[Elecraft] Older K3/100s can be updated to avoid possible ERR 12V problem

Early K3s had tin plating on the connectors that supply 12 V DC to the KPAIO3 and KPA3 modules. We discovered that in some climates the tin plating can eventually corrode, reducing voltage to the PA module, especially when operated at high duty cycle. This can result in an ERR 12V warning
