New Technologies and Design Concepts in Radio Automation (Not Your Dad’s Automation System)
Presented by Don Backus, Broadcast Electronics

Don Backus
Don Backus

Many current radio automation systems trace their roots back to the mid and early 1990’s and have maintained features, implementations, and designs that date back 15, 20, or even 25 years ago. As radio’s needs have changed over that time, so has the technology available to radio automation manufacturers. This session will look at modern automation technologies and how they can benefit radio broadcasters of all market sizes. From AoIP to powerful database structures to flexible operation and redundancy configurations to simple yet powerful user interfaces, today’s (and tomorrow’s) radio automation technologies offer much to streamline workflows, save and generate revenue and improve on air sound while improving the ability to be as ‘live and local’ as possible.

10:30 – 11:00am
Evolution of Solid State FM Transmitters
Presented by Don Backus, Broadcast Electronics

It wasn’t too long ago that solid state FM transmitters became widely available, eliminating the need for costly tubes, but at a higher initial cost. As time as gone by, several generations of solid state transmitters have produced higher efficiencies and decreased costs, but generally at lower power levels. Now there are several higher power solid state options in much more compact form factors with new technologies designed to improve efficiency, reliability and serviceability in the field. This session will look at some of the new tech in FM transmitters and discuss the benefits to radio stations.

Engineering Spotlight: Michael Kernen, Greater Media (Detroit)

We’re pleased to begin a new spotlight series featuring the hardworking engineers at our stations.  To nominate an engineer for a spotlight, please email Alisha Clack at clack@michmab.com.

MichaelKernen_400Michael Kernen
Michael Kernen is Chief Engineer for Greater Media in Detroit and oversees radio stations WCSX-FM, WRIF-FM, and WMGC-FM.  He started at WRIF 28 years ago, the last 23 under Greater Media’s ownership after they acquired the station.

Brief Engineering Resume:
Michael:  My love for music lead to an interest in radio. My uncle is Dick Kernen (V.P. Specs Howard School of Media Arts) and I would frequently get up a 5am on Sunday mornings to go with him to help with his Sunday morning live radio talk show. My cousin Bob Kernen (V.P. and C.O.O. at Jacobs Media) and I would screen the phone calls and a few times I even ran the board. Radio hooked me and with my uncle’s connections I got an old Gates console from a WXYZ-AM junk trailer and Bob and I used it to build an “FM control room” in my parent’s basement when we were 14.

I took all 6 semesters of electronics at Dearborn High School, as well as every media class and computer class offered and uncle Dick convinced me to attend the then Specs Howard School of Broadcast Arts where I took everything they offered at the time – TV/Radio & Broadcast Electronics. I worked as an electrician during that time.

My first real broadcasting job was at WHYT and WJR doing whatever they’d let me do –programming board-op, promotions assistant, engineering assistant, running ballgames, and running Paul Harvey. I took a full-time job at Ron Rose Productions for about a year and then moved to WRIF where I’ve been since 1988.

Q: How did you get started in broadcast engineering?
Michael:  The part-time job at WHYT and WJR as an engineering assistant.

Tell us something about yourself that very few people know…
Michael:  I have a titanium plate in my head!

What is the best advice you’ve ever received?
Michael:  From my uncle Dick “quit driving around in a van with ladders on the roof! Call Hal Buttermore!” (Then CE of WHYT)

MSU Student Radio WDBM-FM (The Impact) Gets New Antenna

Michigan State University’s student-run radio station WDBM-FM (88.9 The Impact) replaced their 30-year-old broadcast antenna last week at the tower site in East Lansing.

Ed Glazer, General Manager of the station, said the old antenna outlasted its 15-year lifespan, but in recent years had been suffering from “diminished efficiency.”

The new antenna, which cost between $10,000 and $15,000 was paid for by the station’s general fund.  Workers from JT Tower Service, Clarksville, Michigan spend several hours in mid-Michigan’s chilly spring air working high on the station’s 300-foot tower removing and replacing the old antenna.  WDBM’s antenna is mounted on one tower of the WKAR-AM directional array.

More than 100 student volunteers work at the station, which has a music format consisting of alternative, rock and independent music as well as specialty music programs.  The station has been broadcasting since 1989.

 

Engineering: Barix Box Advisory

On April 6, The Alabama Broadcasters Association shared this with us…from one of their members:

“Someone is attacking Barix Boxes. Within the past 24 hours, several radio stations and at least one radio network have been compromised. The Barix receiver is pointed to an obscene podcast and its password changed so it can only be reset manually. This appears to have been in the planning stages for some time by the person doing it – apparently they have been accumulating passwords for some time. MAKE SURE that your password is of sufficient strength! Barix Boxes will take up to 24 characters…. In at least two cases six character passwords were cracked.”

