Heat was my concern with the MkII model since I bought it. My MkIIG doesn't seem to get as hot and I don't remember my original 706 getting that hot either. I put heat sinks on the cover of the MkII to disperse that heat and it stays cool to the touch now. You can find the article I wrote in eHam.com and in September 2004 World Radio magazine. So now I don't worry about the heat while under the middle seat.
