Radio-Board-Op: "Highway Radio" has been around for 40 years now. The VP of Marketing for the long-gone Desert Inn (it's where Wynn is now) realized that, in the 70s, there were few, if any, listenable signals for most of the last two hours of the drive into Las Vegas from L.A. The stations (it took two FMs, at 98.3 and 99.5, with sticks on Calico Peaks near Yermo and Clark Mountain near Mountain Pass to cover that area) went on the air in February of 1980, with a morning show targeting Barstow listeners and advertisers and programming the rest of the day featuring artists that played Las Vegas at the time and advertising from the Vegas casinos. Eventually the music morphed to a straighforward Adult Contemporary format.
In the time since, a third FM signal has been added, one of them has now been re-oriented purely to serve a Barstow audience, and the stations have been sold dirt-cheap ($620,000) to Heftel after the original owner went into bankruptcy.
I lived in Vegas from '84 to '86 and drove to L.A. a few times. The stations were actually pretty mediocre at the time. It'll be interesting to hear from you what they sound like now.
