I own two X9303 2.4 radios. The one I purchased in late 2007 has the problem and the other one, purchased in Feb 08 does not have any sign of chafing at all. The older one has quite a bit more use, but even so, I think the newer one should be showing wear if it was not clearing the regulator chip. However, there's nothing to indicate that over time the wiring may not creep out of position and start wearing. This demands a really close look by Horizon to come up with a permanent remedy. Check the picture of the voltage regulator chip on the RF board. There is visible wear on one edge of the chip and the epoxy powder residue (from the regulator case), mixed with some copper from the wire is visible on the circuit board.

Thanks for reporting this Bob, I'm sure you saved me from a crash in the future!
