Ways To Connect

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.

Browser Extension Adware Malware and Spyware

Taking a break from broadcast engineering this time on TheEC, and instead we'll look at the other side of my job: computers.   In particular, here's a heads-up to a recent story that's lit-up the geekier realms of the internet, but may not have percolated to your inbox just yet.  It has to do with BROWSER EXTENSIONS and how they might or might not...probably might...be spying on you.

UPDATE (Jan.10):  Verizon sent a trio of techs today to examine the Digital Lines.  They found a splice point on a pole near the Wheeler Farm end of the circuit where water had gotten past the weatherproofing.  The splice was re-done, with fresh (and better) weatherproofing sealant applied, and a weather box placed around it.

That's likely the culprit here: the problems started during the snowstorm, so probably water got in there and expanded/contracted repeatedly as the water froze and melted.  That expansion wreaks havoc with (relatively) fragile copper telco wiring.

As of 3pm we are back on our main STL.  We've noticed the volume levels seemed to have changed somewhat with this repair, too, so we're still tweaking things.


ORIGINAL POST (Jan.3): Ever since the hefty snowstorm and extreme cold on Thursday night, our 88.1 signal in Providence has been experiencing "digital chirps" now and then.  

The SummerCAM/SnowCAM  is in the RIPR newsroom, looking out at downtown Providence.  It uses Wowza-based streaming technology, provided by ServerRoom.net, which should work on most devices. 

Longwire antenna in Norway

We've talked in the past about skywave propagation, but it's cool when you heard about real-world examples of it.   Recently I've gotten several emails from "DX'ers" (Distant Reception enthusiasts) in Europe saying they've been able to hear Latino Public Radio on 1290AM all the way across the Atlantic!   

WCVY temporary transmitter
Aaron Read

As of Tuesday November 12th, WCVY is back on the air in limited fashion.   As you know, WCVY suffered catastrophic damage to its equipment and facility from a roof leak during a thunderstorm in August.   The entire space had to be gutted to the concrete walls, and new electrical wiring and drywall installed.  Much of the transmitter gear either took direct water damage (e.g. electricity shorting out) or took indirect water damage (e.g. rust and other corrosion), and eventually a lot of it failed completely.

We have put a temporary setup in place with a donated 30 watt transmitter on loan (with the antenna array's gain factor of 2.1, it's really more like 63 watts of Effective Radiated Power), and a special radio that's tuned to 102.7FM (there's a high-gain FM antenna on the rooftop tower) and puts out the composite signal directly into the new transmitter.   This effectively makes 91.5 into a "repeater" of 102.7FM.

UPDATE 01/21: Multiple letters sent with no response, and the pirate's still broadcasting.  A letter has been mailed to the FCC's Enforcement Bureau.   If you are an RIPR listener to 102.7 and you have experienced interference due to this pirate, you can submit your own letter to the FCC as well.

UPDATE 12/19: The pirate has been found!  Well, we're pretty sure we have found the pirate.  Using a directional antenna and a signal meter, we triangulated the position to a house a few blocks from the Locust Grove Cemetery in South Providence.  

A letter of notification of interference to RIPR was mailed to this address several weeks ago, but apparently this pirate doesn't care as there's still an illegal broadcast on 102.9 from this location.

UPDATE 11/5: Thanks to a fellow engineer who informed me there is a pirate broadcasting on 102.9FM and that is likely the source of the interference people have reported (see below).  Quite possibly the atmospheric changes made it worse, but the bulk of the problem is likely the pirate.

As all RIPR fans know, we are an NPR member station.  That means we get a lot of our programming from NPR, the BBC, and other providers, via our satellite dish.   The dish is medium-sized as dishes go, but it’s pretty big in real terms: 3.7 meters (12ft) in diameter.   There’s quite literally nowhere to fit a dish that large at our studios in 1 Union Station, so instead it was installed out at our 1290AM transmitter site in North Providence (we still own 1290, but we lease it to Latino Public R

Sharp-eared listeners may have noticed some announcements this morning on RIPR, having to do with our FCC broadcast licenses.  In fact, listeners to every radio station in Rhode Island, and all of New England, will be hearing similar announcements today.   It’s because every eight years, AM & FM broadcast licenses expire and must be renewed; these announcements are required by the FCC as part of that process.

WCVY no ceiling tiles
Aaron Read

When you’re a broadcast engineer, you get used to receiving calls at odd hours proclaiming things that tend to fall outside the bounds of “normal.”   It’s just the nature of the job.   But even your intrepid engineer can be surprised sometimes.  Friday morning, August 23rd, was one of those times. 

That morning I got a call informing me that WCVY, our 91.5FM signal for much of Kent County, was off the air.

Why was it off the air?

The roof collapsed and rain got in.  

Say what?

Air conditioner
Aaron Read

Air conditioning.  Cool heaven for those who have it, blazing hell for those who don't.  It didn't used to be terribly common in broadcast engineering, but it's become moreso in the last ten years.  The reason is that, more and more, audio processors, RDS encoders, audio encoders/decoders, studio/transmitter links, remote control systems, and even the transmitters themselves, have all become increasingly "computer-like" with IC's, hard disk drives, power supplies, electrolytic capacitors and the like.   All things that fail quickly when operated in temperatures above 80 or so, and the warmer it gets, the faster they fail!

We were happy to be a part of the Newport Jazz Festival this weekend. Our tent was right next to the stage, so Chief Engineer, Aaron Read set up a camera looking out over the crowd and captured this time-lapse video. Thanks to everyone who stopped by to say "Hi!"

Most people have heard of the "Three Mile Island" nuclear power plant accident of 1979.  But it's famous among engineers for being a "normal accident", in that there wasn't any one thing that nearly caused a meltdown of catastrophic proportions...it was a series of little things inside a highly complex system that all happened as part of "normal" operations.   None of which, by themselves, was terribly problematic.  But they all happened at once, and that was a problem.

TheEC: Phantom Power

Jul 12, 2013

BOO!  This time on the Engineer’s Corner, we’ll talk about PHANTOM POWER.   Usually not as ghoulish as one might expect, phantom power has to do with microphones.   Specifically, some microphones have active circuitry inside them.   That means they need power to operate, but it’s unwieldy to run a separate power cord and audio microphone cable.   So a phantom circuit is used to provide DC power on the same three wires (positive/hot, negative/cold, and ground) out to the microphone that the audio from the mic also uses.

A phantom circuit is one of those nifty things in electronics that looks, to the layman, like it can’t possibly work...but it does anyway.  

TheEC: Time Delay

102.7FM transmits in HD Radio

This time on the ENGINEER’S CORNER we go back in time – none of Doc Brown’s famous DeLoreans needed!  Actually, it’s about TIME DELAY, specifically, the time delay on 102.7FM in Narragansett.
