[Icom] 775-DSP

[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.=20
