Has anyone tweaked a channel 11 amp for 222 mhz?  I am using 2 modules in parallel. With 30 watts drive I am seeing 18 amps at 50 volts input. That would be 900 watts input. I am getting 400 out. Not very efficient. It makes a little more at 220 than 222. Thanks Mike _______________________________________________
