gpredict VS noaa-apt

I didn't watch the video but Gpredict has tracking and a map showing the orbit path and ground footprint for satellites you select.

I'm using sdrpp with Doppler correction with gPredict. I record the signal in sdrpp and then process it with noaa-apt.

look at the source of http://gpredict.oz9aec.net/

Your missing the point basically they mean upgrade your software to Gpredict satellite tracking software (GPL) which has Linux and Windoze versions. http://gpredict.oz9aec.net/   Gpredict uses hamlib to control both radios and mounts. Hamlib supports many radios and mount support includes Meade, Celestron and iOptron IEQ45 alt-az mounts via AUSCOM standard software. Once done the next part is ensuring you set up you com ports to appropriately control your devices radio and mount and making sure the appropriate devices are set-up in the software. Note if your com ports change say because you replug something, don't forget to update the port details otherwise coms will fail and the relevant device won't be usable. Check out the documentation and there are a number number of set-up videos on YouTube if needed.

LWN usually has great content but they've missed out on so much free ham software in this article that I use regularly.

My main HF rig is an older Yaesu FT-950. I tapped the IF and brought it out of the chassis where it is plugged into a cheap RTLSDR. I then access that RTLSDR (with free drivers) with GQRX (free software for visualizing anything compatible with SoapySDR or GNU radio), and the result is that I get a panadapter that is arguably better than what's available on $2000 radios.

As for VHF/UHF stuff, I would be hopeless if it wasn't for GPredict on my laptop making it simple to track LEO satellites. https://github.com/csete/gpredict Short video here: https://photos.app.goo.gl/eg87BWpt2XnJdGFp7

I also run an APRS igate, which is powered by direwolf: https://sielicki.github.io/posts/radio-scanner-aprs-igate/ , https://github.com/wb2osz/direwolf

It hasn't been updated in a couple years now, but `gpredict` is a nice desktop program that will show projections of satellite orbits and predict upcoming passes.

GOES sats are geostationary but the NOAA APT satellites are encircling the planet and you can pick them up. Old tutorial but still relevant, just use "noaa-apt" tool[0] instead of WXtoImg. https://www.rtl-sdr.com/rtl-sdr-tutorial-receiving-noaa-weat...

Sometimes WXtoIMG just discards parts of the recoding when the signal wasn't strong enough. In those cases I've had some luck running the recorded .wav file through noaa-apt to get the full image.

so the NOAA_APT decoder link on your guide did not work properly, By chance did you mean this link https://noaa-apt.mbernardi.com.ar/?

So far I only use it for noaa-apt program though.

Had this exact problem, the thing that I found is that GQRX records at the wrong sample rate, which WXtoImg can’t handle. However, https://noaa-apt.mbernardi.com.ar this utility did work for me. I’ll also note that WFM is the setting I use in GQRX, not AM

You should try noaa-apt too, it usually gives better results for me.
