Shortwave Radio Recordings: Ham radio contacts between W2PVF (SK) and two Antarctic Stations, circa 1974

Many thanks to Bill Hemphill (WD9EQD) who is one of our newest contributors at the Shortwave Radio Audio Archive (SRAA). Bill approached me at the Winter SWL Fest this year noting that he has a wide variety of radio-related audio recordings to share with the SRAA and the SWLing Post.

This week, Bill shared two fascinating tape recordings he originally acquired from an estate sale box.  These recordings were originally made in 1974 by the late Jim Hayward (W2PVF) in Absecon, New Jersey (USA) with two different ham radio stations in Antarctica.

This first recording is between W2PVF and KC4AAC of Palmer Station. The audio starts mid conversation:

The second recording is between W2PVF and LU1ZE of the Argentine Antarctica Station. The operator at the microphone is W1PV. The recording even includes a phone patch:

Bill, thanks so much for sharing these recordings–I thoroughly enjoyed them!

I’m so impressed with the audio and signal quality of the Antarctic stations.  In 1974, we were approaching a solar minimum in Solar Cycle 20. Still, I bet conditions were better than anything we’ve seen in over a decade!

I’m curious if any Post readers have ever made contact with either of these stations or even know the operators in the recordings? Bill notes that  Jim (W2PVF) was president of the local Atlantic City Electric Company for many years. Would be fun to share these recordings with the some of the original operators, if they’re around!

Work the World with WSJT-X

Video of the talk given by Professor Joe Taylor K1JT about the FT-8 and WSPR modes at the 2018 MicroHAMS Digital Conference on March 24

Budd Churchward WB7FHC writes:

Dr. Joe Taylor, K1JT, author of many of the weak signal digital modes and co-author of the very popular FT-8 mode presented: “Work the World with WSJT-X”  at the 2018 MicroHAMS Digital Conference in Redmond, Washington about the WSJT-X Digital Software Suite for Amatuer Radio.

Dr. Taylor gives a detailed description of both the FT-8 and WSPR modes that so may Hams are using all over the world.

Wired: Hunting Radiosondes

SOME RETIREES TAKE up fly fishing. Others pick up golf. But when Roland—or “F5ZV,” as he’s known on ham radio—left his job in Belfort, France a decade ago, he devoted his newfound leisure to a far more peculiar hobby: hunting radiosondes.

The white plastic boxes contain instruments to measure things like wind, temperature and humidity; meteorologists send them skywards on balloons, and they transmit data back over radio waves. But somewhere around 100,000 feet, the balloons burst, and the radiosondes parachute back to earth.

Roland began using a radio receiver and antenna to track them to the rooftops, parking lots, and random cow pastures where they land. “He was completely obsessed with radiosondes,” says Swiss photographer Vincent Levrat, who documents the chase in his quirky series Catch Me If You Can. “He would wake up at night just to hunt.”

By Roland’s own estimation, there are hundreds of other radiosonde hunters across Europe who monitor launch schedules for weather station balloons. They begin each hunt by using software called Balloon Track to predict the general area where a radiosonde might land; Balloon Track calculates the trajectory based on wind speed and burst altitude.[…]
