John Reilly - N0TA and John Bredehoft - K0FTC operated a Field Day site from Squaw Mountain Lookout Tower at 11,486', just west of Denver using Special Event Callsign W0C.  (Also a SOTA activation by K0FTC.)  The tower was rented for Friday afternoon through Sunday.  Over 500 QRP CW QSOs were made in a little over 20 hours.  A 20 meter vertical and an inverted V multiband dipole were used.  A large car battery was used to power an Elad Duo transceiver with SW2 radio control software and N1MM for logging.  Several visitors that had made the hike up the mountain had the opportunity to hear about the event, CW, and amateur radio.  We had a great time and thanks to all that we exchanged QSO information.  73, John K0FTC
