After what seemed to be several years without using HD Radio, local 104.1 WPRS Waldorf, MD, 23 miles away @ 50 kw, has resumed the service. Because of this, 103.9 and 104.3 are now unusable for DXing. Prior to the turn-on of IBOC, 103.9 WOCQ Berlin, MD @ 107 mi and 104.3 WZFT Baltimore, MD @ 57 miles away were common catches on WPRS’ sidebands. However, since WPRS puts in a very strong 50kw signal into my Northern Virginia home, I could often hear bleedthrough on 103.9 FM from the 104.1 FM analog signal.
This isn’t the first time WPRS had an ‘on-again, off-again’ relationship with HD Radio. According to my log records, the station, which was airing IBOC in 2008 when I obtained the Sony XDR-F1HD radio, dropped the service in 9/09. I don’t have any notes of the station resuming IBOC since then.
