The rig has the following requirements: DC 10-14 v , 15 max. 360mA rec, current max 3A-3.7 A. Can I use a jell storage battery from tractor supply? Can I use my 12 v power supply I have for my Alinco HF when I want to operate from my back porch or is it better to stay with battery power . Sorry if these are dumb questions but this is new to me and I dont want to make any stupid moves and damage my new rig. Any help appreciated.
