[Elecraft] two transceivers and one antenna

[Joe Subich, W4TV]

Although it's a bit on the wimpy side, MFJ makes an "RF Safety Switch" 
that does just this.  See: 
 <http://www.mfjenterprises.com/Product.php?productid=MFJ-1703> 

It is also possible to build your own - of much higher quality - 
by using a pair of Top Ten Devices A/BSS relays and some T 
connectors.
