Chicago2008 2 Posted January 27 Share Posted January 27 Good afternoon, was on radio reference and found this https://www.radioreference.com/db/aid/2820 can someone explain how some of these frequencies work? Finally the WMAQ channel of 450.55mhz is labeled as sky 5 IFB, however you can here studio audio on it. Thanks Link to comment Share on other sites More sharing options...
compubit 670 Posted January 27 Share Posted January 27 I worked in Radio/TV Engineering back in college (30+ years ago), and suspect that WMAQ broadcasts studio audio over that frequency. It’s probably intended for their helicopter (thus the name “Sky 5”) and isn’t subject to cellular signal issues up in the air (signal strength, tower switching. Etc.). I suspect it’s probably a narrow-band signal that gives the remote end the ability to hear live from the studio - and is probably a simple analog signal, so it shouldn’t have the “lag” you often see from remote shots using cellular service (even if just for the IFB).
