Subject: [VHFcontesting] Harris amp on 222
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
