You can do this with gnuradio-companion blocks.
Use a signal source block to generate a sawtooth wave, feed it into an

"ramp_out"). Then use a function probe (maybe call it "tuner_freq")
block to monitor the value of the probe signal

I felt inspired last night, so I added support for a description field in

of the the module. I always forget what gr-dsd or gr-ldpc do, for example.

You can run pybombs with extra verbose flags (I usually recommend "-v

it'll clean the source directories.
There's also "./pybombs inv" to see what pybombs thinks is installed.

I've seen similar messages from gqrx, but sound quality has not been
impacted. My guess is that this may be related to rapid retuning for
rtl devices, which basically involves not waiting for the PLL to lo

I'm going to guess the root cause is power:
- I recently heard some folks wishing for an external power connector
for their minis due to power issues.
- My B200 will brown out on a 6ft cable, and usually works fine on the 3ft
- My laptop will switch from charging to discharging when I push the B200

CGRAN is useful and I'd like to see it live on in some form, at least as a

github is a good way forward.

It looks like github can mirror another git repo. It looks like mirrors
don't update automatically; the docs suggest using a cron job to automate,
so if the hypothetical grad student's repository goes away the CGRAN
version could remain at the last published version.

I ran into this just last week, trying to have editable text fields for
configuration information ("hackrf=0", "rtl=0", ...) that would be store in
the config block. I ended up punting on the issue, and just hard-coding
those strings into my flow graph. Glad to know it wasn't something I did
wrong.

"Right" is whatever makes your life easy. You could only ever install
out-of-tree modules into ~/.gnuradio. You could only ever use modules
available in binary packages... Why not try pybombs instead? If you're
careful about how you set up your sources, you can probably install
everything from bina

You want a "Parameter" block, from the Variables section.

If you don't mind a write-only interface, you can use xmlrpc

You can also increase the canvas size in the top block options.

I think that's a normal side effect of some some code to allow fast
retuning and extended range by not waiting for PLL lock. Try receiving a
few local FM radio stations. If that works without dropping too many
samples or getting a steady stream of PLL errors your RTL is probably fine.
