We received several calls this week regarding MURS radios. We felt the questions and answers might be of interest to others considering the purchase of the radios offered at www.mursradios.com. The first question was from a church wanting to know if the MURS radio could cover a 100,000 square foot, three floor facility. The answer is that a 2 watt VHF MURS radio can be expected to cover up to 15 floors or 250,000 square feet.
A contractor called wanting to know what kind of range could be expected for outdoor use of MURS portables. The answer is that a VHF 2 watt MURS radio has a Line-of-Sight range of up to 2-4 miles. Range can be extended with our MURS fixed stations when required.
Our answers are based on engineering probabilities based on established testing and performance, not marketing mumbo jumbo. Obviously, there can be exceptions, but these answers should help prospective users to separate fact from fiction.
Another common question is why can't any FCC type approved 2 watt radio be used for MURS operation? There are two answers involving both legal and technical issues. Legally, any radio operated on MURS frequencies must be approved under FCC Rule Part 95, Subpart J. Radios approved for FCC Rule Part 90 have different technical standards such as channel spacing. MURS radios have a channel spacing of 11.25 kHz versus 12.5 kHz for Part 90 radios. Long story short, if the radio is not Part 95 approved, MURS channels cannot be used.

Another frequent question is how many channels are available? The answer is five, although the basic five frequencies can be configured for different functions such as selective call paging, receipt of alarms or device notifications, private talk groups, etc. We offer two MURS portables. One has up to eight channel configurations, the other up to ten. If you have additional questions about MURS, please visit our web site at www.mursradios.com or just give us a call at 205.854.2611. We'll be looking forward to hearing from you!
