[Elecraft] Cute audio switch for dual K3s and a computer

[Joe Subich, W4TV]

Similar switches are available from many sources.  In the US, 
try www.radioshack.com/product/index.jsp?productId=2049645# 
which should be available in most stores for $21.99. 

Radio Shack also lists the Sima switch for < $30 on-line 
but it is currently out of stock.
