Yes, I only heard three. They were:
457.525 CC3
457.550 CC5
457.575 CC7
It was plain DMR, not Capacity Plus or Connect Plus. I did not get any Talkgroup numbers or figure out TS1 or TS2 usage. Of the three, 457.575 seemed to have the most usage when I listened. I wonder if this is well planned so that other Carnival ships, using the same frequencies, have different Color Codes, in case they are in the same port at the same time?
But, back to FRS/GMRS, very little usage, as I posted earlier, particularly compared to cruises I was on in the past. The same with European PMR channels. Actually, a little bit of FRS/GMRS and NO European PMR. I saw very few FRS/GMRS, too. I still remember that beep from other cruises, though. I do not miss that in the least.
Of course, had I brought my DTR550s, somebody would have said that about the DTR noise!
