(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.

ARRRR - Pirate Broadcast on 102.9FM

Close up of a whip Antenna, believed to be the source of the 102.9 pirate.

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.