Updated 9:16am on 4/7/16:  Apparently the reported Colorado signal hack was related to this Barix story.  Read about the KIFT signal hack here.

The stream programmer who had their explicit content aired on the Colorado radio station did their own investigation into the incident and provides some insight here.

Updated 2:10pm on 4/6/16:  Jason Walther, CE of Townsquare Media (Lansing) adds: “Best advice is to change your password to the web interface, and hide it behind a firewall that only exposes the ports needed to receive the stream (aka: port forwarding)

When these boxes are connected to a plain static IP and no changes are made, they are an easy target.

Also, if you have a Comrex Access unit that sits open with “Accept Incoming Calls”, you will get hacked the same. It is easy to disable incoming SIP connections.

Engineering Spotlight: Dave Grant, Cumulus Media (Grand Rapids)

We’re pleased to begin a new spotlight series featuring the hardworking engineers at our stations.  To nominate an engineer for a spotlight, please email Alisha Clack at clack@michmab.com.

Dave GrantDave Grant
CPBE, Chief Engineer, Cumulus Media, Grand Rapids.  Approaching 4 years, but this is his second time working for WLAV; was the CE for WLAV-AM/FN from 1986 to 1993.

Brief Engineering Resume:
Dave: My first radio job was screening calls for a sports talk show on WKBZ-AM (Muskegon). From there I started running Tiger games and eventually got a job as an on-air announcer at WLRQ-AM in Whitehall. (side note, WLRQ, currently WKLQ, is now owned by the Cumulus Muskegon cluster!) From there, I went next door to the FM station owned by Regional Broadcasting at the time. It was automated, so that left time to tinker with equipment. I became more interested in engineering, and started helping the regional engineer whenever anything needed repair.

I have been really fortunate to have had a couple of great engineering mentors over the years, and opportunities to work with them on a contract basis for a lot of different stations early in my career. This gave me a very broad education on repairing and troubleshooting a myriad of different types and brands of equipment. After that, I went to my first real full-time engineering job in Florida, and spent two years at two different stations before returning to be the Chief Engineer for Liggett Broadcasting. After that, I went to WLAV and spent seven years before the station was sold. I then decided a change would do me good and went into telecom working for a small local competitive telephone company. They were bought and sold many times before eventually becoming part of Verizon. All the while I kept a couple contract stations, I just couldn’t get radio out of my system.

I spent fifteen years in telecom, with the last two years working in Baghdad under contract with the U.S. government. After that ended, I began looking for full-time work again and eventually landed at Cumulus.

Q: How did you get started in broadcast engineering?
Dave:  I love music and grew up listening to the Big 89, WLS. Around age 13, my family moved to Muskegon and we lived near the WTRU-AM studios and transmitter site. I rarely could tune in WLS at home, so WTRU became my station. I listened to that station a lot, and originally was more interested in being an announcer. Eventually I would be an announcer for WTRU, but as it turns out, I didn’t much care for it. Engineering had already taken hold.

Tell us something about yourself that very few people know…
Dave:  My on-air moniker was Dave Lee.

What is the best advice you’ve ever received?
Dave:  Always treat people well, you never know when you might end up working for them. Karma is everywhere.

Engineering Spotlight: Keith Bosworth, Cumulus Media (Detroit)

We continue our spotlight series featuring the hardworking engineers at our stations.

Keith Bosworth
Chief Engineer for Cumulus Media (WJR-AM, WDRQ-FM, WDVD-FM) in Detroit.

Brief Engineering Resume:

2003 Specs Howard School of Broadcast Arts
2004-2013 Cumulus Media, Toledo
2013-Present Cumulus Media, Detroit

Keith shares his broadcast history:

“I started working as a Board op for Cumulus Media Toledo at WTWR (Monroe, MI) in 2004. Every time the Engineer (Kevin Hawley) would come in, I would watch him and I was a little savvy.  A few months later I was asked by Kevin if I would like to lend a hand installing new transmitters that were coming in for Cumulus Toledo. Halfway through the installs, he asked if I would like to be an assistant engineer, because as he put it, I was a good learner. Although to this day I tell him he was a good teacher.

After being at the Job for a few years and soaking up all the knowledge I could Kevin left to go to WJR. At that point, I was on my own and became Chief Engineer and IT of the eight station cluster in Toledo, which I did for 7-8 years on my own. When the position at Cumulus Detroit opened up, I applied for it and got it, but not until they found a replacement for me in Toledo.

In my career, I have also rebuilt four of the studios in Toledo and had the pleasure of helping build some state of the art facilities like the new Westwood One TOC in NY, the Nash Nights Live Studio in Nashville, TN, and 16 new studios in San Francisco, CA.

Before I got into broadcasting, I was a Chef and still love to cook.

The best advice I was ever given: to be a good engineer, you don’t have to have all the answers, you just need to know where to find them.”
