I agree. Back in the old days, when we men were boys and receivers glowed orange, we tended to set audio gain constant and vary the RF gain. Many very good operators still do. Indeed, some also turn off AGC. The most critical thing is to make sure that nothing is getting overdriven in either the analog or digital domain. I've seen distortion in the output stages of "good" computer sound cards increase by 10 dB in the 6 dB range below clip, which is the reason for my advice to run them 6-10 dB below clip when feeding a radio. And it's also well known that A/D converters errors increase with signals near the noise level, which is the reason better sound cards can provide better decoding of weaker signals. 73, Jim K9YC ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
