[Elecraft] Power for KAT100

Thu Jul 24 22:04:01 2003

Tom, et al:

Series diode D10 in the K2 is there to protect against someone (like me) 
from connecting his 35A 12VDC power supply to the K2, BUT with the polarity 
reversed... without D10, as a friend always reminds me, "Bad things will 
happen".

A couple fella suggested adding one (or more) 'taps' off of the power 
connector which plugs into the KPA100. That's what I've done... one heavy 
(#12) wire and a couple #12 wires, all going to appropriate connectors.
