Technically Speaking…


Technology plays a crucial part in the daily operation of WBHM. As program director, I don’t have to understand the nuts and bolts of how a piece of equipment works or know how to fix it. But I do need to have a big picture idea of how something works. Sometimes I feel like I’m the universal translator form Star Trek – I’m bridging the gap from the engineering side so I can ensure the on-air staff has the tools they need to do their jobs as efficiently as possible.

Here are a couple of interesting tech tidbits from WBHM told in a (hopefully!) not too tech-y way.

Tape is a relic of the past. All local content on WBHM is now recorded on hard drive. We’ll do an interview in a studio (or in the field), export the file, digitally edit the audio at our desktops, and then import that audio back into our system.

And tape used to be edited with a razor blade and a grease pencil! It was physically cut, so if you made a mistake, well…there wasn’t much you could do about it. We now edit digitally and in addition to listening to the audio, we can also “see” it on our computer screens. More importantly, if something doesn’t sound the way we like, we can just click “undo”.

WBHM receives some of its programming via satellite. That’s probably not a surprise. But did you know satellites are 23,000 miles up in space? A program like Morning Edition is produced in Washington D.C., uploaded to a satellite in space, and then downloaded to WBHM’s satellite dish right outside our building. Even traveling at the speed of light (186,000 miles/second) there’s just about a half-second delay. That may not sound like much, but in radio, timing is everything.

At WBHM, we have two clocks in our satellite room. One is labeled “NPR time” and any direct mission critical on-air component synchs to this clock. The other is known as a “GPS clock” (global positioning satellite) with time provided by the U.S. Naval Observatory. These two clocks are ever so slightly different. Why two clocks? In a word, redundancy. Technology works great…until it doesn’t, so we always need a backup plan.

(Through “Programming Notes,” we hope to keep you connected to what is happening at WBHM both internally and on-air. Have feedback you’d like to share? Or a programming question? Let me know!)


Deliberate Indifference – Inside Alabama’s Prison Crisis

You’ve probably heard of our new narrative podcast, Deliberate Indifference. And, given all the heavy news the past few months alone, you may think this is the last thing you want to listen to. I urge to reconsider. As citizens, we have a right to know how more than 500 million of our tax dollars […]

What’s in a name?

Every so often, I hear from listeners who politely (or sometimes not so politely) take WBHM to task for mispronouncing words. As Program Director, it’s my job to make sure we sound not just consistent on the air, but credible as well. Whether it’s a classical composer or name or place in the news, this […]

Summertime and the livin’ is easy…

To say the news has been very heavy lately is an understatement. With that in mind, I want to take a moment to pass along a few different things that are just fun this summer. Thanks to the popularization of plant-based diets, vegan (non-dairy) ice cream is gaining popularity, and there are interesting new flavor […]

The Only Constant Is Change

There’s a small program change coming to WBHM. On Being, which currently airs Sunday evenings from 6 to 7, is ending production as a radio program and transitioning to a seasonal podcast. The final episode will air on WBHM Sunday, June 19th, and you can read more about this change from host Krista Tippett. But […]

More Driveway Moments

A little over a year ago, I wrote about driveway moments – those times when you’re listening to WBHM in the car, you’ve pulled into the driveway, you might have even turned the ignition to accessory, but the story is so good you just can’t bear to get out of the car. Well, this week, […]

I’ve Got “It In” For You!

Last week’s column There’s No Leaving and There’s No Returning prompted some good feedback. A listener wrote to tell me another phrase they find irrelevant is “in for,” as in when I host and say, “I’m Michael Krall in for Andrew Yeager.” Their thinking is that it’s unnecessary because if you hear a program enough, […]
