Listen to HD radio with a $30 RTL SDR dongle
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.

WebSDR – internet connected Software-Defined Radios
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.

SDR and software for Mac
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.

Just got an RTL-SDR, what kind of fun stuff can I do with it?
SSB/CW (also (W/N)FM/AM/Raw) using GQRX

what kind of device could I listen to 900mhz radiowave transmissions? I want them very specific like 943.147mhz
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.
- GQRX on older Mac?

Crossfire low range?? RX Loss & RSSI DBM?? Beeps??
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/

Looking for a good AM/FM Radio sollution
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.

SDR over Ethernet - Anyone tried it?
A network protocol called rtl_tcp that has been ported to rsp_tcp by the guys at SDRPlay in order to increase the IQ bandwidth from 8 to 14 bits to get the most from their SDRs. SDRPlay has provided a rsp_tcp server app/image that can be run on various hosts including RPi. Your RSPxx SDR connects to the RPi via USB and the RPi connects to your local network via Ethernet or Wi-Fi. Any network client application that supports rsp_tcp/rtl_tcp (including SDRUno) can connect to the RPi and use the SDR just as if it was connected via USB. This not only allows you to use your SDR from potentially anywhere you have a computer, it also allows you to minimize the distance between the SDR and the antenna(s). In theory you could even run Ethernet cable right up to the antenna.

What's a good Linux-compatible multipurpose decoder of RF signals?
For remote-location of an RTL dongle using Raspberry Pi or similar, which linux or windows clients can connect to over wifi or ethernet, there is rtl_sdr

How does sample rate work in an sdr
Hmm. I'd check out the RTL-SDR Sourcecode, in particular rtl-test, and manpage. This tool lets you calculates the PPM error of your dongle.

Raspberry Pi controlled radio telescope.
Not sure if it’s exactly what you want, but you can control GQRX over TCP. If you want more granular control, you can use the rtl-sdr library to process your desired signal. In my opinion it’s a bit low level for your project so using its Python wrapper, PyRtlSdr so you can get most of the rtl-sdr functionality while using Python’s networking.
