New Raspberry Pi OS installations no longer create the "pi" user account
You can always create a 'pi' user. Linux is multi-user.

I welcome this change. I am glad they have made provisions for those of us who either run headless or without a window manager. As stated, having a known user 'pi' is not a great risk, but in so doing

Current List of known-working handhelds for 1200 baud TNCs?
There are also purpose built HATs like https://nwdigitalradio.com/products/draws%E2%84%A2 that don't have the audio transformer issues (especially when you want to move beyond 1200 baud).

Getting the Pi to get accurate time for XSJT-X
You can get even better time accuracy if the GPS support PPS and you have it hooked up to a GPIO on the Pi. Adafruit and NW Digital Radio have HATs that support it.

Another option for NTP is the chronyd program. A GPS can be added for a STRATUM 1 time source.

Maybe a dumb question?
That's a complex question. There are virtually no limits to how many connections can be made. The factors include what webserver are you running, what applications it is trying to support, etc. How ma

Burning PiGate images with Win32 Disk img
Doesn't sound right -- how are you decompressing? You may want to try the actual Raspberry Pi imager. https://www.raspberrypi.org/software/

How does one get ALL the info?
That would be a major project and would require continuous update and maintenance on the order of the ARRL Handbook. Including a 'marketing campaign' to let people know about it. You would still have
