[WriteLog] K3 and KPA500

[Gary AL9A]

I don't run SO2R (yet :) ), but I have some questions about your setup. 
What interface are you using for the radio switching control?  Do you use 
band pass filters?  How are they switched into the correct configuration for 
the bands you are working?  I'm assuming your S&P radio is on a different 
band than the K3, but if the fault message is "PWRIN HI" it seems to me that 
too much RF may be getting through the band pass filters and into the 
receive circuits on the K3 and/or the KPA500.  What about antenna 
separation?  Does the fault occur with a particular combination of 
send/receive antennas or it doesn't seem to matter?

73,
