Hi Steve (N8TFD),

I have two IC-2720 rigs with the HM-133 mic and I don't have a problem at 
all.
In fact I was going to ask is the HM-133 will work with the IC-706MKIIG.
I don't care for the HM-103 that is supplied with the IC-706MKIIG.
Has  anyone ever used the HM-133 mic with the IC-706MKIIG?

73 and Thanks,
Jim, K4TXJ
Louisville, Ky.
