Questions and answers
I have owned a IC-718 for 2 -1/2 years, I use it on CW and Digital modes often at full power and it has performed faithfully. My question is this: Is it normal to have never observed the cooling fan turn on.... not even once? No heating odors... etc. I know I should not be complaining. Any thoughts?
