Alternative rock radio station 99x announced Wednesday afternoon that it is ceasing broadcasting on 98.9 FM at midnight, April 11, due to a decision by the FCC.

“Pursuant to a decision by the FCC, 99x will cease transmission at 98.9 FM at midnight tonight,” the station announced. “99x will still be broadcast on 99.7 HD2, on the 99x app, Alexa and streaming at 99x.com.”

It’s not clear what the circumstances behind the decision were. Representatives of the station and the FCC were not immediately available for comment.

After the initial announcement on Facebook, the station provided a more detailed update about the situation. The FCC decision had to do with “interference complaints,” the station said.

Here is the station’s full update, published on Facebook:

Today, sadly, we received a notice from the FCC that requires us to cease broadcasting on 98.9 FM immediately. So, effective midnight tonight, passionate music mavens will have to find 99x on either their app, WWWQ-HD2 or on the stream on their laptop or desktop computer. A few things we want you to know:

1. We are pursuing the FCC with an appeal of their decision. We believe the interference complaints were remediated successfully and we have a right to continue to provide lovers of 99X with a product they have proven they love. We are not sure how long the process will take, but we will do all that we can to return 99x to the FM band.

2. This is not the end of 99x! Through the distribution channels described above, we’ll continue to program the station with the passion, the love and the effort we have. To that end we will be launching a promotional campaign on our products informing listeners on where they can find 99x
