Enable the satellites plugin and make sure it updates the orbital elements (it should do so automatically.) Since I have an older video card, I have to use the 0.12.x series. Next you need a program to tell you where and when the satellites will pass.
WXTOIMG IMAGE SLANTED FREE
It's free but you can pay for more features if you want. I managed to find a program called WXtoImg that can decode by sound instead of pre-recorded files.

I also would've appreciated a sound sample so I could positively identify it, so I've included one. LRPT is a Russian digital (but low-res) format. Turns out the signal is actually called APT. I tried to look up what LRPT looks like on, but there was nothing. It's a good thing I didn't just wait for a signal, because I would've missed a great pass. I didn't see anything when I tuned there, so I checked Wikipedia and it said that NOAA-18 is actually on 137.9125 MHz, having moved to that frequency in 2009. The funny thing was, Stellarium reported it as transmitting on 137.1 MHz. Later, NOAA-18 made a pass and I managed to tune it in. It was too weak, so I didn't get a good decode. I did manage to capture a weak signal of NOAA-19's analog broadcast. I will if necessary, like I did with GNURadio and ATSC, but I really prefer live audio-based decoders. I don't like having to record, transcode, feed IQ into complex software, etc. My favorite radio projects are those that accept an audio signal through Stereo Mix and decode it live. Unlike what I first expected, it's not hard to capture weather satellites, even though some online tutorials might look hard. That's OK, because I didn't even see anything on the HRPT frequencies when NOAA-19 passed by this afternoon. I'm particularly interested in the digital HRPT signals, but since I'm not fully set up for that yet, I had to settle for the analog one.

With it, I've been able to receive broadcast FM, 1900 MHz GSM, and everything in between. This is my go-to antenna, offering great performance on VHF and up.
WXTOIMG IMAGE SLANTED TV
Tonight I was able to capture the low-quality analog signal.įor this and most of my other experiments, I used TV rabbit ears. This was one of my considerations when I chose the SDRPlay, since the high-quality digital mode is 4 MHz wide. I've been wanting to capture weather satellite signals for quite a while.
