Stephen, Unless your K2/100 is unusual in some way or another, you do not need a separate power cable to the base K2.
One reason to connect the base K2 power to a battery and the KPA100 power to an AC powered supply is in the case that AC mains power is interrupted, you can continue a QSO at low power, only the KPA100 power drops off and you still have the QRP signal. As you have it wired right now, you should have a fuse in the wire to the base K2. That fuse protects the wire from vaporizing in case of a fault (fuse located near the battery). A battery can produce a LOT of current. 73, Don W3FPR On 10/7/2012 10:23 AM, Stephen Roberts wrote: > I have a k2/100 and have a rechargeable 13.8 battery on the low power input > and a 35A power supply for main power to the 100w amp.
