Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Flipper Zero: Multi-Tool Device for Geeks
As someone with a HackRF PortaPack knockoff I got from ebay, I would agree that SDRs are better and cheaper than ever before. However, I think the average person will struggle with using a HackRF for more complex projects. I've used URH before, and while useful, it can be intimidating for beginners.
Also, while I like the RTL-SDR (and the price tag!), you can't transmit with it. While this isn't a deal breaker to everyone, if you'd like to clone a garage door remote, for example, you need to be able to transmit. While you could use something like a raspberry pi and rpix [0], but I think it is more work than it's worth for many. Also, multiple RTL-SDRs are required for higher bandwidth applications like ASTC TV or trunked radios.
With the flipper, I think the main draw for most is the point-click-done nature. Include the Android/iOS app and it makes it easy to configure on the go without a computer. The expandability is one of the main feature that will increase adoption over time compared to the HackRF+PortaPack which, from what I saw in the past, lacked longer-term support and regular updates and new features.

Rust SDR Amateur Radio Network Interface
HackRF One is an option. There are a number of others. Legality varies by country/frequency/power level.
Can also make a Raspberry Pi act as a transmitter (https://github.com/F5OEO/rpitx), which could hit the zwave frequency but not the zigbee one. (Also, make sure to put a low pass filter on it.)

Looking for Low Voltage (5V) High Bandwidth (144MHz-420MHz) Amp (3-5 watts)
The warning at https://github.com/F5OEO/rpitx#hardware suggests a bandpass filter will be needed but has no additional info. https://github.com/F5OEO/rpitx/issues/40 looked promising but is closed.

RF transmitter for Raspberry Pi With this project you can turn your Raspberry Pi into an RF transmitter with only a filter to avoid interferences.

Turn Raspberry Pi’s GPIO into an FM Transmitter
RPITX is the spiritual successor of your project!
https://github.com/F5OEO/rpitx
And it does work with nearly every RPi.
And unlike only doing FM (97MHz-108MHz), it can emit from an IQ datastream from 10KHz to 1.5GHz.

GNURadio for Pi?
Hey everyone, I've recently discovered that the Raspberry Pi can act as a radio tranceiver, and am hoping to use it for security research. While projects such as rpitx act as a great tech demo, they don't offer me the modularity/parametrization I was hoping for. Ideally the end state for this would be a cheaper/less effective HackRF.

How easy is it to make a pulse generator and simple spectrum analyser using arduino or raspbery pi? Which one would be easier to do?
The RPITX project supposedly can generate signals up to 1.5GHz with an unmodified Pi, though, which is interesting... a true spectrum analyzer needs a receiver end, though.

Flipper Zero: Multi-Tool Device for Geeks
>> or somewhat expensive and complex SDR
I don’t think that’s as accurate today as it used to be.
On the hardware side there are tons of options very cheaply available - iirc the flipper uses the c1100 (or a number like that) it’s a popular cheap chip and it’s well documented and interfaces easily with arduino.
More accessibly, lime mini SDRs are cheap but there’s quite a few alternatives too.
On the software side GNU Radio is free with decent tutorials - we’re not talking anything like blender levels of difficulty to adopt even if it is a complex domain.
Although on the more accessible side, urh is incredibly powerful given how easy to use it is https://github.com/jopohl/urh
I used the latter to tap into a 2 channel wireless bbq thermometer via a $10 rtl sdr and that was a breeze, an absolute walk in the park compared to when I reverse engineered the flysky telemetry system.

Check out URH.

Any methods of making .wav recordings from an RTL-SDR in SDR# usable on the Flipper?
URH can read flipperzero sub files and can export from wav to sub... https://github.com/jopohl/urh

Repeating weirdness on 1897MHz, strong signal with weird side swirls. Australia, so this range is for DECT, but it's not, is it? Captured on 60m of speaker wire, maybe that's why it's so odd?
Throw the recording at UniversalRadioHacker and see what it does with it!

CubicSDR with RTL2832U cannot set 434.650MHz sample rate
I dont have much knowledge on decoding a signal from scratch but try URH - universal radio hacker here. It might be able to do what you need.

It's useful for transmitting digital RF signals to control household stuff, eg. ceiling fans or whatever. You'd want to also look into rtl-sdr and Universal Radio Hacker.

Linux: software: auto detect digital modulation type.
Tried tool https://github.com/jopohl/urh and it does not get too much information. I am expecting to find something similar to wireshark - it can detect protocols in traffic and highligh different kind of fields in packet headers.
What are some alternatives?
