Re: [TenTec] Orion II Freqency response graph

["Ron Castro" <ronc@sonic.net>]

The standard methodology is to use a fixed output, in this case 20 Watts at 
1 kHz, then adjust the attenuator on the signal generator to maintain the 20 
Watt output.
For AM, I used a Spectrum Analyzer and watched the amplitude of the 
sidebands at 50% modulation.
