latest receptions - 2009 archive

During my occasional band scans, I tune in to each audible signal I can find and make a cursory attempt to identify it. Schedule information from EiBi and Primetime Shortwave aids in station identification. I collect and publish these logs so others can see what's possible to receive with a portable shortwave receiver in northern California. This list of receptions doesn't include items from my reception reports which I publish separately.

Here's my list of shortwave band scan receptions during 2009:

analog tv channel 6 used for radio

While reading about VHF on Wikipedia, I learned about a company called Pulse 87. This company broadcasts low-power analog television on channel 6, with the audio subcarrier appearing at 87.7 MHz. Low-power television is exempt from the digital tv switchover, so this analog broadcast works as a radio station at 87.7 MHz. This unusual radio station has a "hot dance airplay" format.

Pulse 87 currently operates WNYZ in New York City, while plans to operate stations in other cities (Washington D.C., Los Angeles, and Chicago) have run into various problems preventing their launch.

Wikipedia also suggests that digital television in the channel 6 frequency (83.25-87.75 MHz) has had problems with interference, so it's possible that the FCC might release that part of the spectrum for radio broadcasting.

Digital radios intended for the North America market are often confined to the 88.1-107.9 MHz range, so as a rule, this station's target audience is limited to those who have radios without that limit (such as imported radios with a wider range for FM, or analog-tuned radios that have less precise FM broadcast band boundaries.

radio factory quality control

Sometimes, I wonder what it's like to work in quality control at a shortwave radio factory in China. I imagine the conversation with a new employee could go something like this:

Employee 1: "When I tune through the shortwave bands, all I can hear is loud orchestral music."
Employee 2: "That means it's working."
Employee 1: "But where does it come from? And why is it the same on so many frequencies?"
Employee 2: "Just put the QC PASS sticker on the radio, and wrap the package!"
