Query: Voltage Drops unacceptably @ 3 amps

I purchased this to use with a 25W ham radio transceiver. At first it appeared OK but when I spoke into the mic the light on the radio would dim slightly. I made one contact who said that my audio was terrible and another said it was all noise and not intelligible. I hooked up my multimeter to test the output of the supply. During receive it was a good 13.76 VDC. But on TX with it dropped to 10.8 VDC. I checked the current being drawn and it was 3.2 amps (on TX) - well within the supposed capability of the supply. When I would talk into the mic the the voltage would drop causing distortion. To say that this can do 12V @ 5 amperes is a lie. The voltage drops down way before it gets near 5A. I'd return it but I threw the box out. 12V paperweight maybe?
