TheEC: $18 Million Dollar Typos

The RIPR AudioVault

  This time on The Engineer's Corner, I want to look back three weeks ago, and look back over fifty years ago.  And how little typos can have a big impact when it comes to engineering.

TheEC: FullChannel Proves Imitation is the Highest Form of Flattery

Our good friends at FullChannel cable, available to residents of Barrington, Warren and Bristol, are not only nice enough to put RIPR's audio on channel 799.   But also their engineer, Jamie Griffin, has started his own "Engineer's Corner" email newsletter for cable TV folks.

TheEC: Prison Radio

A recent article in the New Yorker about radio in prison piqued my interest.  Besides providing a window into a world that many of us know little or nothing about, it caught my eye that these Sony SRF-39FP ("FP" for "Federal Prison") radios are actually remarkably good receivers.

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.

TheEC: Browser Extensions that Spy on You

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.

TheEC: Digital "Chirps" on 88.1

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.

TheEC: 1290AM Heard 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!

TheEC: 91.5 is Back On the Air

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.
