That's a very common "Part 15" frequency. we once had an impromptu local contest to see who could the most number of signals. Weather stations, you name it. BTW, I think I can hear well over 100 at m

That's good to know about the 10 mW range. I built a Ramsey Electronics FM stereo transmitter that is spec'd at 10 mW, and I can hear it on my car radio at one mile. The Ramsey's transmitting antenna

Thats in an ISDM, Industrial Scientific Data and Medical, band. The number of devices you will hear around there is in the millions. A few of the most common frequencies are 433.925, 434.000 and 434

Yes, but that would be "Ham" application, and not relevant to RFI. Hearing a Ham on a Ham Radio in the Ham band doing Ham stuff is no biggie. Hearing 27,217,984 unknown low powered devices with vari

Yes, but that would be "Ham" application, and not relevant to RFI. But it is if it's the link hearing the other signal. Looks like that specific frequency is a very bad one for a link. I know of at l

Well, that is one option... They operate within a wide ISDM band. Do a search for the 430 MHz ISDM band, I do not recall off the top of my head, find the range, then search it on a scanning receiver
