I am thinking about using one of my mobile radios indoors. Would one of those Amazon/ ebay regulated 12vdc 50A 600W PSU work? Like a 50A version of this perhaps? I think I'll enjoy the experience more than being in the truck. Url wouldn't link, sorry. Item description; PowerMax PM3-55 110 V to 12 V DC Power Supply Converter Charger for Rv Pm3-55, 55Amp 13.2 Vdc range 13.6 Vdc range 14.4 Vdc range Ul and cul approved Reverse battery protection The radio in question is an RCI2970N4, 40A according to the user manual. I guess all that ( lol ) is needed next is a home made dipole antenna somewhere discreet and up hign .
