[Elecraft] Cable

[Dave Van Wallaghen]

Hi Harold,

You will connect the K2 to the KXPA100 as you would any 3rd party 
transceiver setup as described in the KXPA100 manual. You will just 
route RF from the K2 to the KXPA100 input and provide a keying line from 
the K2 to the keying input of the KXPA100. This means you will need to 
add the capability of providing a keying output to the K2 as it is not 
available natively. If you happen to have an older K2 with the K60XV 
module installed, you can pick off the proper keying signal from that 
module. Otherwise, you will need a circuit to proved the keying signal. 
There are a number of circuits out there on the web that show how to do 
this. I happen to sell a kit for the K2 that was designed by Tom 
Hammond, N0SS (SK) to do exactly this: 
https://www.w8fgu.com/k2_trdriver.html. It mounts where the K60XV module 
would reside in the K2.

With all of this said, you will not have a really tight integration with 
the KXPA100 as you would the obsolete KPA100. But it works very well. 
Band changes will be manual, but RF sensing in the KXPA100 would provide 
automatic band changing with just a dit of RF from the K2.

Hope this helps. If you have further questions or need support for your 
K2, I am also the K2 support guy for Elecraft as well. My predecessor 
Don Wilhelm, W3FPR is usually monitoring this list and provides 
excellent support for all things Elecraft where he can.

73,
Dave, W8FGU
