[arm-allstar] Node with/without radio

[Chris Souleles]

My node is UV 82 HP, RPI3 and DMK URI. Runs on 12V. I use it at home and I take it mobile. When mobile I run through an iPhone hotspot. I have a 7 inch HDMI display and a small USB cordless keyboard that connects to the RPI3. I don’t use the display and keyboard much. If you are going to operate away from the node then antenna height becomes a consideration. Remember that UHF is line of sight. The higher your antenna the longer the line of site will be (assuming local terrain doesn’t get in the way).
