I'm not sure why you brought up cross-band repeat when the OP is just wrapping his head around the concept of repeaters, BUT I just set up the feature on my mobile Yaesu FT-8800 and it is indeed very sweet.As ScottASchultz said, most will do the simple single band repeater operation.
One bell (or whistle) that I personally do not have (but, also a feature that I don't need right now) is cross band repeat. ...
When you took your test to be licensed, was it through a local ham radio club? If you have the contacts, call someone to assist you in how a handheld, or, mobile radio works. It is going to be a better learning tool than asking a question here in the forum. You won't get so many different and confusing answers. All ham radios that do 50Mhz and higher have an automatic repeater offset built into them. The radios are smart enough to know the difference on whether or not you are programming a simplex frequency, or, a repeater pair. This is where taking classes before getting licensed is important. Not only are you taught the basic electronics, but, operating proceedures, rules and regulations, and how to setup a radio and use it. At least it was when I taught classes.which ham radio is a good one? i want a radio that can do repeaters like some how program the rx and tx in the same channel?
or do i have to flip channels all the time
let me know...thank you for ur help in advanced
