Hi, I have not done an extensive search as yet, but curious to see if anyone has built or bought an amplifier for the WSPR desktop . Ideally an adjustable amp from 400 milliwatts to 900 milliwatts. Flip a rotary switch enabling the user to select the designated sub 1 watt output levels. I know the guys at have been building chip amps for stereo gear / headphone gear...wondering if anyone has done anything with these chip amps (but doesn't have to be a chip amp) for the WSPR transmitters. Thanks. -stu
