No, the problem is definitely with the transceivers themselves.

However, if you were using your amplifiers at the 400W level, the 
transceiver output power would have been only about 20-25W. That might 
have helped to reduce the levels of key clicks, though it wouldn't have 
been directly due to the reduction in power - more likely the effect it 
might have had on the ALC dynamics.

Nobody has really got to the bottom of why it happens... least of all 
Yaesu.
