Last summer, I wrote about how nearby 820 WWFD in Frederick, MD, ended its analog transmissions and went all-IBOC, the first traditional FM or AM station in the United States to do that. WWFD, at 53 miles away from my Northern Virginia home, was an occasional visitor during the day prior to its HD transition, but it did not fully decode until January 14. That decode lasted a few seconds, just long enough for me to get the picture below from my Sangean HDR-14. This screenshot has been added to my AM HD Radio Screenshots page.
