During the past field day a number of us worked W1AW/3 28A MDC. Bill and I were speculating on how they could do that. Here is a link to more information on that station which is supported by multiple clubs and normally operates as W3AO. Note that they operated as 50A and 51A in the past. http://www.arvideonews.com/lbfd/index.html Tony W2HWW
