Many IC-7300 owners struggle with aggressive ALC behavior that reduces average power output compared to other transceivers. The key insight is that proper ALC setting should peak around 1/4 to 1/2 maximum, never more - shoot for maxing at 1/4 with occasional peaks hitting 1/3.
Unlike older rigs where any ALC indication was bad, the IC-7300 manual states to "adjust the device's output level to be within the ALC zone" for SSB data modes. This SDR architecture requires different operating techniques than traditional analog transceivers.
For consistent results: disable compressor temporarily, use Menu > Meter to monitor ALC while speaking normally, and adjust mic gain to stay within the 1/4 range. Pushing ALC too hard makes it overly aggressive and actually cuts average power.
