McLarnon's site last had a whopping 82 out of 4700 operating AMs with HD on 24-7, virtually unchanged from 15 months ago.
Yeah, and of those few AM stations that broadcast HD you get a fluctuating figure as to who is doing it 24/7 or just daytime. Sometimes you hear reports of AM stations that have HD on during the day, then it's off, then it's on again. What a mess!
Last year, if you'll recall, Citadel had decided to stop broadcasting HD at night on ten of their 16 stations (of the 66 AMs Citadel owns) that have HD Radio installed.
According to an internal memo, the reason was, "In response to the lackluster performance, the limited benefit, and various reports of significant interference”.
Citadel Director of Corporate Engineering Martin Stabbert said that they were "stepping back to evaluate performance".
After a year of 'stepping back and evaluating' I wonder what conclusion they've come to?
