Anybody know what this is from?? It’s on 462.6115 MHz narrow fm at 6khz bandwidth....I heard it get as high as 2500 feet and as low as 500 Sounds like a old video game and it announces its altitude once in a while. I happen to be outside with a handheld frs radio and came in and recorded it off my rsp1a and discone. It’s on or close to FRS radio channel 3. 20:04UTC in Muncie Indiana...thx

Well that is certainly intriguing! The ULS turns up three active licenses for frequencies that cover that frequency. The one close to Muncie is in Carmel Indiana. Their ULS entry shows they are licensed for a very broad 450-470 mhz. They manufacture two-way "telemetry" radios. Maybe they were testing some radio and there was just a right RF path from them to you.

That's a Glider (wind thermal/alt indicator) not sure why it was on that frequency? maybe someone was keying the mic or had some kind of remote device ?

Do u know what freq a glider would usually use?? If it happens again, I’ll switch to the gliders normal freq and see if I hear it on there also

462.6125 is likely the Real Freq aka FRS

I know a lot of frs radios drift a lot but at the time of the recording, it had moved to 462.6115 but channel 3 frs was the closest

Those instruments don't use frequency's that I'm aware of? and its not likely it would be in the FM mode anyway All I know is that your video sounds exactly like one used in a glider cockpit or maybe some other kind of flying machine ? UFO maybe ? JK JK anyway.... I think someone was probably keying there mic

If you want to hear one install Xplane or P3D and download a glider and you will hear the same thing or look gliders up on youtube maybe someone has it on there video ?

I found one the first try check it out https://www.youtube.com/watch?v=gzOzNtvpEIw dont hear the ALT announcements I know the one I was in years ago had that feature

I know it went on for about a half hour at least....I’ll check here and there to see if I hear it again. I know it must have been somewhat close to me cause I had a cheap little uniden frs radio and heard it there first. My adsb system didn’t have anything out of the ordinary on it My property has a lot of trees on so I couldn’t see anything....who knows

I zoomed in more on this last video so I don’t think it’s someone keying a frs radio cause there’s no ‘carrier’ and it seems to make its own modulation ...just my guess thou

i watched the glider video you posted and it does sound like what im getting. I have yet to hear it get over 2500 feet in altitude. I submitted it to sigidwiki but havent got a response yet. Just a few minutes ago i had 2 of them going at the same time on 2 different channels giving 2 different altitudes. May have to make a small yagi and go out back with my laptop and at least try to figure out which direction its coming from
