Randy,
Since you will be using the K2 with the KPA100, you need to strongly
consider adding to the list of upgrade mods shown on the K2 A to B
instruction sheet the K2 Keying Waveshape mod. It is important to keep
the keyclicks down. They are not obvious with the 10 watt K2, but rear
their ugly heads when the KPA100 is in-line.
Elecraft no longer supplies the kit of parts, because the PIN diode
specified is no longer available. However, there is a "fix for that"
and it is included with each and every new K2 kit.
I will be sending you the original Keying Waveshape Mod instructions by
private email, along with the Elecraft part to replace the PIN diode
specified.
73,
Don W3FPR

Thanks to all for your well considered replies, both on and off line. I had
pretty much decided to do the Rev A/B mod to my K2 and keep it for QRP and the
5th Wheel and purchase the 7300 for the base station.
Then, one of our members offered a KPA-100/KAT-100 in an EC-2 enclosure at a
very reasonable price. After much consideration, I’ve decided to upgrade the K2
and purchase the EC-2 unit. Just seems to work best for my situation and chosen
modes.
Thanks once again to all for being a great sounding board!
