I don't know if I would call it 'squeaky' but it does get pretty close to 
that description...

Hey, I was just reading my warranty info, and it says that TT will ship me 
out a replacement board so I don't have to ship the whole unit back.. Do 
they really do this? It is so nice to have a US company to deal with, I can 
only imagine what my sales rep would have said about my YAESU if I had 
asked for the same consideration....
