Telos Alliance Leads the Way on AES67

When the Audio Engineering Society published the AES67 standard for Audio over IP in September 2013, it symbolized the culmination of years of development work by people across the broadcast industry. But for Telos, it symbolized not just an industry standard, but the realization of the vision of our founder, Steve Church. As such, we were proud to have been involved since the project’s inception, and have seen it through to fruition.

Always Remember... Don't Panic!

When using a 'panic dial' mode in the Telos Zephyr XStream, most noticeably with the 10baseT version, occasionally - if the 'panic dial' mode is asserted and quickly dropped - even though the first line is dropped, the XStream will keep trying to connect the second ISDN line, and that line will stay connected until someone or something intervenes. It's only happened a few times, but it can result in some expensive ISDN bills if it does.

Take no chances! Look over this HOT TIP from the Zephyr XStream user manual and implement the recommended 'safety net' suggestions.

NRSC, Let's Do This Less Often

Every year AM stations in the US must measure their transmission for spectral purity. Many AM stations say they can’t afford this. Mark Persons presents a few ideas on NRSC measurements. Plus he and Chris Tobin discuss sleuthing some really difficult interference problems.

Guide Your Audio Home with Pathfinder

In a recent blog post, Pathfinder developer Dan Bays gave us a little background on the history of Axia Audio's routing control system, and explained a bit about virtual routers and protocol translators along the way. Now Dan's back with a still more detail on this essential software suite, and explains how Pathfinder stacks the odds of proper routing of quality audio in your favor.

War Stories of 2014 - with Shane Toven

2014 witnessed some major stories, changes, and advancements in broadcast technology. Who better to talk about their implications than Radio magazine editor, Shane Toven? Shane joins Chris Tobin and Kirk Harnack talking about FCC enforcement, Rule changes, LPFM, EAS, new tech from green transmitters to IP-audio, and what we might expect from 2015.

Excellent Engineer, Wayne Pecena

Radio World named Wayne Pecena as the recipient of its 2014 Excellence in Engineering Award. Would you like to know why? Many engineers think of Wayne as their virtual mentor, and an authoritative source for learning new broadcast engineering skills, especially in computer networking. Chris Tobin and I talk with Wayne about educating engineers.

Finding Your Path with Axia

Remember that old Craftsman toolbox in your basement? Some of you may break it out every day or every weekend. For others you have to wipe off the dust and break out the manual when that construction task comes due. Axia has its toolbox too: the PathfinderPC Routing Control system. And after 15 years of projects our toolbox has grown to the audio version of the New Yankee Workshop.

Audio for TV with Gibson Prichard

How has the move to digital audio changed audio routing and workflow at TV stations? Gibson Prichard should know. He’s the Chief Engineer for Journal Broadcasting’s WTVF-TV - News Channel 5 - the CBS affiliate in Nashville, Tennessee. Self-educated in broadcast engineering, Gibson started at a local FM station and has worked through digital and HD upgrades at two television stations.

Radio Oberland Moves into the Digital Age

At the stroke of midnight on November 3rd, Radio Oberland moderators Theresa Pritschow and Simon Fritzenschaf signed off for the last time from the station's home for 22 years at Marienplatz 17. There were tears and some sadness, but also anticipation of a brighter future. The station's original analog equipment was showing its age, and it was time for the local broadcaster to move to a new location and join the digital age.

Radio Engineering at the Museum

New radio studios are always a cause for excitement. The Museum of Broadcast Communications in Chicago is home to the Paul & Angel Harvey Studio, and the newly-rebuilt Art Laboe Control Room. We’re talking with Bruce DuMont, President and Founder of the Museum of Broadcast Communications, plus audio producers, Colin Ashmead and Chris Cwiak, along with Greg Dahl, who installed the new equipment.
