Simoco P25 Question

[youngn]

For such radios as the SRP9180 which is an Xmode capable radio (Analogue, analogue trunking, P25, P25 trunking etc) does the entire radio need to be programmed purely as a P25 radio to use it for any P25 channels or can you set it up to change the mode depending on what is programmed into each channel??

For example:

Ch1 Analogue xxx.xxx MHz
Ch2 P25 xxx.xxxMHz
Ch3 P25 xxx.xxxMHz
Ch4 Analogue xxx.xxxMHz

Cheers,

Good question youngn. I'm keen to know the answer myself, was looking at getting one also.
My hypothesis is that you can program the channels for singular analogue and singular digital as you have demonstrated above, but obviously not for trunking + conventional/digital single channels.

Now i'll wait for somebody to come in and prove me completely wrong, haha.

one would imagine you could if you had the option board installed onto the radio at the time, the P25 Option does not come standard with the SRM9000 Series unfortunately.

Mathew they are capable of Multi Mode how ever you would have to switch modes to achieve this for example

Personality 1 - Conventional
Personality 2 - MPT1437

so you couldn't have a conventional channel in a MPT1437 Personality hope this helps

Phil,

Do you know what is needed to make these radios do P25? I cannot find any information on it!

from what im reading you will need to have the MA-MAB-2 (Multi-purpose Application Board kit) installed prior to being able to do P25 then it will allow you to have up up 40 Zones with 250 P25 channels

I just read and extracted this from a document about the SRM series:
"P25 option board upgrade (Rev 9 and later) ------- MA-P25KIT1"

I did some research on the SIB board and from the programming software it seems to have control of audio more than anything else, there were options for various audio levels and also a scrambler I think. So still not sure what it's for.

You will also need a trunking bandplan for the service involved. Good luck in getting that.

Already got Fleetcoms UHF, Fleetcoms VHF, SMR and Victrunk which came with the software
