The Multi-Use Radio Service (MURS) uses channels in the 151 – 154 MHz spectrum range. The most common use of MURS channels is for short-distance, two-way communications using small, portable hand-held radios that function similar to walkie-talkies.
Similar services include General Mobile Radio Service (GMRS) and Family Radio Service (FRS).
MURS is authorized five channels that were previously in the industrial/business radio service and were known as the “color dot” frequencies in Part 90 of the FCC rules.
