Heinz,
That buffer amp is for an IF output from the K2, and is NOT an amplifier
keying output.

Jay,
You will need to key the amplifier with a keying output from the K2.
Yes, the amp will detect band and frequency, but you still need a KEYOUT
from the K2.
The best solution is to use the N0SS Amplifier Keying board. Since Tom
is SK, no kits are available, but I understand you can obtain the boards
from FAR circuits - or the circuit is simple enough that you can build
it on perfboard using Tom's full size board layout. See
http://www.mmccs.com/mmarc/n0ss/k2_t-r_rly_drvr.pdf.
Thank you for your help at RARSfest - the Amazon package arrived today -
Thanks.

Greetings all,
How could I use the KXPA100 amp with my K2? I don't think the K2 has a
keying line, and so I wonder if the KXPA100 would automatically detect
band and frequency through the built-in tuner without a keying line
cable. Any info appreciated.
