Re: Bizzare issue with MMDVM Hat harmonics and 5GHz WiFi

I've had/have a similar problem but came to it via a different angle: For a time, several of my hotspots would mysteriously drop their wifi connections but could not relate it to any specific activities or configurations on the hotspots themselves. But eventually, it became annoying and that's when ...

Re: Create a new pi-star flash SDcard

Your best bet is to use Etcher (balenaEtcher) to "clone" the drive from your working system. The clone can then function as both a backup and a replacement for the drive in your first system (with appropriate reconfiguration).

Re: MMDVM needs HDMI display connected

Pi's in general don't handle voltage sags/surges very well, particularly with high demand devices like monitors, particularly with earlier models of Pi's, so indiscriminate plugging/unplugging can be disruptive. And, out of the box, Pi-Star does not come with HDMI hot-plugged. You can try adding tha...

Re: RPi 4B for MMDVM hotspot...Am I nuts?

Probably the easiest route would be to clone the drive from your working system (using Pi-Imager) and insert it into your second system, bring it up and then reconfigure it so you don't duplicate hostname and frequencies and go from there. Trying to start over from scratch is/would be more involved/...

Re: Old Zum MMDVM on a new Raspberry Pi4/B ??

Problematic?!? I have several "20-pin" hats that function exactly the same as the 40-pin hats. The center block of 20 pins are effectively "inert" - they aren't used by the circuitry on the HAT in any way. My guess is the 20 pin versions are simply a design/manufacturing decision...

Re: Incorrect time and date

Thank you for confirming my suspicions/conjectures here! But as a warning, changing the IP address isn't a permanent fix: your hotspot may "de-sync" down the road (and may go unnoticed if it happens while you're running), so you may have to repeat the "fix" again at some point. T...

Re: Incorrect time and date

Possible but doubtful. Does your external IP address change when you change routers? Do the external DNS server IP addresses change when you switch routers? Did your ISP assign/suggest those DNS addresses? Can you change them to something else (i.e. will your ISP let you do that)? But first, try thi...

Re: Old Zum MMDVM on a new Raspberry Pi4/B ??

A pi-0 form factor HAT can be used on the larger PI-2/3/4's without problems, except to note that the larger form factors do not provide support on all four corners of the HAT so care must be take to not torque the HAT too much as all it's physical support depends on its GPIO connector. You can boos...

Re: Incorrect time and date

Raspberry Pi's do not have a native, onboard clock (RTC) that maintains the time/date between power outages. It "fakes" the clock by saving the current time/date values when powered off and restoring them when you come back up. It's the job of the operating system (not Pi-Star) to resync t...
