It was a joke. There was a guy on here a year or 3 ago that was going to reinvent CB on 38MHz FM/digital since "no one" was using it. We pointed out federal/military allocations, as well as other shortcomings.
Listen before you talk has always bean about a 50% FARCE! if I'm 75 mils away from a repeater that's on a high mountain. And you are on the other side of that mountain talking on direct or even a lower level repeater. I'm never going to hear you! And type acceptance has never required repeaters to monitor inputs for users on a different tone. That's just a fact. And to go one further the FCC can't require it on part 90 either because they allow digital and analog to talk on same freqs and the digital radios don't monitor analog at all, most are programmed by the shop to give priority to customers that pay for service. Motorola DMR RAS systems don't monitor anything that don't use a ras key. And the same can be said for Hytera systems. The person at the FCC that makes GMRS and part 90 rules don't really know much about how radio actually works they are mostly all just ATTORNEYS not RF ENGINEERES. If the FCC is going to allow GPS and texting on GMRS they may as well just allow multi mode on GMRS analog or digital! No matter how you look at it IF they transmit GPS or txt over GMRS its JAMMING! Kinda like those fricken call buttons on the bubble pack radios that the FCC said should not of bean approved on GMRS!!! Cause the FCC type acceptance department NEVER looked at the rules before approving the stuff that the GMRS/FRS radios did they were under pressure from radio manufacturers to just approve them. Big money talks Motorola , Uniden and others the FCC don't say no!
robertmac didn't seem to like the Fact I mentioned Frs is licensed by rule either.
As a ham of 43 years, an active on 70cm still, I wouldn't mind if 20 or so 6.25.khz DMR channels were allocated for a PMR-like band somewhere in the 420-426 mhz range. It used to be used for ATV but that's virtually non-existent anymore. And hams who want to do ATV that can just move to 1.2ghz. Hams have always used 70cm on a secondary basis anyway. But I doubt it would be necessary.
Have you ever PAID for coordination on part 90? There is NO real coordination!!!! they will charge you for it but they will rubber stamp it as being done and the FCC has no staff on hand to verify its bean done correctly that's a fact. We have paid for it and its NEVER RIGHT! Plus the FCC never gave guard band at either end of the GMRS spectrum, GMRS was 25kc now its like 20kc but most still run 25. The FCC coordinators put commercial users within 6.25kc of 462.550 and 462.725. Today in Yuma Az there is someone running DMR on 462.55625 CC11 TG 1012 Slot 2 Radio ID's 1 , 2021 , 2023 so far. Looks not to be Fisher comm. no cw id or voice id either. As I stated in other posts. The FCC coordinators put all kinds of users in the wrong spectrum just so they can collect the fee!!!! Coordinators just don't care as long as they can BILL for it. Cause no one at the FCC checks! If its properly formatted they rubber stamp it. Kind of like the county recorders. Someone steels your property because there is no one verifying the paper work just that its properly formatted! I think that's why the supreme court said a while that the GOV can't write rules, enforce them and then pros acute their own stuff! That's actually what the FCC has done from the beginning! They are a self appointed agency they are not listed in the constitution. Don't hate me its all facts if you do the leg work.
I have a bunch of coordinated frequencies, and they absolutely did their job. There's nobody anywhere close to me using the frequencies, and this is in Los Angeles County. Another frequency I was specifically looking to get belonged to another coordinator, and they went through them to get it approved for my use.
It's a cap+ 2 site 4ch system with enc talkgrous TG201,202 and 203 throwing CC14. 467.60625 is showing as the "rest ch" ch-3.
Peter, wondering if it comes and goes, not a band opening, but thinking one of the West Coast Cruise Ships....??
Railroads. The Federally-mandated Positive Train Control system, which is required on any line that carries hazmat or passengers (except isolated tourist lines), uses 220-222 MHz for data between lineside equipment and locomotives or control cars.

I don't know if you are old enough to remember the "Class E CB" proposal from the early 1970's. There is pretty close to zero on the web about it, but there was a proposal to take part of the (still mostly) unused 220 MHz band and carve out a VHF FM (narrowband protocol of that day) with 25 Watt power limit and a lot more channels than the 23 that Class D CB had at the time. The one internet reference I found to Class E a few years ago said the proposed number of channels was 40. I seem to remember something bigger; like 60, 80, or maybe more. I still think it would have been a great thing for all, but the greedy hams and the ARRL soiled their diapers and cried until the FCC killed the proposal. A decade or few later, the FCC sold a big chunk of that (still) under-utilized 220 band to UPS, who I understand never really used it. 220 would have been great for base, mobile, ht. Ht's would have worked great from inside an automobile.
Probably because it maybe would cost the amateur band loss of spectrum.
