I have a weird one on the bench, when I have had IC7000's with no output on any band it has always been an input/output feed or driver board issue.
The unit I am working on has RF into the driver board and DC Bias, Supply rail on the output side but almost no RF out so i thought, driver board dead, easy fix......but no....
I removed the board and it looks like new, the board tests ok on a component tester, Per Icom's advice I have reset the CPU.
My next step is to replace the driver board in case something funky is going on with it, what do the Guru's here think of a diagnostic step may have missed.
Thanks, any help is always appreciated.
