Description[edit]

An overpowering signal at 149.5mhz of varying bandwidth, i believe this comes from a small governmental/utility looking building with a gated road and a mast with a j pole looking antenna if i remember right the building does not appear to have any sensors on it but it is right behind a large government owned trench we use to prevent flooding

I plan to upload images of the building when i get a chance to

I currently use a passive filter to remove this signal that creates lots of reflections and have always been curious what it was or how to decode it!

Antenna[edit]

137.5MHZ QFH as captured but just as powerful on a discone, FMFrequency Modulation antenna, even a tuned 780mhz antenna (its just very strong)

IQ[edit]

You can get the IQ zipped from here [1] (it's too large to submit here)
