As long as the digital system is not encrypted the mode is legal under FCC Part 97 Amateur Radio Service rules. There is a limitation on what bands spread spectrum can be used on, 222 MHz and above, but there is no such limitation on digital voice modes.Does anyone know the legality of using Motorola TRBO technology on amateur radio, specifically in repeater operation on UHF 440-450 MHz? It appears that a new repeater using this mode is up and running in the NYC-Metro area.
I think you are referring to WB2HWW, correct? They just switched to TRBO, although I still hear some analog now again.
It's funny, I was just going to go remove the repeater from my scanlists when I saw this...
Interesting thread. In Ft. Worth Texas there is a P25 Amateur repeater so no, as Dave stated so long as the frequencies are coordinated there is no limitation as to which voice protocol can be used. Some Operators in Dallas are toying with the idea of creating an EADS Digital repeater as again, the audio is quite exceptional.
It's rumored that MOTOTRBO may become inter-operable with P25 in the future. While I'm no guru on TRBO I've heard some things TRBO does that no other flavor of Digital can do that makes it an interesting and unique product. It really could be to Amateur radio what DSTAR has failed to do.
Aha. Of course, because I have no TRBO equipment, I would have never been able to tell that. :lol: Thanks for clearing it up.Bezking,
Incorrect. WB2HWW is still, and will remain analog.
What you may be hearing, is that, on occasion, WB2HWW simulcasts the KC2CQR MotoTrbo
repeater. And I must add here that the Trbo system works flawlessly. It seems to be everything
that D-Star wanted to be, but isn't. The building penetration of the Trbo digital signal is beyond
amazing. It may not replace analog, but Trbo is an amazingly robust system; and the clarity
of it's digital signal makes P25 sound like a tin can and string (ok, that may be a bit of an
exaggeration,but in constant testing, Trbo's signal is better and has more clarity than P25).
The Trbo system flies it's flag under the auspices of KC2CQR
I also don't agree with e911god when he says "more Trbo Garbage". It may not be for mission critical comms such as P25, but calling Trbo garbage is irresponsible. Trbo is indeed limited to the Big M, but Vertex, HYT, and Tait are also planning DMR compatible radios. Trbo was never intentioned for public service. It was originally aimed at professional business users.
Wow. A whole Hamsexy repeater.
Honestly, I think using protocols that are "aimed at the professional business user" by hams who either work for commercial shops or have deep pockets is just a kind of snobbery. Regular ham radio isn't good enough for the elitist ham.
All these guys really want to do is to "play radio." Their jobs and the authorized uses for the fancy gear don't allow this, so they create high-dollar ham radio as a sort of gated community playground.
Actuality it will be the K2QQJ/KC2CQR mototrbo repeater system . 449.7250 ....73's kc2cqr ....Frank Dinaro trustee. It took a lot of people to make this happen . I would like to thank everyone for the hard work they put in to it ...73'sThe Trbo system flies it's flag under the auspices of ..."K2QQJ

449.7250 K2QQJ "MetroCor Coordinated"
The role of coordination is a "balancing act", where the interests of all spectrum users are taken into account. The ongoing needs of the Amateur Radio community have caused this role to evolve from simple FM repeater, link and control channel coordination into one of more efficient spectrum management. Spectrum management must now account for the needs of weak signal, FM simplex, ATV, packet and other new technology spectrum users.
