Don't worry, I've got the safety on. ;D
Quick report as of midday Thursday - on my Sangean HDT-1, on HD-1 I see two rows of PSD:
Row 1 = "WGBH-HD Boston 89.7 mHz."
Row 2 = "WGBH-FM 89.7 Bostons NPR Arts and Culture Station"
On the HD-2 I see no PSD at all. But as I've previously noticed, often the Sangean will show no PSD when other HD Radios will show something.
BTW, has a hard (or even soft) date been set for when the FM studio operations will start from Brighton Landing? Or have they already?
