The physical switch to power the unit on, apply volt ohm meter and see if the full voltage passes through the switch when keyed? The only supply with enough current on demand (minus a good automobile battery) that I have are older xbox 360 power supplies, the label reads 203 watt 15 amp 12 volt 5 volt, I havent been able to crack one open yet to see if any potentiometer exists to allow for adjustment of output voltage. They only output a12v line & 5v rail which shorts to ground to soft-power on the psu and bring it out of standby mode , I see now that I probably left excessive lengths of the original wire on the unit before attatching the radio power connector which had it's own several feet of wire to add to the original wires, In the morning i'm going to shorten the leads to a more reasonable length (short). This should stop any current bottlenecks to the radio at least.

I have been doing all my talking and rf power measurements on 12 volts for months, with a proper 13.8v I should see more output from some of my radios!

I cannot format this text very well on my mobile phone sorry, DOH i have over 6 feet of wire before the power even reaches the radio!! Huge error on my part, also these supplies say 16.5 A not 15 amps. When im rested in the morning I will begin my quest for D.C. power then it's R.F. resonating off my k40.
