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.

Does Spektrum work with HackRF One?
No. QSpectrumAnalyzer has some feature overlap and can use HackRF with hackrf_sweep or soapy_power.

I don't know if my HackRF is broken but anything in HF range it gets jumpy and I can't make out any specific frequency. I got the Portapack H2 on top if it makes any difference. on win10 and Mac I got the same problem, also with different antennas.
Here is some good news though: There is a way work around this sampling rate restriction. Since you don't really care about the actual data, and you're more trying to just visualize the traffic, there is a special mode that HackRF's support called "sweep mode." In sweep mode, the HackRF will rapidly re-tune the antenna across a huge swath of the spectrum to give you a birds-eye-view of a much larger frequency range. Unfortunately, CubicSDR (and most other SDR software) does not support the HackRF sweep mode natively, so you'll need to use another tool, such as "qspectrumanalyzer" which supports this view. Qspectrumanalyzer is a python application that can interface with a HackRF and work in sweep mode, giving you a view 1 MHz - 6 GHz almost once per second. Granted, you'll want to tweak this down to just the 2.4 GHz range and play with the setting to get the view just right, but it should be possible to see what you're trying to see.

How do you find a radio controller's frequency to use the hackRF?
qspectrumanalyzer (https://github.com/xmikos/qspectrumanalyzer) will do this.

Hackrf cannot capture wifi signals ?
QSpectrumAnalyzer is an example of a tool that can make use of this.

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.

What is your favorite thing to do on a flipper zero? I’m getting mine in a few days!!!
you should check out Universal Radio Hacker

Analysis tools?!?
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.
-
I can stream anything on a radio frequency
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.
