[Elecraft] K-Pod data wiring

[Wes Stewart]

You are correct.  The worry is that a wire dangling on that pin will upset the 
controller if RF or other noise is induced.  My informant had the bright idea to 
use the existing cable to get out of the radio and dangle it somewhere to the 
rear and then use an RJ12 female-to-female connector and a longer standard RJ12 
cable to the K-Pod.  Not elegant but effective.  Parts are on order.
