An alternate method of blowing up the bias board it to put exciter power 
to the 425 with no load on the output, even with the 425 in standby or 
not even powered up. The easiest way to do this is to use a separate 
receive antenna on your Omni VI, so that when your transmit antenna 
switch is set to an unused port, you don't notice right away, because 
the receiver sounds fine. With no load on the output of the 425, there 
is nowhere for the exciter power to go except the small parts on the 
bias board. I know this works, I have tried it.
