[Icom] 775

[martyp]

Hello. I just got an HM-I mike for my 775-DSP and when I connect it up to 
the 775, I get a terrible ground loop. It works fine with my Goldline 
though. When I connect the HM-I to the 756Pro II, I don't seem to have any 
problem. I then removed the ground and external speaker from the 775 and 
still have the problem. Just to be fair, I took the ground off of the 
756Pro II and connected it up to the 775. I still have the same problem. I 
heard tales of some of the HM-I's having screws at the base of the mike 
being a little too long and causing it to ground out the 8v's. Anyone have 
any experience with the HM-I and the 775-DSP ? Thanks for your assistance.
