Hey guys, FINALLY, I got the 4-1000A PA up and working! Yes, I've been on the air with it all night tonight and it performs GREAT. I am getting an EASY 1.5KW from about 80 W of drive on 20M and on 10

Hi Jon... Congratulations! But I suspect you can squeeze another 5-10% efficiency out of it with more work. I mean, we're never satisfied, are we? I didn't participate in earlier discussions of gg ef

Efficiency is very hard to measure accurately, and the potential errors mean that he might already have another 5-10% in fact... or it might be 5-10% worse. Typically Ep errors could be 2% full-scale

? Indeed, Ian, and RF wattmeters must operate into 50 +/- j0 ohm load in order to read semi-accurately. . . [An ordinary DMM is a reliable means of checking to see if the 50 ohms DC component is the

Correct. I've not a real good way to measure plate voltage. I have a 30KV probe, but that only gets me in the ballpark of a KV or so. After I got the amp up and running, I realized that the meter in

I agree. For most of us, efficiency is only a broad-brush indicator that everything else is working OK. Enjoy! 73 from Ian G3SEK Editor, 'The VHF/UHF DX Book' 'In Practice' columnist for RadCom (RSGB
