web search. Not sure how it's done on the rpi5. I think on the rpi4, you have to initially boot off of microsd card and tinker with a config within raspi-config, though I am not sure

using the "dd" command, it should be possible, yes

though using an ssd/nvme seems like, from the outside looking in, may be overkill

wired or wireless?

web search shows the following, make sure you copy the sd card before upgrading, just in case

what was your solution?

Can you get the radio into monitor mode, for both time slots?

dumb and probably obvious question(s). Have you rebooted?

are you sure of the IP address?

Just looked at my config. try changing the "Nextion Field" to "ON7LDS L3"

shouldn't the TX & RX frequencies be the same?

Mine are, and it works

if you can SSH into the pi-star, try the following;

ping 4.2.2.1

it should return something like;

ping 4.2.2.1
