Plan enabled systems. Shuffled Band Plan shuffles all trunking numbered-channels allowed in the band plan.
Note that Shuffled Band Plan can only be enabled by the Rebanding Capable CPS program with an appropriate Advanced System Key per Trunking System. This feature is designed and implemented for Motorola 3600 Type II Trunking systems"

According to the patent that describes the invention, there's no shuffling involved; channel number -> frequency correlations are just inverted (i.e. channel 1 is somewhere around 860.9875 and channel 750 or whatever it is is at 851.0125).

As far as I can tell, there's not even an option in the CPS to input a custom map.

correct, available on type II Smartnet/Smartzone analog
MTS2000/MCS2000 support this feature with rebanding firmware.
