[ICOM] Low Output - IC746

[Mike]

Hello,

I have an IC746 with low, 10 W maximum, output.  Need ideas on where 
to look for the problem.

Circumstances are:
Radio was working okay two days ago.  The antennas and all the 
control cables to the shack were disconnected due to thunderstorms in 
the area during the two days.  This morning everything was 
reconnected when the lack of output was found.  The receiver works 
fine though.

The voltage to the radio is a solid 13.5 V receive or transmit.

The other IC746 in the SO2R set-up works fine both in its normal SO2R 
location and when substituted for the low output 746.  Likewise the 
low output 746 still has a low output when in the other radio's SO2R 
location.

The low output 746 has Ant. 1 selected and the ant. is connected to 
the Ant. 1 connector.

I haven't look in the archives or on any of the other Icom lists yet.

Again, any ideas on where to look for the problem causing the low output?

         73,
         Mike, K4GMH
