TWiRT 704 - Dogs & Cats Living Together with Larry Janus

Larry Janus is no stranger to broadcast engineering, but his passion is excellent design of vacuum tube based audio circuits, and then controlling their functions using modern control electronics via WiFi. This passion leads to a clever integration of a tube-based mic pre-amp, fully remote controlled using a phone app over WiFi.  This arrangement gives rise to some interesting and convenient possibilities for stage-placed mic pre-amps with remote control. Larry Janus joins us from his well-equipped home lab in Florida.

TWiRT 703 - New Station, Big Turn On!

Low Power FM radio is intended to be a community service. It’s for giving the opportunity for diverse thoughts and voices to spread over a community.  However, it’s perfectly OK to have some radio fun in the process! Andy Denoncour, Frank Licata, and Grady Moates each played key roles in getting a new station - WGGG-LP - signed-on and serving the village of Ossipee, New Hampshire. The host and guests all agree that there’s a thrilling excitement to turning the radio transmitter ON for the first time, hearing your audio programming, and taking a drive to check out the coverage! 

Show Notes:
Ossipee 102.3 - WGGG-LP
On an upcoming episode, we’ll talk with Grady about advances in the HEBA antenna.

Guests:
Andy Denoncour - Engineering & Support at Comrex Corporation
Frank E Licata - Founder at WGGG-LP, Ossipee, NH

TWiRT 702 - EAS at the Edge with Bill Robertson

U.S. Broadcasters are required to provide emergency alerts to their audiences, but many radio stations use IP-based signal distribution — something incompatible with old-style EAS boxes. What is needed is a simple way to interface the real-world over-the-air reception of EAS events, filter and process the messages, and — if necessary — incorporate the alerts into the modern audio-over-IP (AoIP) air chain. Doing this right involves some innovation, but once done well, there are several distinct benefits. Bill Robertson from Digital Alert Systems joins Kirk Harnack to explain how this award-winning implementation works, and why it makes EAS better and more effective.

WIth over 60 radio affiliates and many thousands of listeners depending on high quality, live play-by-play, it’s Tim’s responsibility to make sure these broadcasts get from the stadiums and arenas to the Vol Network headquarters and beyond. Effective planning is essential! And this planning discipline works for other broadcast engineering tasks, like transmitter replacements. Chris Tarr adds his own experience and expertise to our discussion.

TWiRT 700 - High Tech Home Studio with Marc Haycook

Marc Haycook is a problem solver! He needed to add a VO studio to his home, but new construction or expansion isn’t allowed there. He needed a studio that could be moved around for access and maintenance, but not on wheels. He needed access to phones, Internet, electricity, but had to keep neighborhood and household noise out - completely out. And he even had to silence the A-10 Warthogs and other aircraft that fly over at inopportune times. The solution? Well, that’s what this episode - number 700 - of This Week in Radio Tech is all about. Voice-over artist, Marc Haycook, joins us for a fascinating look at his home-built, home studio, with the cleanest audio anywhere. Plus, we take out first phone call ever on TWiRT!

Show Notes:
