I would have thought that the heating is a result of inefficiency. The heat is 
lower at QRP levels than at higher power levels since there is less power to 
produce heat. If a balun is converting 10% of energy into heat, then more 
heat is produced with 100 watts than 5 watts, but the loss is still the same 
10%. Am I wrong?
