[Elecraft] K2/100

[Bruce Beford]

You are correct, John.
The K2/100 can’t also have the KAT2 antenna tuner installed at the same time. The lid that has the 100W amplifier occupies the space that the KAT2 QRP tuner would be in.

Sometimes, an owner will keep the original cover and speaker with the KAT2 attached, to swap out the KPA100 lid. The description and pictures in this listing do not show that.
Thanks,

Bruce Beford
