[Elecraft] K2 with KPA-100

[Don Wilhelm]

Brian,

Even though the KAT2 and the KPA100 are present in the "Twins" 
configuration, when the K2 MCU detects the presence of the KPA100, the 
KAT2 is bypassed and set to connect only to ANT1.
In other words, the KAT2 will not work with the KPA100 present.

If an ATU is required with the KPA100 in-line, the KAT100  or other ATU 
between the KPA100 output and the antenna is necessary.

Yes, the KAT2 is rated at up to 20 watts.  The KAT100 is rated at up to 
about 150 watts.

73,
Don W3FPR
