Tonight I had my first GMRS radio contact in Baltimore, Maryland. We chatted for about 10 minutes. Ham radio operators would call it a QSO. The gentleman with whom I spoke is newly retired and comes from using CB radio.
This reminds me that 2 way radio communications is a social medium. You put out your transmission and many people can hear it, just like a tweet or post. The difference is that radio can be more ephemeral.
