Activist SD also owns KUMI, a 100 watt NCE located in (no joke) Glamis, CA. It's a gas station and convenience store surrounded by miles and miles of sand dunes. Pop count is ZERO.
The population of Glamis reaches its peak during the Thanksgiving and New Year's holidays when hundreds of jeeps, dune buggies, and two- and three-wheel motorcycles populate those sand dunes for miles around. My late father was big into that and between 1970 and 1977 (with the exception of 1971), we were always at Glamis for the Thanksgiving Day celebrations. And, of course, the sand got into everything, including the valuable portable radios I took along on those trips.
We usually camped in the dunes about five miles east of the store and gas station off of California State Route 78. For all of the trips I made there, there were only five Stateside AM radio stations that could be received easily:
560--KBLU, Yuma
, AZ1230--KXO El Centro, CA
1300--KROP Brawley, CA
1430--KAMP, El Centro, CA
1490--KCIO, Calexico, CA
Of these, only KROP and some of the Mexicali stations put in good local signals at night. FM was interesting as where our camping spot was located (we chose the same spot every year), you could, with a decent whip antenna, pick up many of theLos Angeles stations on Mt. Wilson and some of the San Diego stations as well. It was great after the 1972 move to Phoenix as it allowed me to hear some of KRTH's oldies programming from the campsite.
