07/28/2008 | K7RST For the 2nd year in a row, the Radio Society of Tucson (RST Club) operated from approximately 9200ft atop Mt. Lemmon near Tucson, Arizona. We were a 8A operation plus a VERY SUCCESSFUL GOTA station under the callsign of KD7SPY. We have well over 150 visitors to the Field Day site! It was the best Field Day I can ever recall. Temps were in the 70's while down below in the desert of Tucson, it was well over 100. -- KF0X
