[ICOM] PW-1 What does this mean?

[jim fox]

Tony,
     I had exactly the same thing happen with my IC4-KL.. It turned out to 
be a relay failed.
I tried to find the repair sheet that Icom sent me after they repaired it, 
but no luck.. The relay either to the filter unit or combiner.. Those finals 
are very well protected. I would be supprised if it turns out to be that.. I 
sent the RF portion to Icom and they fixed it and returned it to me air 
freight and the bill was $150.. Call them first and get their ideas..  Jim /
