HAM RADIO IN SPACE: ISS RANDOM CONTACTS BACK

After a seemingly long period when the astronaut and cosmonaut hams on
board the International Space Station seemed only to be making pre-
planned contacts with schools, random contacts are back. For several
days last week, Colonel Doug Wheelock, KF5BOC, took to the air from the
orbital outpost to talk to hams around the globe. Here's a time
compressed sample as supplied to us by Scott Avery, WA6LIE:

That recording was made on July 11th. Among the other stations
Wheelock is known to have worked are since activating ISS station NA1SS
were KD5DCB and PD0RKC to name only a few. (ARNewslineT with audio
