That's your problem, not Elecraft's. The KX3 was specifically designed 
as a backpacking radio that could also do other things. AFAIK, neither 
Wayne nor Eric is a JT65 op or a VHF op, so they didn't think of the 
thermal issue until users brought it up. When they did, Elecraft 
developed the temperature compensation as a solution and also improved 
the heat sink. I did both to my KX3. It took about three hours, half of 
which was reading the instructions and cooling the radio for the second 
part of the procedure.

Reading ARRL Lab test reports clearly shows that Your "trusty old FT817" 
isn't one-tenth the radio that the KX3 is. The KX3 is FAR cleaner on TX 
and FAR superior on RX. But the KX3 is fundamentally an HF + 6M radio, 
not a 2M radio. A few weeks ago, we used a KX3 with the KXPA100 and PX3 
for a very successful mobile run in the 7th Area QSO Party.  Slide #8 in 
k9yc.com/7QP.pdf shows the setup that W6GJB put together. W6GJB drove 
while W6JTI operated, riding shotgun. The KXPA100 is on the floor of the 
back seat.
