WWBB Blanketing Contour Map
Aaron Read RIPR

(Update 02/03 5:00pm) B101 has officially moved to One Financial Plaza (aka Hospital Trust tower) in downtown Providence as their new permanent home.  A "license to cover" has been granted by the FCC

What does this mean for your listening to 88.1FM?

If you live within approx. 1.5km of One Financial Plaza (see map at right) and you are experiencing blanketing interference to RIPR, then the FCC rules (47 CFR § 73.318(b)) mandate that WWBB must "satisfy all complaints of blanketing interference which are received  by the station during a one year period."   That period began 1/27/2015 and ends 1/27/2016 but please don't delay!

You can contact Troy Langham at (918) 664-4581 or FCCcontact@clearchannel.com to log a blanketing interference complaint and request assistance from their engineers.  Make sure to mention it's under "FCC rule section seventy-three dot three-one-eight".   Give your name, physical address, and a way to contact you (email or phone).

Also, please take a minute to fill out an RIPR survey about blanketing interference.  It will help us define the scope of the problem and provide useful info for our discussions with iHeartMedia's engineers and corporate offices.

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".

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.   

THIS WILL NOT IMPACT OUR 91.5 OR 102.7FM SIGNALS, NOR OUR WEBCAST.

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.
