Good afternoon everyone. I am new to radios and just got my GMRS license a couple of weeks ago. I purchased a Baofeng AR-5RM. I plan on checking out some other radios before figuring out which ones I like best. I have been able to program it with CHIRP and connect it to a repeater close by. It is my understanding that when I transmit on the repeater frequency, the repeater picks up my broadcast and then retransmits it to extend the range of my radio. I have noticed that I can transmit from 8-10 miles away from the repeater and it can pick up and retransmit my transmission with no issues. However, if I am on a regular simplex channel (21 for example) my range is nowhere close to that for a radio-to-radio transmission. When using radio to radio channel 21 if I am more than a mile apart they don't seem to connect. Can someone help me understand how I can broadcast to a repeater 8-10 miles away but not to another radio a little under 1 mile away? Thank you
