I actually miss the Blues channel that was on WXRT-HD2. I guess the only HD2ís and HD3ís that are likely to survive are those driving FM translators. As for AM HD which was a boondoggle from the engineering bench all the way through Marketing, there are only 2 signals I can still detect: AM 920 WBAA West Lafayette, and AM 810 WGY Schenectady. I can never lock them, just detect them. I would not be surprised if they just forgot the devices were still on.
