Speaking of 740 kHz AM, does anyone in the Boston area remember WCAS, Cambridge? A little 250-watt daytimer, but they rocked. They took a lot of listeners away from the big ones like WBCN during their limited broadcast hours.
I used to work with Bob Bittner back in the WNTN days (I was chief engineer for a while after fixing the transmitter that no one else could fix).
Bob funds the station using DONATIONS (and some infomercials that run on the weekends), and it must be working - he's been running the thing for a while now.
The music is very good, but not QUITE as good as "Zoomer Radio" from Canada. Bob plays some '70s drivel from time to time (what IS this infatuation with '70s music that most radio stations have?).
I live about 40 miles from the antenna site, and they are VERY weak here during the day on a car radio, but quite listenable using a bigger antenna such as a 160 meter dipole.
