Hi again, yall!
So I'm doing a little horse trading with the Magnum S3 that has issues, and in the process I've acquired an S380. Very solid radio, only thing holding it back I think is the coax/antennas(cophased coaxes factory installed by Kenworth, dual 4' Francis antennas), and possibly bigger power supply cable.
I say power supply cable because I'm running one from a Cobra 29 Classic, meant for a 4W output radio. I could swing 100 if I wanted, so that has to be a weak link, right? I have a Magnum noise filtering cable for it with bigger wires and a 10-amp fuse. My concern is that 10 amps might still be starving the radio, since there's always a lot more wattage going into one than being put out from it. Assuming power = voltage x current, 14.4V x 10A = 144W. For some reason that sounds a bit too low.
Would I benefit at all from running say, a 15A fuse at the truck's panel(has a dedicated CB circuit on it), and then straight-wire the filter/power cable to it? Or should I stick with 10A?
