Beagle_SDR_GPS VS gqrx

If you want to have something similar for use at home, you could take a look at http://kiwisdr.com.

I have one, but you need to hunt down EMI sources, before you can properly use it.

Have you see http://kiwisdr.com/ ?

One of my favorite projects is the KiwiSDR network, which is essentially making radios available online for public use:

Your father could be anywhere and enjoy listening from... anywhere? :-)

http://kiwisdr.com/ - Online access to software-defined radios for listening and learning nomenclature as well as a useful SWL tool

find the signal on SDR, kiwisdr.com

For a book look at Gordon West's technician book, for a website hamstudy.org. If you want to listen to HF amateur radio kiwisdr.com, you can also pick up a rtl-sdr for about $25. A great You Tube channel is "Ham Radio Crash Course"

I just checked the map of receivers on http://kiwisdr.com/ and the first Bay Area one I tried (KE6GG out of Daly City, CA) seemed to be able to tune in AM and FM broadcast radio stations.

The project is http://kiwisdr.com/ Regarding closed-source software, people are reverse engineering everything anyway.

There's an issue open for this: https://github.com/gqrx-sdr/gqrx/issues/1104

I could really use some help from a software build expert. Gqrx and all its dependencies would need to be built in CI with Apple silicon support, and I don't know how to do that.

If you don't need the web interface and your usual desktop SDR software supports rtl-sdr tcp mode, you can easily set up a small board that calls rtl-sdr with the appropriate parameters so that it will wait for a remote connection from the above software, not unlike what happens with WebSDR, but you would be using your usual desktop SDR application which would be native and much more snappy than a web browser. Here's an example using gqrx.

GQRX works pretty well for me. There is also CubicSDR and SDRAngel afaik - you might just want to play around with them and see which you are most comfortable with.

SSB/CW (also (W/N)FM/AM/Raw) using GQRX

For most signals (including analog AM and FM modes) you can use a laptop with an RTL-SDR USB dongle (fairly cheap), or another SDR, and a reasonably tuned antenna. Various RTL-SDR models can tune from around 500 kHz up to 1.75 GHz with 3 mhz of bandwdith, and works with free software like SDR# for Windows and GQRX for Linux. It works with lots of other software, too, for ham modes, digital modes, etc.

Some of the Crossfire modules have a rudimentary spectrum analyzer function on them that might help you identify if there are other devices operating in the 900MHz band around that area, but I'm not sure the nano TX is one of them. I have a couple RTL-SDR dongles or equivalent I'd use with GQRX as a cheap spectrum analyzer if possible.

Good old GQRX for me https://gqrx.dk/

There is loads of software that will work such as SDR++, GQRX, CubicSDR, and SDRangel just to name a few. For HD radio reception, there is nrsc5. Nrsc5 only works with an rtl-sdr, so you will need one if you want to receive HD radio.
