This Week In Radio Tech (TWiRT)

Like many of us broadcast engineers, Bob Burnham built an audio mixer and started broadcasting from his parents’ basement. Indeed, if it weren’t for basements, garages, and kitchen tables we’d likely still be in the technology Dark Ages! Bob’s engineering experience ranges from a 10-tower AM directional station, through a few other AM directionals, FM stations, on-air work, and building studios at a broadcasting school. Plus, Bob founded BRC Broadcast Services, which offers Old Time Radio shows for nostalgic enjoyment - even if you’ve never heard these great shows before.

Show notes:

* BRC Broadcast Services and Old Time Radio shows

* For analog mic cable, Bob prefers Canare Star Quad cable.

* A good technical explanation of the Star Quad cable design

* Bob mentioned WHFR and points us to their live stream on the WHFR.FM website

The Public Radio Engineering Conference (PREC) is on! Two full days of technical sessions and reconnecting with broadcast engineers from Florida to Alaska. Tech presentations included sessions on Recovering from Hurricane Ian, Virtualizing most of Minnesota Public Radio, Understanding Loudness by Understanding LUFS, Using AI for FM Pattern Studies, and the benefits of captioning radio programming. We pulled a few presenters away and got their thoughts on broadcast engineering projects and challenges today.

Quite a few radio engineers first met Paul Jellison just outside his house on 21 acres, right next to a 747 foot Blaw-Knox diamond-shaped tower. Paul lived in the house on the WLW transmitter site for a dozen years, raised his children there, and proudly gave transmitter tours to many curious broadcasters. From 4-POTS-line remote broadcasts, to the first ISDN connections in Central Florida, to new STL and remote monitoring solutions, Paul loves to use innovative technology to make radio sound better and be more reliable.

Show Notes:

* WLW, Cincinnati

* WLW’s 50,000 Watt Transmitters - YouTube video

* WLW Super Power Transmitter Tour from 1985 - YouTube video

* Paul Jellison shows us 50 kW leaking out of a loose screw - YouTube video

Sometimes broadcast engineers get to build new transmitter sites or facilities. Usually, however, we’re tasked with rebuilding existing sites or improving them. Chris Tarr is a sought-after engineer thanks to his experience and hard-earned wisdom in best practices as well as clever solutions. On this episode of TWiRT, Chris shares this wisdom and the reasoning behind it from several transmitter site projects. Plus, Kirk presents Chris (and our audience) with three scenarios for new studios and FM/HD transmitter sites, and awaits Chris’s judgment!

Show Notes:

* Chris mentioned the Bird SA-6000XT Site Analyzer - It’s discontinued but here’s a video about calibrating it before making measurements.

* The Bird Site Analyzer is easily found for sale - used and/or refurbished.

* A well-equipped RF engineer may have this current model from Bird Electronics.

Chris Tarr and Scott Fybush both had busy days! Chris is working with a tower crew, installing a 2-bay FM antenna in Madison, Wisconsin, for WSJY. Meanwhile, Scott just returned from WLYK, Saint Vincent, New York, where this Class A FM station is under new ownership. Scott’s installing new EAS gear and revamping the transmitter site where the automation system is co-located. Plus more AM transmitter sites are becoming worth more for the land than for the signal, and the station brokerage business is not doing badly. Stay tuned for Scott’s comedic announcement at the end of the show!

Show Notes:

* A new translator installation for WSJY-FM

* WLYK-FM - Up to date info from Wikipedia

* Scott Fybush makes his NYC comedy debut at Greenwich Village Comedy Club, March 6th

Keira Connolly got started in radio engineering the same way many of us did - through building our own transmitters and broadcasting to the “neighborhood”. Keira’s radio “neighborhood” may have involved some impressive FM power output levels, but certainly involved consulting broadcast facilities in both Ireland and South Africa. And now that broadcast infrastructure is moving into IT hosted systems, including virtual machines and, soon, containerized software, Keira is working with those technologies, too.

Show Notes:

* Planet Radio in Ireland

* Synergy software allowing control of multiple computers with one keyboard & mouse

* Chris reminds us of UPS battery maintenance and timely replacement. Here’s a guide.
