KC4AAA 2001 Antarctica

Amundsen-Scott South Pole Station

The operator was Franklin E "Skip" Withrow III, WB0BBE.
The following is from Skip, WB0BBE:
I did three summers at South Pole (93/94, 97/98/, 01/02) and 8 weeks at Palmer Station (KC4AAC) as a communications technician.
The military was pretty much out of Antarctica by that point except for air ops.
I worked for the support contractor to the National Science Foundation.
My duties included repair and maintenance of all the communications systems from the telephone system, HF, VHF, and UHF radio systems, and microwave satellite systems.
I was involved with the first real-time internet connection to South Pole in 93/94 (via GOES 2/3) and assembled the Intelsat ground station at Palmer (2002).   
I did lots of operating from KC4AAA, a fair bit from KC4AAC, and even some from KC4USV when transiting through McMurdo.
