• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Some consumer electronics products put out junk that sounds like alternating tones on 243.0.
ELTs make a down-swept siren sound.

Likely an (older) ELT, probably activated by mistake, but you never know. Are you also getting a signal on 121.5?

If you're in a dense area, it's unlikely that there's a plane crash that no one else knows about. But if it;s a false activation, that can interfere with legitimate SAR activity if there is an emergency. So it's worth reporting. It's not a bad idea to call the nearest Coast Guard office and let them know what you're receiving and where you're located.

Yikes, never encountered that, though I have seen electric smart meters that throw out carriers near there, Good thing the 121.5/243 beacons are being phased out.

I've seen ELTs that aren't a sweep siren, though, so I think a two tone signal could still be an ELT. My advice to the original poster would be to see if the signal is still there from a different location, and if so, report it. I've reported accidental ELT activations a couple times, and the CG has always been VERY appreciative.

Was a solid tone, most likely interference from what is posted. I am in Plainview, not far from Republic. Find it odd that they allow that kind of interference on an emergency channel.
