I'm sure you already know this, but if reasonably priced, a nice sounding audio stream is the way to go considering AM reception at home is challenging for the average listener and nearly everyone has home internet. Many cars would benefit too as bluetooth stereo is becoming standard equipment and data allowances are going up on most mobile phone service providers.
Oh yeah, Primquist (sp?) in NJ has streaming for $40 a month with unlimited listeners....Also the Cafe on the 1st floor of EP is switching from TWC's top 40 music format to the station...and I think I have the bldg mgr switching all the floors too....(probably do some trade).
