I had experienced loss of communication ,imediately after take-off, with all gen correctly functioning, on all 3 VHF radios. The stuck mike is out of the question , we checked and removed all mikes,use both cpt and fo buttons on different radios and freq , nothing.
The problem disapeared after around 5 min, and at home base the tech's couldn't find anything wrong.The problem did not reapeared on that plane.
So,Glueball,anything can and will happen, someday.
