APCO P-25 vs. Mototrbo

#1 Post by Avidlistner » 10 May 2014 19:36

In my listening area we do not have much in the way of P-25 or Mototrbo (everything is analog right now as far as I know), so I am not familiar. What is the difference? Can a P-25 radio and a Mototrbo radio communicate with each other?

Yes - in Analog Mode

The two different protocols can't communicate with one another digitally, which I believe is the question being asked. As Bill states though, if both are in analog they could potentially, were they each programmed with the proper data.

Hi Scott, yes that was what I was curious about. I did have a conversation with a radio manufacturer that said he was not familiar with MotoTrbo, (thought that was odd) but anyway, if all public safety has to become P-25 compliant and it cannot communicate with MotoTrbo, why would anyone in their right mind spend all that money to go to MotoTrbo, unless they are being sold a bill of goods that its accepted? I thought the whole point of making everyone go to P-25 was interoperability?

MotoTrbo is not intended at all for PS. It is a low cost digital alternative for business and industrial users. Hams like the built in ip connect linking features so some of them prefer it over P25.

There's no mandate that all public safety has to go P25. Having several local agencies in the same band (VHF vs. UHF vs. Low band, etc) would be a far greater benefit to interoperabilty than going to P25.

There was/might still be, plenty of Federal Grants that stated "Radios must be P25 compatible" to be approved for the grant

Mandated or not very few will make it through the next phase of rebanding without digital audio. 6.25KHz of bandwidth isn't going sound very good in analog.
