So I am looking a versatile radio to be the “Does everything” radio with a lot of features that probably doesn’t exist so I will list them in tiers of requirement.
Must have FRS, GMRS, and MURS.
Rechargeable or rechargeable AA Battery compatible
Able to scan police/fire/other emergency frequencies (I doubt there is a two way that does this)
Hi, A multi service radio will be a tall order for several reasons.
First, you will probably not find such a radio designed for FRS, at least in the US, as FCC rules do not allow FRS radios to have removable antennas or operate above 500mw.
Second, while there are numerous dual band amateur radios on the market with a lot of high tech features that can technically be programmed to scan FRS, GMRS, MURS, municipal and emergency frequencies, none of them are Part 95 type accepted by the FCC to transmit on FRS, GMRS or MURS.
Of those radios, The Baofeng UV-5R is one of the least expensive and most popular.
In the US, if all you want to do is listen in, no one will bother you. However, I would highly advise you to purchase a scanner, as that will prevent you from accidentally transmitting on these frequencies.
