This is in the most recent ARRL contesting newsletter; the author of the project page is our own K5LXP.  Very impressive work, and a great project, IMO:

The interlocking to prevent two rigs connecting to the same antenna is very clever.

I agree with the last statement the author made.  If he didn't already have most of the parts in hand it would have been wiser $$$ wise to buy the Array Solutions 6-Pack.  It has all the same features. 

I own a 6-pack and I am very happy with the quality and operation using it in two separate radio rooms.  I have no connection monetary or otherwise with Array Solutions, just a happy customer.

Well written and presented article Cecil - good job!  AND a lot of thinking went into that switch also.

Cheaper to buy rather than build is true lots of times, but it's so much more fun to build..... and I learn by building also.  AND you do usually have to pay for an education:)

I have the circuit boards on hand.  $15 US dollars each plus shipping.  You can find many relays cheap (6, 12, 24 volt) that will work on Ebay.  I mounted the relays directly to the pc board and did not use sockets.  Payment via Paypal at "unosuave@hotmail.com".
