[1000mp] Power supply Prob?

[Jim Hill]

Thanks for all the helpful replies.  They were helpful in eliminating 
possible causes.
I took the radio and power supply to WB6TMH, a good technician, and we 
determined that the problem is indeed the power supply.  After a couple 
of hours of testing, we can only come up with the conclusion that the 
problem is a module the does the switching.  Unfortunately, its a 
custom unit, so I am in the process of seeing if I can get one from 
Yaesu.
If anyone has any trouble shooting tips for the power supply, I would 
appreciate them.
Thanks again,
Jim, K6UUW
