The slide presentation use at the ARRL Boxboro, MA Convention is now available via the ARUFON,org web site (the Amateur Radio UFO Net) at: www.arufon.org
Enjoyed the presentation very much. Checked into their weekly net at 6pm central time zone on 3845 KHz Sunday evening for the first time and enjoyed it very much. Good group of very knowledgeable hams in the net.
