Station owners Gillian and David Sutton are asking the community to support KRSN AM 1490 by attending Thursday’s Parks and Recreation Board meeting.
This is the couple’s first meeting, set for 5:30 p.m. at the Aquatics Center, to gain county approval for placing a broadcasting antenna on North Mesa in the corner above the roundabout.
“We are asking everyone to come out and support their local community radio station and its desire to serve them better,” Gillian said.
AM radio waves are ground waves affected by gravity, she said, and work best when the antenna is near the elevation of the area to be served and not at a lower elevation.
David explained that an AM radio station needs a grounding field equal to about a 1/4 wavelength of its frequency. KRSN’s frequency is 1490, meaning the station requires a grounding field radius of 186 feet.
“This equates to a plot of land more than two acres in size,” he said. “We have measured all the parcels of vacant land in the Los Alamos townsite and have found that this parcel will work best as well as meet all federal requirements.”
