Earlier in this thread, a man stated that he would be admonished for suggesting that a pop oldies station should be tried instead of an urban station. Happens all the time on this board, won't work, no money in oldies, so on and so on. But then he was called blatantly racist for even suggesting such a thing and was called coded. I highly doubt that comment had anything to do with PPM. I'm a Southern white man with mixed race children and grandchildren and I've been dealing with racism my entire life. To see the word racist just tossed around like that is insulting. Racists are truly evil, disgusting people. Trust me, I've met enough of them. So, I'd like an explanation of what was meant by coded and why it got a seemingly innocuous statement labeled as racist.Very abbreviated answer: in the 50-ish or so largest markets, Nielsen uses "portable people meters" (PPMs, little pager-like devices) that are given to ratings panelists instead of the older diaries they used to get (and still get in smaller markets).
The PPMs are constantly listening to ambient audio as they're being carried by ratings panelists. Stations that "encode" have a device in their audio chain that inserts a coded series of pulses into their audio. In theory, the pulses are supposed to be masked by the station's own audio in a way that human listeners don't hear the encoding, but the PPM devices can hear and log them. In practice, there are a variety of reasons why the encoding can be audible - or more often, that the devices designed to enhance the audio for better encoding are actually distorting the audio in a way that can be grating to the human ear.
