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

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).

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.

You can always add a GPS, and run gpsd and chrony.

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

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

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

I do like helping people and answering questions, but I do feel what Nigel is expressing when there is a pretty searchable question and it appears there is no effort to find the answer first. Some of

9600 baud is doable with a DRAWS™ HAT -- which also powers the RPi from the 12 VDC you have for your radio. There is a metal case available for the Pi + Hat. It also has a built-in GPS for time and lo
