Just saw a video by one of our members (I'm talking about you, the Queen of all that is GMRS) and it reminded me to complete the attached document. It's something I started a few months ago and it covers the definition of a channel or Channel. It's absolutely where the problems lie in understanding more complex radios. I know it did for me initially, but hey, I'm a smart guy right!? OK, maybe it took me a lot of reading but I got there.
As this is the internet, I will add that this is pretty much a first pass. I am not married to this, so if I got something wrong, or anyone can clarify something, please, please let me know. This is a community that wants to help others, which is what I am attempting here.
I got a little more in depth than originally planned, but held back from going all engineering nerd on this. I wanted to keep this beginner friendly. So if you are a novice, read this and let me know if it made any sense.
