Frank,
We have a set of Motorola Talkabout 2-way Radios that 'advertise' a range of up to 18 miles & have several features, including NOAA Weather alerts & an Emergency Alert Feature** (see note below). We've had them for about 4 yrs, and been extremely pleased.
We use them when DH goes off fishing & I stay at the campsite; or when we hike (in case we ever get separated)... many times there's no cell phone service where we camp. We also use them when traveling (caravan) with other RV friends... shhh, don't tell, but one couple is directionally challenged and tends to fall behind & get lost easily.
Different cell phone providers & occasionally no service, sooo we keep in touch by radio instead! Even with the radios in 2 different moving vehicles & 2-3 miles apart, we've had no problems.
The model # we have (T8530R) is no longer listed, of course, but the
Talkabout MR350R has the same features, and 'advertise' range of up to 35 miles.

**NOTE: The emergency alert feature: "When the alert button is activated, the radio transmits an alert siren followed by transmission of spoken or incidental sounds. This allows you to send the signal to other radios and warn of impending danger." [quote, in part, from website]
Hope this helps.
