The complaint was not "ridiculous". The original observation was....The K3 distorts and the FT-817 doesn't under the same conditions.
The poor guy was called stupid, ridiculous, ignorant and told he needs to "study" and go back to school. I think he has a good question and I have yet to see a logical answer. Claims that the K3 is "souped up" and exempt from strong signal overload is the ridiculous part! If the K3 distorts on 109DB signals and the FT-817 doesn't then so be it. It's a weakness. Just leave it at that. I'm sure the 817 has plenty more weaknesses! Let's not let this list get like the TenTec reflector. Mention something negative there and you are immediately put down or soon thrown off. I've recently subscribed to the IC-7600 Yahoo group just to watch how the new radio was doing. So far I've seen two concerns. Some have a dimmer screen saver than others and a few have had to do a master reset because of audio drop out and it's starting to look like a glitch in some 3rd party rig control program causing that. Otherwise, everyone seems satisfied. Of course, those guys know that ICOM isn't going to respond to anything that's said so maybe they just don't bother. I'm still enjoying my K3. Things have been rather lopsided lately however. I am able to copy cw through the QRN better than the other guy, especially when I take advantage of the NR. This gives me er...maybe 6db advantage or so. Therefore I've ordered an ALS-600 to help make up the difference. The K3's superior receiver is costing me money!
