If and when Sirius and XM Satellite Radio get the green light to merge, new radios will have to be manufactured to allow both services which use different technology to be heard on one receiver. The FCC had always mandated that when satellite radio was created, both satellite networks had to be heard on all receivers. Somewhere along the way, the FCC let this little detail slip away. Could you imagine an AM/FM radio that only receives one station? Well, actually, I can because WBEB-FM, Philadelphia founder Jerry Lee used to manufacture and give them away to advertisers before a crackdown stopped his great promotion.
