Long ago, when I started with PSK31, the word was - use low power. Dial the rig down (approximately 20-35) watts,adjust mic gain for ALC flicker, then back mic gain off a smidge.
But I've been out of digital mode for a year or more and my recent searches come up with, "...keep the rig at high power (75 - 85 watts) and adjust the mic gain till power meter reads 25-35 watts? It couldn't be till ALC flickers because that's a standard SSB signal at 80 watts at 100% duty cycle and I don't think that was the goal. There was something about keeping the power level high for linearity. Would I use some digital software like the old WinPSK that has a tune button. Push the tune button and adjust mic gain till forward power meter reads the 30 or so watts? What is today's "Best Practices". Thank you and 73, Paul
