Bill, Your Q is logical, but nothing was in common on all occasions, other than sitting inside the same cockpit: I tried transmitting with the ICOM inside the cockpit only one time (it was NOT attached to antenna or PTT or power or the airplane in any way). And the salesman said afterward, as have some others on this list "ICOM HAS TO be connected to airplane antenna to transmit adequately." So it, at least, was apparently performing to spec (although I've sent a Q to the mfgr., too, just to be sure). Tomorrow, I'll try connecting the ICOM to the airplane antenna. I did wear the same Mach 1 headset with both radios that day. But my original loss of transmission with the built-in radio was on a day when I was wearing a Telex-Echelon headset, so it's not the headset. The sounds also haven't been acting like it was the headset. The tower controller said it sounded to him very vibration-related. So, we should know more tomorrow, based upon (1) whether I can get the ICOM working connected to the plane antenna, (2) whether I find corrosion or anything broken when I open up the back and get to the antenna base, (3) or when the Spruce radio shop in Chino looks at it all, if I can get them to look.

What is common to both useages? Using the same headset? Using the same intercom? Using an external PTT?

Linda, I think your ICOM should sound crystal clear and work fine for a distance of a couple or five miles with the rubber ducky. Range after that gets problematic because of the tiny radiator length of the antenna. I have talked as far as 7-10 miles with mine, using the rubber ducky antenna in good conditions. It should certainly work fine at traffic pattern distances. If youre not getting good communications with it standing on the ramp beside your plane, then either the rubber ducky antenna is bad (that happens) or the radio has problems. This is worth resolving so youll have a reliable backup.
