The Uniden Grant XL is an excellect radio. The Grant XL has a built-in SWR meter, unless it has been bastardized to switch for a channel mod. If you find a Grant XL that is clean and hasn't been overly modified, go for it. The ones made in the Philippines or Malaysia are good. I just recently sold mine on EBay since I wanted to finance an Icom 718 for HF work. (I am a licensed General class amateur)
The "roger beeps" you hear on 2 meter and 70 cm repeaters are most likely the "courtesy tone" on the repeater, not roger beeps built into the radio.
Or someone has their "wires" access button turned on.
