Thanks again guys and thanks Bob for the numbers. I wasn't making notes when tracking drive vs. output power - just a fairly gross report of what I was seeing. The entire reason for my question is my Acom 1000 amp (4CX800) would need about 55 watts drive to produce ~950 watts, I was very surprised the KPA1500 needed so little drive power.
That Acom 1000 was a very good amp and practically idiot proof which I needed with wire antennas, now I have a DB18E and a 75M inverted V dipole so we're always under 2:1. (The Acom was sold 45 minutes after I listed it on QRZ!)
