RPM costs about 2500 dollars.
Just FYI.
Every talkgroup must be individually set to NO TX and no calls.
And, be SURE that emergency functions are disabled. Particularly and especially the emergency button. (Button assignment menu)
In power up options, auto login must be disabled.
As for a logical ID, on a radio that doesn't auto login (won't affiliate) and doesn't have a single TX
enabled talkgroup, it doesn't even matter. Pick a number.
EDACS takes IDs up to 16382, I think.
Odds are that the highest numbers, near the max, are not in use. But don't get TOO close to the limit.
I'd say 16,300 and above are PROBABLY not used by any assigned radio.
Please be aware that if your radio DOES transmit into the system without authorization, you can get
in a LOT of legal trouble. LOTS of it.
As a matter of personal operational security, when your program is finally set up and working to your satisfaction,
remove the Revision menu from the radio so that no worthless, nosy suckup from the fire department can find your programmed ID
and report it in hopes that it'll make brown nose points with somebody in the radio management division.
As long as your radio BEHAVES like a scanner, being totally unable to transmit, you're OK and no law says otherwise.
Trying to find an ID that's not in use has a certain logic to it. Duped IDs can be bad if the "legitimate" user of that ID tries to send
or receive a private call.
There's also always the slight chance that the system polls to see what radios are active, too. If it polls your ID number, and two
radios respond, that can cause interest.
Unfortunately I know of no way short of disabling the transmitter which can keep the system from stunning your radio if the command
to stun (or remote monitor) your radio is sent by somebody who knows your LID.
So you keep your LID secret and accept the possibility that no matter what you do, some day your radio may be unresponsive and
stunned. In which case you just reprogram it with a different randomly chosen ID. You'll be good again for an undetermined period of time.
You need to create your trunked frequency sets with CORRECT site ID numbers.
You need to create your talkgroup sets.
You need to connect them together in the system setup screen.
Start simple by creating a conventional channel set and hooking it up in the system setup screen.
Then save the file. It won't let you save a non-workable file.
Check out your radio's system/talkgroup capacity and be aware of it while creating your file.
If your radio has, for example, 128 talkgroup capacity, you have to know that every selectable
talkgroup in the radio counts toward the 128 group capacity EVEN if the same talkgroup is repeated
in different systems.
As an example, I created a talkgroup list of 40 talkgroups which represents a combined talkgroup list fo ror a specific agency,
regardless of what site I'm listening to. It's a master list I made rather than go to the extra effort of making a customized list
of talkgroups for EACH of the four sites in the system.
Since they never re-use a talkgroup number for a different purpose on a different site, there was and
advantage to just creating a single master talkgroup list and connecting it to each site's trunked channel list as four separate systems.
Those 40 talkgroups on 4 systems count as 160 talkgroups.
I could probably save some talkgroups by making custom lists for each site individually, and deleting,
for example, the north site only talkgroups from the east, west, and south site talkgroup lists.
But I choose not to do that as I have plenty of talkgroup capacity in my radios and it's easier to manage
a smaller number of talkgroup lists. (My main radios has 65,535 talkgroup capacity.)
If you don't know your radio's talkgroup capacity, you can view it if your radio has the features menu enabled.
If the features menu is enabled, it'd have to be reprogrammed first, with the features menu turned on.
Be aware, very few shops will program system info into your radio unless you have a letter of
authorization from a responsible authority allowing you to get this done.
