Two signal identification

Post by luc4sss » Sun Jun 10, 2018 2:20 pm

Hi,
I've now connected my RTL-SDR dongle to a V-Dipole on the home roof, and i'm receiving some new signal in the NOAA band...

The first, it's at 137.8MHz, and appear like 4 pulse every 10 seconds on GQRX...
The second has stopped to appear in GQRX when i've start to write this post...so i will update the post later...

The screenshot of the firs signal attached...
Could help a I/Q record file?
Maybe it's some ORBITRON sats?

Possibly ORBCOMM satellites. See if this decodes anything https://www.coaa.co.uk/orbcommplotter.htm.

Hi, thanks!
Unfortunately i'm under linux, so i can't use OrbcommPlotter ever with Wine due it does not accept ad audio file like input...only audio playback...

By the way, i've found the second signal...
Maybe is that the real ORBCOMM sat...
