After ChatGPT disruption, Stack Overflow lays off 28 percent of staff https://arstechnica.com/gadgets/2023/10/after-chatgpt-disruption-stack-overflow-lays-off-28-percent-of-staff/
The popular developer forum is still hunting for a "path to profitability."
It would be a pity if Stackoverflow disappeared.
I personally think it is one of the best sites when looking for software solutions, help coding.

It would be a pity if Stackoverflow disappeared.Stackoverflow is total disaster.

90% of questions asked get no reply at all.
Few guys earned high ratings and monolized and locked all the chat traffic.
Questions asked get modified by so called moderators.
So if your question is laptop specified, it gets modified to be specified to computers in general.
Stackoverflow is time waster and should be avoided.
Low quality forum like Medicine is moderated by low IQ guys to keep traffic low.
Stackoverflow has no future and should be closed

https://stackoverflow.com/
Most of the time (very few exceptions) my question is answered right there. Have you ever written some code, as J.Larkin would say: 'if so show us some'.
AI programs also use google to find solutions, good and bad ones! does it know coding? should I trust AI?
Considering the funny crap my tests of AI produced I prefer a human being with experience.

Python code is as is.
My DVB-T dongle by media-tech is RTL based
but I get no signal in SDRConsole app (for Windows)
I was told I need to get
TUNER RTL2832U + R820T2 heterodyne tuning
It's not easy to verify is the offered RTL DVB-T dongle can work as SDR
and can read data from pressure/ temperature sensors ( Tire Pressure Monitoring System kit made of solar computer + 4 external pressure/temperature sensors.
www.websdr.nl works fine
as waterfall
So I would prefer Python for charting

The popular developer forum is still hunting for a "path to profitability." >>>
It would be a pity if Stackoverflow disappeared.
I personally think it is one of the best sites when looking for software solutions, help coding.
Stackoverflow is total disaster.
90% of questions asked get no reply at all.
Few guys earned high ratings and monolized and locked all the chat traffic.
And a a clearly wouldn't get a high rating and would be locked out. It would be nice if we could lock him out of s.e.d. but this is an unmoderated group so we don't have the option.
What is the frequency of the sensors you are listening for?
The sdr-rtl sticks go up to about 1.5 GHz, the normal ones start at about 24 MHz or so IIRC
I build a converter for 2.4 GHz WiFi, and have a converter I bought but never used for shortwave radio.

The problem with DVB-T dongles on shortwave is to find a dongle that
goes into the HF range. Worst of all, the ADC is only 8 nit for
receiving 64QAM. Due to the huge variations in signal strengths on the
MF/HF bands, you have to use a.g.c in front of the ADC. Alternatively
you have to use strong selectivity in front of the ADC to keep
unwanted very strong signals away from the ADC if you want to receive
weak signals.Both reasons make it hard to receive multiple
simultaneous signals at the same time at wildly different
frequencies.
DVB-T2 receivers must handle also 256QAM, so a netter ADC is required,
which might survive on HF bands without a.g.c. Have you found any
DXV-T2 dongles suitable for general reception ?
14 bit ADCs are often used to digitize the whole 0 to 30 MHz band at
once, but even those ADCs can suffer from very strong local signals.

Yes, there is so much RFI here from wallwarts, next door roof solar panels, what not.

Yes, there is so much RFI here from wallwarts, next door roof solar panels, what not.
One way to live with local RFI is to use a remote receiver located at
a low noise location and then carry the received signal over the
internet to your home.
For instance KiviSDR allows simultaneously picking up 4 signals from
anywhere in the VLF/LF/MF/HF bands and serve up to 4 different
internet user (or 4 completely different signals for a single user).
For two-way communications especially at 50 MHz and above, do not pick
the receiver site too far from the Tx site, since the sporadic-E
propagation to different sites may be different.
Alternatively have a remote controlled transceiver at your summer
cottage and remote control the transceiver over internet from your
city apartment.

You will still need a huge 2.4 GHz dish for upload...

Thank you for your excellent SDR job.
It may be too heavy to read pressure data from solar TPMS via SDR connected to smartphone via USB, Bluetooth to get data
charted
https://media.s-bol.com/3lqD12Vw2rY9/original.pdf
RF Transmission frequency: 433.92MHz
so I am looking for a solution to read pressure data directly from solar TPMS computer via USB port connected
to Android smartphone.
Connecting solar TPMS to PC via USB cable,
data pins look to be active but no drive available
So it may take some time to get solar TPMS connected to my Android smartphone for pressure + temperature data transfer
