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: Air Conditioning at 88.1FM

Regular readers of the ENGINEER'S CORNER might recall my story about air conditioning at our 102.7FM transmitter in Narragansett Pier.   Well now I'm pleased to report that we have air conditioning at 88.1FM WELH in Seekonk as well!

In many ways, this is an even bigger deal; 102.7 had a hefty vent fan system that could move a lot of air.  Sure, if the air outside was hot, it means the air inside was hot, too.  Usually you can't cool a room using outside air below about +10F degrees above outside air temps.   So if it's 90F outside, it's 100 to 105F inside...ugh!  

And at 88.1, we didn't really have even that.  The transmitter site is an 8x10ft shed with a single 12 inch desk fan blowing air out one of the wall vents, and no insulation whatsoever on the walls or ceiling.  Temps routinely broke 120F inside, even when it was only 70 to 80F outside.

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!

UPDATE 3:30PM​  Taking advantage of the downtime, we swapped in the new BW Broadcast TX300v2 transmitter to replace the aging BE FX50 & QEI/LPB FM150SS combo.   The 91.5FM signal should be a little better than usual now.

TheEC: Heartbleed and Donations to RIPR

The big news in computing this week is Heartbleed, a serious security problem with secure websites.   Specifically, it's a two-year-old bug in the near-ubitiquous OpenSSL (Secure Socket Layer) protocol...most commonly recognized when there's a "https" (instead of "http") at the beginning of a website address.

It's a big problem, and I'll explain why in a second, but first I wanted to let everyone know that the RIPR donations website is secure and never was vulnerable to Heartbleed.   They use a hardware-based implementation of SSL, not OpenSSL.

So if you have donated or plan to donate to RIPR, you have nothing to worry about in regards to Heartbleed and that donation.  Whew!

TheEC: West River Runs High Through 1290

The West River runs high through the 1290AM tower site. Water levels are a good two feet above normal.

As many of you know, RIPR owns and maintains the 1290AM site on the Providence/North Providence town line.  Our NPR satellite downlink is there, and we lease the frequency to our friends at Latino Public Radio.

In the past, the site was largely a pond (Whipple Pond) with Douglas Ave forming part of a dam in the eastern corner.   After the torrential rains of 2010, the dam broke and the pond drained.  Now the West River flows freely through the site.

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.

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.
