Re: Hum on WPTF
Chris,
I invite you to stop by Highwoods one of these days to take at some of the changes since you left. Give me a call and I’ll be happy to show you around. There’s still room for improvement, but we have a completely upgraded network infrastructure with high quality managed switches, VLANS, home-run network cables throughout the building and a network device (FatPipe) that aggregates the bandwidth of three ISPs. Processing for WQDR and WBBB was upgraded to 8400 Optimods a couple of years ago. That was the PD’s choice—they could have had Omnias if they wanted. PTF is using an Omnia AM 4.5. New digital audio hardware and software for WPTF, WQDR, WBBB, WWMY and WYMY was installed two years ago. WQDR’s control room has been upgraded with a new console and completely rewired—by engineers who know how to do it right. Email me and I’ll send you some pics. In the four years since I’ve been here, new transmitters have gone in for a station or two every year. This coming week we’ll be installing a new STAC12 phone hybrid for WPTF, receiving a new 500-foot tower in Goldsboro and setting up an ISDN box in Allan Handleman’s home studio in Charlotte, among many other things. It’s STILL of lot to keep up with—16 radio stations, a traffic network, a farm network and a new Internet-based project, “State Government Radio.” Yes, the Limbaugh hum is on a punch list and I’m embarrassed it’s dragged on so long. But the equipment to fix it is in house and is scheduled to be installed in the next day or so. The point is CMG IS a good place to be these days—for people in all departments including engineering. Our day to day operations are led by one of best radio managers in the country, Phil Zachary. QDR is the top rated and top billing station in the market. The Raleigh cluster is the top billing cluster in the Triangle. We are locally owned and do not answer to Wall Street. Any “Po Broke Engineers” who are interested in joining the team should contact me directly.
