I am looking to get an RTL-SDR for my father for christmas. Is there an SDR program that I can kind of "set it and forget it" for him? He just wants a basic scanner that scans weather and nearby emergency services.
If your area is P25, then https://github.com/robotastic/trunk-recorder with https://github.com/chuot/rdio-scanner makes a great setup.

Software Choice
This is the answer. I use this program and it works great. May also want to get https://github.com/chuot/rdio-scanner as this will let you pick and choose which of the monitored talkgroups to listen to, queue up the messages so you're not hearing a bunch of stuff at the same time (or missing things altogether), and lets you go back in time. It also has a great mobile app that you can setup if you want to listen when away from your PC.

timestampSDR
trunk-recorder can do this https://github.com/robotastic/trunk-recorder while originally designed for trunked systems, it can handle conventional systems as well. Which pairs nicely with https://github.com/chuot/rdio-scanner which provides a nice web/phone app interface to listen to, that includes the ability go back thru a call archive.

SDR APCO25 Phase 2
Then use this as a front end with trunk-recorder. Both are in docker images and run 24/7 no issues.

Using a Raspberry Pi without a GUI to stream scanner audio to a phone
https://github.com/chuot/rdio-scanner is a great alternative if you don't want to stream to one of the public options and it has a plugin for trunk-recorder and a mobile web app.

RTL as a public safety scanner?
You can use Trunk Recorder to record signals and RDIO Scanner to play them as they are captured. That will only work if they are all in the passband of the SDR, but you can use more than one SDR with it.
-
Police scanner
Trunk -recorder and 2 or 3 RTL-SDR's will work well for P25 and analog trunked systems. Rdio Scanner is a good web interface for trunk-recorder that will let you stream the audio over the internet.

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.

macOS SDR
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.
