Well, let's see if I can do this right: 15 db = 10 log (Pout / 12 watts) where 15db is the FCC maximum allowed gain. Assuming that 12 watts will drive the KPA500, we solve for Pout as: 12 watts * 10^1.5 = 379 watts
So, if I did the calculation correctly, that would be legal maximum. I would suspect the gain to be less, perhaps in the 200-300 watt range for no other reason than it feels right to my mind. There may also have been an email from Lyle that mentioned something in the 200 watt range, but I'm not sure. 73, Byron N6NUL On Thu, Dec 16, 2010 at 4:11 PM, William H.
