Title: KBDL --- Yay
Post by: Gecko1 on March 20, 2008, 12:44:22 PM

It's nice to see KBDL back up again, especially when it comes up just before my overnight stay there.  8-)  (Wonderful hotel on top of the terminal with windows overlooking the runways. I went there last year with my scanner. Very cool.)

Anyway, yesterday there was a constant low frequency hum, about 60-80 Hz. (AC interference in audio cable??). Just thought I'd let you know, and say thanks for the feed.

BTW, it's down now (201641Z). Is that concerning the above problem, or just a routine thing.

The feed is hosted by the New England Air Museum (NEAM) and the 60 Hz ground hum is a known issue that will be worked out shortly.

Ah.... That is virtually next to the tower. No wonder there is such a strong signal. Good luck to them with the hum.

Okay, BDL's up again, and the hum is not noticeable on my speakers, but it is obvious on headphones. I measure 121 Hz and its integer harmonics. (Not the 60 Hz hum this time?) Not a serious problem, but since I don't hear it on JFK, I thought I'd report it anyway. Any data helps.

Regards.

Thanks...we'll be working to eliminate the hum there in the next few weeks or so.
