[Icom] Quick question...is there a Pro/Pro II reflector?

Tue, 26 Mar 2002 20:56:13 -0500

Dave you know the thing that kills me....this should not have to be beaten
to death. Icom should have correct specs listed instead of changing them or
giving folks the run around when asking for them. This should also not be an
issue for a radio that cost as much as the Pro II does. I thought they had
this taken care of. The bottom line I have found is there are still way too
many people having relay problem failures and that is well documented and
even the Tec's at AES supply told me so today and then there are some that
have had no problems...go figure. No offense, but I agree with you but again
we shouldn't have to be having this problem or discussion if Icom would
build the thing right to start with or at least come clean about the specs
on their radios and Kenwood and Yaesu are no different. Thanks for your
objective input but I guess I better try and find an external relay hi hi
LOL. Steve
