[ICOM] IC-7600 Questions

[Rick Markey, KN3C]

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.
