This is the way I do it on both GMRS and ham. I give it in plain old alphabet first and if the other party doesn't understand then I give it again with the NATO phonetic alphabet.
However, when someone uses the NATO exclusively, it doesn't bother me a bit.
@RogerSpendlove I found replacement clips for the GM-15 Pro but they didn't come with screws. Went back and forth with the seller about the screws. It sounded like they didn't understand me. Of course that could have been intentional.
That is just sad. I guess that is where Randy came up with the term "sad ham." I have been very fortunate that I have not had such experiences. All the hams I associate with are very good people. And many of them are dual licensed.
That 778 is the one I have. Nice radio for the price. It can transmit on 2m, 70cm, and GMRS if you pick the right band range.
Yes, I know, I'm slapping my own hand for saying it.
@UncleYoda That is my understanding as well. A GMRS "type certified" radio is not supposed to be able to transmit outside of the GMRS frequencies in any form or fashion.
