TheEC: New Production Studio

Late last week I was very happy to execute the final changeover to RIPR's new PRODUCTION STUDIO.  This is a big deal for us; our studios were originally designed and constructed by WBUR, way back in the late 1990's when they owned RIPR (then just "WRNI") outright, and most of the "back office" personnel were still located in Boston.

Accordingly, we only have one "studio".  It's two connected rooms: a "control room" with the usual mix board, producer's station, director's station, etc...and a "mic booth" with just a trio of mics.   The idea was that a lot of the day-to-day, off-air, production work was happening up in Boston, where WBUR had four main studios and seven edit booths.  So the workload on RIPR's end would be pretty light.

Fast-forward to 2007 and now we're an independent news radio station with nine news staff and a ton of daily production needs.  Yet only one studio to do it in!  AAAAAHHHH!!!  Scheduling conflicts were rampant.

TheEC: New STL at 88.1FM

UPDATE 7/22: After a weekend of solid operation, we've moved out of "beta" and into "gold", meaning when you listen to 88.1, you're hearing audio that's coming across the new microwave STL.

------------------------------------------

Good news everyone!

Longtime Engineer's Corner readers know that we've had, well, "issues" with the STL or "Studio/Transmitter Link" for our 88.1FM signal in Providence.   The STL is what carries the audio from our studios in downtown Providence to the transmitter/tower at the Wheeler Farm in Seekonk.

Now a couple weeks ago we revealed that half of a new wireless microwave STL was installed, and that the other half would be installed soon.  Today, we fired it up for the first time and the results were gratifyingly positive!

TheEC: New STL Dish at 88.1 - INSTALLED!

UPDATE @ 1pm : 88.1FM is back at normal power!  Pics are available on our Twitter feed here, here, here and here.   By the way, many of these pics were taken with a stock iPhone 5S using this telephoto lens attachment.  Pretty good for $45!

----------------------------------------------

On Wednesday June 18th, beginning around 9:30 or 10am, 88.1FM will be running on the backup transmitter & antenna for a few hours to install new equipment on the top of the tower.   We must run on the lower-power backup for the health & safety of our tower climber.

The backup operates using a one-bay vertically-polarized omnidirectional antenna and about one-tenth our normal power.   

THIS WILL NOT IMPACT OUR 91.5 OR 102.7FM SIGNALS, NOR OUR WEBCAST.

Keep watching our Twitter feed for updates.

This week Frank from Logitek Audio was in town to provide RIPR with a demo of their MOSAIC mix board.  To turn a phrase, this is not your father's mix board!

TheEC: Audio Dropouts on 88.1FM

Can you hear me now?

UPDATED 5/8/2014.

The morning of April 30th saw several odd "dropouts" in the audio on 88.1FM, usually lasting 5 to 8 seconds each, happening as often as 2 or 3 times a minute, but more commonly once every 10 to 15 minutes.

There was also an odd "repeating audio" effect some people noticed, when the audio came back.

Read on for the explanation of both!

TheEC: 88.1 Studio/Transmitter Link

In light of ongoing issues with the Studio/Transmitter Link (STL) for WELH 88.1, we have implemented a new STL  schema.   If you heard a lot of odd audio dropouts on 88.1 today, that was the reason.

The good news is that we should have a pretty good temporary solution in place, and a solid path for a permanent solution is on the horizon (tentatively scheduled for mid-March).   Best of all, I was able to put in a new(er) Orban Optimod 8100A audio processor to replace the less-capable Inovonics DAVID-III.  There's a little sibilance still, so I need to tweak the settings.  But overall the sound should be much louder, fuller, and more consistent.

Read on for more details...
