A couple of months back our radio station's production director received a knock on his door about 8PM one night. It was an FCC inspector. Now, of all the people at the station, I always assumed it would be me who got the knock -- after all, I'm the one with all the gadgetry.
He was going from house-to-house in that block looking for someone with equipment that was putting out a strong signal right on the frequency of Philadelphia International Airport's localizer. It turned out to be our production director's next door neighbor whose HDTV converter box was emitting a spur through the TV antenna. Ya gotta wonder how some of these things are built...... -----Original Message----- From: irca-boun...@hard-core-dx.com [mailto:irca-boun...@hard-core-dx.com] On Behalf Of sa...@sounddsl.com Sent: Friday, February 27, 2009 1:18 PM To: irca@hard-core-dx.com; ultraligh...@yahoogroups.com Subject: [IRCA] HDTV hash solved! (whew...) Hi all: Thanks to the many suggestions and ideas. I tried 'em all, and the one that worked was to minimize the length of coax between the little UHF circular antenna and the converter box. The converter box itself gives off a little RF but only up close, similar to most modern electronic gear. However, when you hook up an external antenna, the digital converter apparently radiates the noise over the antenna feed cable. I had an elaborate switching network for when I utilized more than one antenna, and bypassing all that got rid of the noise. Hope this helps someone else faced with this problem! "Hash" is a gentle descriptor - it was more like a solid high-pitch whine/buzz which precluded DX on the lower band. Fortunately, peaceful coexistence has been restored between my DXing and the girls' TV viewing (in fact, the signal on the TV is a little better!).
