Henry Brown, K1WCC, posts on Facebook:K1WCC operating as W1AA at the Marconi Transmitter Building in Marion, MA on April 23rd for International Marconi Day.
I was able to make 100 QSOs on 40 and 20 meters in short order, using 100 watts and portable antennas.
A great operating location, no audible or RF noise issues and a big thank you to Frank, the owner of the building, who kindly allowed me to use the parking area for my operation.
