You answered your own question : "So it appears that this radio, which is a GE Mastr II mobile, doesn't like to run at the lower wattage of 10 to 20 watts out."
110w radio will not be stable at 10-20w. If you look at your output on a spectrum you probably have spurs all over the place. Any reason you cannot run it at least 1/2-2/3 power?
