A handful of AM stations reportedly have turned off their HD Radio signals out of concern for analog interference to neighbors on adjacent channels.
Of these cases, Ibiquity’s Bob Struble said, “Are we aware of it? Yes.” In many cases, when an Ibiquity team goes to a site to help with an IBOC install, a station may already have antenna problems, he said.
“We’re seeing arrays not pointed in the right direction and power levels that vary. This is to be expected,” he said, as Ibiquity helps stations work through AM digital implementation issues.
Ibiquity Vice President of Marketing Dave Salemi said some of these stations are short-spaced. “We’re finding manufacturers step in and resolve problems,” he said.
