ARRL Slow-Scan TV Experiment Planned for Amateur Radio on the International Space Station

Amateur Radio on the International Space Station (ARISS), in collaboration with ARRL The National Association for Amateur Radio®, plans to carry out a special slow-scan TV (SSTV) experiment from the ISS on Wednesday 26th July 2023. During the event, the Columbus Module Repeater, transmitting at 437.800 MHz, will carry a message to be received by teachers attending the ARRL Teachers Institute on Wireless Technology professional development class. The pass will be over the Mid-Atlantic and New England area, with transmissions scheduled to begin at 20:05 UTC (16:05 ET) and end at 20:20 UTC (16:20 ET). If necessary, a backup window is scheduled from 21:40 UTC (17:40 ET) to 21:55 UTC (17:55 ET).

Hams Honour Retired Search and Rescue Planes

/

Four aircraft used by Canada’s Air Force for S&R work were retired during the pandemic without much fanfare. Those four planes are now getting their retirement party thanks to amateurs who love aviation as much as they love ham radio. Using the antennas on board the planes (which will be grounded as museum pieces now in four provinces) they will be calling QRZ on July 22nd and will be open to attract visitors from the region and they will even attempt a 2m net between all four planes. This event is called Buffalos on the Air, so named for the RCAF’s CC115 Buffalo aircraft. It was organised mainly by aircraft technician Phil Tanner VA7XOZ, who worked on the planes.

This is a way to mark history, to educate the public about the S&R function of the planes and, of course, to show people what amateur radio can do. The antennas on the planes are indeed capable of using HF frequencies reserved for amateurs because the planes in their S&R functions often had to make contact on the civilian frequencies.

Study: Commercial Satellite Constellations EMIT RFI

According to a new study, those tiny low-earth orbit satellites in those big commercial constellations may be delivering more broadband internet access and images of the Earth below. The electronics on board SpaceX and other constellations satellites may well be generating unintended electromagnetic radiation thwarting radioastronomers' research. This word comes from the Max Planck Institute for Radio Astronomy in Germany, where researchers say they made this discovery while using the facility’s Low Frequency Array telescope.
