Lost mode in Find My iPhone

We've all been there.  Even your Intrepid Engineer has done it.  You're having a perfectly lovely day.  You decide you want to check your email, so you reach for your phone and...


...where's my phone?

...WHERE'S MY $#%%!@*^& PHONE?!?!?

Oh no, you've lost your phone. Now what?

Listening to RIPR online gets easier every day!  But since the webcasting world is constantly changing, we have to change, too! If you've got a problem hearing us on your Android phone, or you want to know what's going with the stream on our website?  Or maybe you need a little help choosing a wifi radio?  

All is revealed on our Streaming Help page at

Check it out for all sorts of helpful info on how to keep the bits flowing and RIPR on your speakers - now freshly updated by your Intrepid Engineer with new info on podcasts and NPR One!

UPDATE: More tower work Saturday April 11th beginning at 10am.

The second AT&T crew is returning for another try for antenna replacement on Saturday 4/11 starting at 10am and lasting most of the day.  

Based on previous experience, we are hoping to maintain normal operations on 102.7...or at worst just run at half-power.   Check the @RINPR twitter feed for updates.


102.7FM tower
Aaron Read RIPR

Beginning at 10:00am on Saturday March 28th there will be an extended outage of RIPR's 102.7FM signal.   It is expected to last several hours at least, possibly until sunset (around 6:30pm).

We may be able to continue operating at reduced power.  But it's likely that 102.7 will just be completely off the air.   Please note: whenever 102.7 is off, our WCVY 91.5FM signal in Coventry will be off as well.  (it gets its content via a radio receiver tuned to 102.7)

Optimod 8100A

UPDATE DEC.1, 2014: our demo unit of the BW Broadcast DSPXmini-FM SE audio processor arrived today.   It's been installed on 88.1FM and initial tweaking is complete.  The sound seems markedly improved.  I'll be fiddling with it further to adjust it across different programs.

ORIGINAL ARTICLE: About a week ago, your intrepid engineer made some changes to the airchain on our 88.1FM that should've, in theory, been wholly beneficial and with no potential for downside.  However, around that same time I started getting reports of an odd whistle...or just high-pitched static...that would come and go with no apparently rhyme or reason.

These reports aren't widespread, but there's been enough that I'm no longer inclined to think it's just an odd run of people happening to have poor reception.   The only commonality is that it seems to occur only when reception of 88.1 isn't very good to begin with.  Not necessarily "poor" reception at all, just not "super-solid".

Friday night and mid-day Saturday (Nov.14 & 15) ended up being a bit of a saga for what was supposed to be a routine upgrade for our 102.7FM signal in South County.   So first off, an apology to our RIPR listeners on 102.7FM, and to MVYradio's listeners to the 96.5FM signal in Newport.  There were several dropouts, periods when RIPR was on backup transmitter (and thus 96.5 was off entirely), or when both transmitters were down.

Exactly what happened could be described as an avalanche of minutiae, but I'll lay it out as best I can.

Aaron Read puzzles over the new NPR clocks
Dave Fallon RIPR

Starting on Monday Nov.17th, the clocks for Morning Edition, All Things Considered (both weekdays and weekends) and Weekend Edition  will be changing.  

Today's Engineer's Corner is co-authored with our Operations & Production Manager, James Baumgartner.  He and I are the ones directly responsible for organizing all the clock changes' impact on Rhode Island Public Radio, and we've put together this synopsis of what the changes mean for our listeners.

Buggiest iOS Ever?
Aaron Read RIPR

We have heard reports from fellow public radio stations that some users with older iPhones (like the iPhone 5/5S) who upgraded to the new iOS 8 are having problems listening to stations' webcasts.

There doesn't seem to be any particular pattern at this point, other than the problems started when the user updated to iOS 8.  Nor are we at RIPR aware of any RIPR listeners experiencing this problem.

If you were listening to the 8pm newscast on Tuesday night (Sept.23) then you got to experience our new service that helps make sure your watch can be set to the most precise time possible!

Okay, that's not really what happened.  The newscast started out with the USNO's "time guy" (you can hear the automated time announces by dialing (719)567-6742 in Colorado; the DC numbers don't seem to work).  

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!

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.   


Keep watching our Twitter feed for updates.

New Air Conditioner
Aaron Read RIPR

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: NAB2014 in Vegas

May 2, 2014
Andrea Toven

As promised, here are some pics of my six days and seven nights in Las Vegas for the 2014 National Association of Broadcasters (NAB) show, one of the biggest conferences in the USA, with over 98,000 engineers, managers, vendors and content creators all crammed into the truly massive Las Vegas Convention Center (LVCC).

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!
