Just got my new KAT/KPA500 on the August Special. I have both units all wired, tested and ready to go except for the 12 to 15 VDC power connection for the KAT500. What are you experienced KAT/KPA owners using for this power source? What amperage is required? Advice would be appreciated, please. Sid. NZ7M Sent From Sid Frissell's iPad
