Considerations for a long-running Raspberry Pi
I've been running a bunch of Pi's for years now, and the biggest problem I've had is the Pi itself dying: 24/7 usage is hard on a small device. I've also found that stable power is essential, and to that end I've always used 5v 3a branded power cubes, plugged into a pure sine wave UPS. Choice of micro-SDHC cards is important and I ended up getting ATP industrial cards (https://www.atpinc.com/products/industrial-sd-cards) - expensive but really long-lived. Finally, using RPi-clone (https://github.com/billw2/rpi-clone) on a regular basis has been a life-saver. I clone to Sandisk Extreme micro-SDHCs and can recover from an outage in minutes.

Boot Pi4 from an SSD, not the MicroSD card
I would normally use the Pi SD-Card copier to duplicate the SD-Card to an SSD but I'm unsure if this is available on the Ubuntu image - you could possibly use this program [Github] if you are not keen on using dd with a running system.

Help needed on setting up Pi to boot from SSD
Then you will need to clone the SD to the SSD, you can use many tools that are available from your desktop computer or you can try with rpi-clone, just connect the SSD with Pi booted from SD, stop any possible service/docker to prevent any copy error and run, adapting device naming but usually will be (check device with dmesg):

Help needed on setting up Pi to boot from SSD..
I used rpi-clone, it was super easy. Whole process took 10 minutes. https://github.com/billw2/rpi-clone
- I wish I wouldβve switched to SSD Boot years ago
- Is it possible to convert an bootable sd to a bootable usb-ssd?

Upsampling in Gnuradio is necessary?
In gr-dtv transmitter examples for Gnuradio, I see some times people use a resampler block before the RF hardware sink. Say our sampling rate is ~9.14Msps which satisfies the Nyquist criterion because our samples are complex numbers.

Capturing FM using SDR
2.1. Thanks for that tip, I forgot that I was able to check the source code of the WBFM Receive block. As you have said, there are mostly the same. There are some differences between how values are picked. The WBFM Receive block would be a synonym of Quadrature demod => Fir Filter (decimation => Low pass filter) => FM Deemphasis. 2.3. My question there is why 10 and not 20 or 100. I understand that the idea is to reduce the sample rate asap, but what I don't understand is why those values were picked and how can I understand what would be the "correct" or "best" value. 2.4. I'm not fully understanding what you said. If I check the WB FM recieve source code the values that are supplied as the cutoff freq and transition width of the Low pass filter differ from the one of the example. The webfm would apply a sample rate / decimation / 2 - sample rate / decimation / 32 as a cutoff freq and a sample rate / decimation / 32 as a transition transition width. Calculating those values would end up in different that the ones supplied in this second example. Again, is there a rule of thumb to pick these values?.
- Hello everyone! I would like to install and run GNU Radio version 3.7.4 in order to follow along with The HackRF GNU Radio tutorial on greatscottgadgets.com/sdr/ but I canβt find prior releases to install. Can anyone help?

Multi band gfsk demodulation with Nooelec RTL-SDR v5 SDR and gnu radio
Gaussian filter is used only on the tx side, so specifying bt in the receiver makes no sense. Take a look at gfsk mod/demod blocks implementation: https://github.com/gnuradio/gnuradio/blob/master/gr-digital/python/digital/gfsk.py

Is there a way to delay a signal in time-domain?
Here's the filter coefficients used for the GNU-Radio interpolator block to get you started. This is a 7th order interpolator (i.e., 8 FIR taps) with very good performance. Each "row" of the array sets the delay in steps of sample_time / 128.
