On #macos #tahoe installed with #conda, I'm going slightly insane.
gnuradio (v3.10.12.0) depends on qt-main (v5.15.15)
gnuradio also depends on qwt (v6.3.0) which depends on qt6-main (v6.10.1)
So, now I have both qt5 and qt6 installed .. by the installer .. that fails when you attempt to run anything because there's two versions of qt installed.
Anyone?

Just tried installing #gnuradio on mac and even after all those years it's still a mess.
Luckily, I can just® run Linux as well

Playing around with ctcss squelch block analog.ctcss_squelch_ff(self.audio_rate, 131.8, 0.10, 0, 0, False)
It works, but sometimes short cracking noise when there is no carrier with 131.8
The default 0.01 gave continue noise, but 0.11 kills audio even if the carrier is there. Maybe the latter 3 parameters should be adjusted? Wiki block docu is limited.

1. Good department meeting with the dean today.
2. Ordered a lot of hardware for next semester’s classes.
3. Got #GnuRadio working natively on my ARM Mac with my #HackRFOne. -

Oh, it's a thing of beauty. The #gnuradio CW was maxed at 1.0 and that was overranging in my receiver. Also adding the gaussian rise/fall times helped out a lot (greasing the frequency skids).
The result: the output of the polar coordinate receiver showing a beautiful magnitude response in #Aldec #rivierapro with GNU Radio acting as stimulus. The amount of code it took to bang this out in GNU Radio (python) was far less clunky than trying to piece it together in HDL languages and should be more reusable.

Sweet! Finally got the #gnuradio and #aldec #riviera-pro linkage to work. Still don't have a handle on complete testbench flow control (it crashes after about 40 us with a Gnu Radio library error) but even this is pretty neat. I could either bolt on our receiver design (already verified but would be interesting to see the result with this stimulus), or improve the stimulus side, make it more parameterized so I can tweak it towards the tolerance limits.
But it freakin' works and that is really nice.

So very close to getting #gnuradio and #aldec #riviera-pro to work together. Now it's just a matter of libraries I think. Seems like maybe they wrote things for a different version of GNU Radio. Of course this is just the EXAMPLE. Getting it to work with my own material is probably another question entirely.

Well appears as if there's no concept of time in #gnuradio. Everything is sample based. It's understandable but means the first helper module I think I will need to write is a sample counter though to provide other modules with a concept of time.

Picked up some #whistlers from last night's #thunderstorms!
I thought I heard them last spring (storm season in the Southern Plains) but also caught their #vlf spectra last night.Spectra are produced with #gnuradio as "waterfall charts" : time on the y axis (most recent at bottom) and freq on the x axis.
Circuit was just a whip antenna with FET front end plus some amplification, and a low pass filter to remove broadcast radio, and a sharp high pass filter to remove power hum & harmonics.

The #GRCon #CTF is under way, and runs until Thursday at 16:00 EDT (20:00 UTC). There's something for everyone; no prior #GNURadio experience necessary. https://ctf-2024.gnuradio.org/ flag{go0d_lucK!}
