Lets face it... DIgital is the future. It's just a matter of time before GMRS will be allowed to go digital. FCC has been hammering home the idea and need for better use of the spectrum for years and now it's time they listen to their own suggestions and approve digital for use on the GMRS band. There are many places in my travels over the years that have been and are using digital on GMRS. Is it leagal???? Not currently, Is it making better use of the spectrum???? Yes...
Also, let us not forget, the digital you are hearing and questioning may be by someone that applied for and got a waiver to do testing of digital on the GMRS frequencies..... and I couldn't think of a better place in the country to do those test especially with as much congestion of frequencies there are in that area. I know over the past years that getting a waiver is not that hard. I've even asked for a few myself, and not that long ago.
GMRS radio operators are entitled to the same new technologies as the commercial, PS, and yes even Amateur's radio operators are allowed. Lets not complain, but support the use of it, for testing or otherwise, as we all know that sooner or later, either by force or appreciation for the desire to have better use of the spectrum, FCC will eventually approve digital for GMRS. People should be doing what they can to learn all they can about digital communications so that when it comes about and approved next year they will be ready to move forward with upgrading to digital.
