How to identify the signal I received every second

Post by lawleo » Sun Aug 18, 2019 9:48 am

I moved to a new house recently and I find that a straight signal received on my radio every second. Can anyone tell me how can I find the source of these signal? I guess it should be some sensor reporting it's reading but it seems jamming the FM band signal.

Have a scan around the air, marine and CB bands to see if there is any overly strong signal that could be overloading the dongle.

:o is that not the Radio Band?
Normally nothing is permitted to Transmit there.
I guess some electrical Device like a TV, Fridge or what ever.
Try to unplug everything and see.
If you use a Laptop try to move outside and see its there to.

I have a clock/thermometer that is generating the exactly same noise burst. It's affecting any receiver within a meter. Try moving you dongle and/or antenna.
