[ICOM] IC-756PROIII No Transmit ESD Failures

[Alan Zack]

Possible. I use a anti static work pad on the desk where my hand rests 
that is grounded which I would hope would prevent it. It is the same ESD 
work pad that you would use at a work bench doing repairs.

Burghardt stated to me that they have installed 400 of their mods to 
756's to prevent this from happening with no failures after the mod. 
This seems like a large number but here is the direct quote from their 
email to me. Makes you wonder why Burghardt found the problem and fixed 
it when Icom denies any problem exists.

Sorry to hear of your trouble with the IC-756PRO3.   We do have a module 
which we have produced called the BEV-756 ($79.95 plus labor) which does 
protect against that exact problem.   It is very effective as we have 
had no failures after the install of over 400 modules. Approximate labor 
for repair and install would be $187.50.
