I have one of Mark’s micro-node’s to connect to Allstar and have a node number through Allmon, (490470.) Recently, I purchased a raspberry pi4 and want to create another node, (490471,) to do simplex on 220 around our neck of the woods. I have no real technical/programming prowess, (heck I am an old man that uses a MacBook!), so I am looking for a step by step instruction manual on exactly what to do now. I am able enough to snap together the Pi4, so I have that going for me, but the next step of imaging the software on a blank card, etc is the next step. The first question I would have is…does the micro card need to have a program installed such as linux, etc, before doing anything else first?

Thanks in advance for all the help. I recently became aware of the app_rpt versus HamVoip kerfuffle and wish to stick with the original for some of the obvious reasons.
