I monitor the satcom band from 240 - 270MHz every day at some point. So I am familiar with what tx are in that range. Since Nov 2023 I've been receiving wbfm transmissions in the 240 - 300MHz range. These transmissions are not pirate satellites in the fm mode; they are local and consist of phone calls, music playing. I'm pretty sure they are coming from vehicles as the transmissions refer to stopping for gas, getting groceries, picking someone up for work, etc. They are brief from a few seconds to sometimes several minutes. The busiest times I rx them is at the change of work shifts in the am and pm hours. I know bluetooth operates in the 2.4GHz range and are digital; but I have heard "bluetooth connected on a lot of the transmissions". If you listen in the fm mode the transmissions are garbled. Does anyone know if there are analog bluetooth units that people would use in their vehicles that tx in this range?
They are not harmonics or images. I hear them on several different scanners that can rx wbfm. Everyday I can count on hearing the same frequecies being used and there are over 30 frequencies that I rx and seem to be spaced 25KHz apart. If you can rx in that band in the wbfm mode, I would like to hear if anyone else is receiving transmissions like these. I can pick them up while mobile in my suv while driving around the County here in Berks, PA. Thanks for any info you can provide on these transmissions.
