STLs

Tech Tips: Test a Microwave Shot at the Receive Site 

A handful of attenuators can help you set a benchmark.

Remote Access and Site Connectivity: Wireless 

Ways to solve the problem of remote connectivity.

Remote Site Access and Connectivity via Wireline 

There's nothing worse than having something bad happen at the transmitter site, and not being able to see exactly what it is. The ability to take action remotely is clearly just as important.

Prior Coordination for STLs 

No doubt, you have received frequency coordination notices. These notices form one side of the coordination process. It's up to you to follow through to avoid potential interference.

Studio-to-transmitter link

Not the Same Old STL 

Why it's so important to have network access at your transmitter site, and how you can do it now.

Field Report: Harris Intraplex HD Link 

The Intraplex HD Link is a 950MHz radio system that passes not only the typical program audio, but also HD Radio traffic between a studio location and a transmitter site.

Harris Adds IP Functions to Intraplex HD Link STL 

The STL can provide concurrent RF and IP delivery to minimize service interruptions.

Barix Extends Feature Set for Reflector Service 

Hosted by Barix partner StreamGuys, the application serves as an online center to configure and monitor the audio transport bridge while providing a relay of the audio feed.

Calculating STL Fade Margin 

Understanding the mechanics of your RF program delivery system, and maintaining a keen grasp of the associated fade margin can go a long way to diagnosing the rare, but ultimately problematic impact path failure can have.

Field Report: WorldCast Systems APT WorldNet Oslo 

Doug Irwin predicts that Oslo is well on its way to becoming one of those classic pieces of equipment that engineers will talk about for years to come.

2009 NAB Show Technology Spotlight: IP Codecs 

From the 2009 NAB Show: Insight to the IP codec technology on display at the convention.

IP-based STLs 

Many of the devices we find in a broadcast facility today communicate by way of IP; what was once kind of a luxury (LAN at the transmitter site) has now pretty much become a necessity.

Digital wireline STLs 

The link from the studio to the transmitter is a critical, but often overlooked part of the transmission system. There are generally two options: wired or wireless. There are some common reasons behind building a wireline STL system as opposed to using a radio system.

Moseley Event 5800 

I highly recommend the Moseley Event 5800 as an excellent STL solution, with a ton of expandability and bonus features.

Connecting studio facilities and transmitters 

32 Avenue of the Americas is home to one of several large Carrier Hotels in New York City, and as such was an advantageous location for our endeavor.

STL white spaces? Apparently so. 

Because the frequencies in the 700MHz band are being auctioned for new uses, these frequencies will no longer be available for auxiliary uses, such as wireless mics. This was further reinforced by the FCC's recent ruling to ban wireless mic use in this spectrum.

A break from Tradition: Using IP for an STL 

A station's studio to transmitter link (STL) is an integral part of its mission-critical transmission system, linking the site that generates the program material to the transmitter location itself. As such, the quality and reliability of STL equipment has always been of paramount importance. One critical aspect of an STL system has historically been lack of contention in its use.

Staying Connected with STLs 

With the trend toward digital audio transport, and lately data transport, a whole new generation of radio STL systems has been developed.

Applied Technology: Intraplex Netxpress 

Migrating from T1 circuits to an IP-based system is an adventure that, until recently, was not for the faint-hearted.

Top tower maintenance tips 

James Ruedlinger, a staff engineer in ERI's Structural Division, shares his observations of the top ten maintenance problems he encounters when working on towers.

Field Report: Broadcast Electronics Big Pipe 

When Clear Channel Minneapolis needed multiple T1s to handle its data, Jess Meyer looked for a better way. He found it in the Broadcast Electronics Big Pipe.

Find the missing link: Studio to transmitter links 

Engineers need to be concerned with the ability of an STL system to deliver multiple data streams over and above what we consider to be the station’s program audio to the transmitter site.
