Okay. Thanks. What about just MURS radios without FRS. Does anybody sell these?
Probably the best legal MURS radio on the market is the Ritron PT-150M. My brother in law is using those for his tower crews. He's been running them for a couple of years without issue.
The PT Series handheld 2-Way Radio is an analog, narrowband radio. Lightweight, tough and reliable - well suited for commercial and industrial applications.
Programming software is free.
These are probably out of the budget range for most hobby level users, but they've found a market in construction.
Is it true what they say about the mileage range for GMRS in the web advertisements? Can these miles be achieved without a repeater?
Technically they are not lying.
Usually the advertisements will say something like "Up to 30 mile range". And it's true. If you and a buddy were each on top of a high hill or mountain 30 miles apart with an uninterrupted line of sight between both of you, it's very likely you'd get 30 miles range. Remember, amateur radio operators can talk to satellites with 1/2 a watt.
But in any sort of real world application, you are not going to see 30 miles. What you'll get is the "Up to" part. 500 feet falls inside the "Up to
30 mile range" claim. A few watts on UHF with inefficient antennas and poor receivers is probably going to get you 1/4 to 1/2 a mile at best. In some cases you can do better, but you'd really not want to rely on that as a common occurrence.
