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.

Embedded Systems Weekly #128
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.

Create a subghz file from known data?
For example, rtl_433 has the spec for an X10 sensor say I know what data I want to put where, is there some tool/site I could enter in what the "specifications" of the signal waveform are and the data I want to send as a byte-string or binary-string and it would create a playable .sub file for me?

New Guy: Outdoor Thermostat / automated fan start/stop.
For "outdoor distances" I'd probably stick to something LoRa or 433MHz based. YoLink has quite a few options using the LoRa protocol. I use basic 433Mhz based AcuRite sensors paired with an RTL-SDR dongle connected to a machine running RTL_433, and use Home Assistant to trigger automations and alerts.

Mystery signal?
866-868MHz is SRD/ISM band (in UK/EU). Can be things like energy meters, TPMS, medical devices etc. Try rtl_433 on it.

Problem trying to listen to a Honeywell doorbell (RF 868 Mhz) with RTL-433
I'm trying to add a Honeywell doorbell to Home Assistant by using the RTL-433 GitHub project/program. When I run the program the SDR dongle is detected but it doesn't display anything when I press the doorbell (the image shows what I see after running the program and pressing the doorbell). I have also tried Honeywell Activelink (FSK) aka [116], so I have tried both 115 and 116 decode protocols.
