I'll start the debate......I believe I have heard/read that channel 20 was the GMRS national call and or travel channel, but have heard and seen many people mobile using channel 19 as there travel channel, can we settle that debate, maybe with this site most likely being the best known site for gmrs info we can get everybody on the same page so a channel is established, either way, I would like to start calling out on some channel rather than listening in hopes of spurring some activity in the many quiet radios out there thinking this will NEVER take off. Thoughts?
