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.

Listen to HD radio with a $30 RTL SDR dongle
From https://github.com/markjfine/nrsc5-dui#maps :
> Maps: When listening to radio stations operated by iHeartMedia, you may view live traffic maps and weather radar. The images are typically sent every few minutes and will fill the tab area once received, processed, and loaded. Clicking the Map Viewer button on the toolbar will open a larger window to view the maps at full size. The weather radar information from the last 12 hours will be stored and can be played back by selecting the Animate Radar option. The delay between frames (in seconds) can be adjusted by changing the Animation Speed value. Other stations provide Navteq/HERE navigation information... it's on the TODO 'like to have' list.
Is this an easier way to get weather info without Internet than e.g. Raspberry-NOAA and a large antenna?

I get good NOAA images with my DIPole. Should meteor look any better. Here are pictures of NOAA and METEOR. What is with the black and blue lines?
Here is the pic of the software setup. I have also used this on my computer using vmware and https://github.com/jekhokie/raspberry-noaa-v2. It handles all of the conversions and scheduling. I just had to play around to get it to setup on a non raspberry device. I included in the ticking system there how I did that.
-
using Raspberry-NOAA-V2 the METEOR-M 2 (like bellow) images are coming out fairly decent, but all the NOAA images aren't really working. why could this be?
I'm using raspberry-NOAA-v2 to automate the whole process, so yes I think it does do it via the command line.

Need help troubleshooting NOAA receives
I'm using raspberrypi-noaa-v2 to schedule and run NOAA and Meteor receives. I've got a brand new rtl-sdr-branded receiver and a bias-tee powered LNA, and am using the v-dipole antenna configured as instructed. My runs never show more than apparently random noise overlayed on the map. Can somebody help out a newbie to NOAA reception?
-
Bad Signal? I get no picture this is the audio and picture.
I have been using https://github.com/jekhokie/raspberry-noaa-v2 and i get the same kind of pictures. On this one i used SDR Console. It handles all the connection info and frequency/dopplar.

Christmas gift(s) for hubby who always wants to “make something”?
Buy that, introduce him to /r/amateursatellites, and have him use this (plus his existing raspberry pi) so he can receive weather pictures directly from passing satellites! I and others on that subreddit would be happy to help if he needs it.
