WODS MOVING TO PRUDENTIAL

[dumber than a box of hair]

Incorrect. 35% of all radio listening is done in vehicles.

Citation, please.

(note: I think you are correct, but you should provide a link to a study or something that backs up a claim like that)

Repeated statistical analyses by Arbitron. The last one I saw said that AM drive is about 31% in-car, while PM drive is 37%. Percentages are significantly less outside of drive times.

How can WKLB-FM on 102.5 MHz Interfere with WUMB-FM on 91.9 MHz????????????????????????????????????

Read the "specs" page in the owner's guide for any FM broadcast receiver in much of the world and it will list the FM IF frequency as 10.7 MHz. Without going into technical details, two stations that are 10.6 or 10.8 MHz apart and have strong overlapping signals will do funky things to receivers wherever they tune within that strong signal area. That is, two stations 10.7 MHz apart (+/- 100 KHz) could prevent interferrence free reception of those and of any other stations on the dial.
By "stations", I include the audio and video carriers of analogue TV channel fives and sixes.

The worst example of the phoenomenon I ever heard in this area was back in the mid-'80s. A friend lived on the north side of Beacon Hill, facing the north shore. WFNX was then still transmitting from Lynn, and WBUR was then transmitting from the BU Law Building (now their auxiliary).

The reception from the north side of the hill brought in WFNX strong enough from the north shore to cause my friend's cheapo Technics receiver to IF modulate WFNX with WBUR, resulting in an audio image of both stations superimposed on top of one another across the entire FM dial on any frequency where there wasn't a local station strong enough to cut through it. There was no static or FM "white noise" anywhere on the dial, just WFNX and WBUR superimposed on any locally unoccupied frequency.

I typed without thinking.
Only 98.5's are affected by channel six audios.
The rest are all FM to FM.
