This may be old news, but I wanted to see if my IC-7300 had the key-up power spike that's been reported on other Icom rigs when the power output is turned down. The short answer is that I don't see any sign of overshoot, so this rig should be safe to use with amplifiers or transverters that want the wick turned down. (Of course, you can still blow things up by forgetting to turn the power down...) Details and pretty screenshots at https://blog.febo.com/?p=321 73, John

Well, the detriment of that initial spike, from my experience, is that the spike will trigger a false shut-down of a micro-controlled power amplifier.
