[ICOM] IC-7600 Questions

[Jim Vohland]

Hard to believe that in todays world that people havent heard of the infamous ic151 no tx issues with the icom 746pro. While some people swear by them, thousands suffered the "no tx" issue. Maybe it affects the 7600, maybe not. Its enough to make me leery of most icom models.

If you are going to sell this radio - and you don't know the history -
always best to send it in to Icom service for them to check things over.

Just getting in on this, so forgive me if this has been covered
It is in the Ham Band and on a Ham Freq and not on Gen Coverage freq.?

Thanks.  Went through that procedure with no joy.  You get signal on the
LCD display during transmit but no output.  I'm going to look over the
block diagram again to see if I might have missed something.  Darned
shame because the radio looks brand new.
