On the last weekend of May, the Hungarian Radio Amateur Society MARSZ will be on the air in Budapest's City Park for the "Children's Day Event" as HG5RUG on 40m, around 7.095 .
The IARU Region-1 Monitoring System has published its report for April. It reports a marked increase of intrusions to our allocations, mainly due to the war in Ukraine, detailing the signal types and the affected frequencies. One can find the report under the heading "Spectrum" on www.iaru-r1.org .
Two military satellites recently exchanged more than 200 gigabits of data over a distance of about 100 kilometers using laser communication in space. Satellites generally do not communicate directly with each other. Instead, they use radio signals to transfer data down to a ground station on Earth, which then relays this data to another satellite. Optical terminals between satellites are considered to be faster and more secure. The two satellites, named Able and Baker, were launched last summer by the U.S. Defense Advanced Research Projects Agency as part of its Blackjack project.
A much slower data transfer takes place under more challenging conditions when communicating with humanity's outpost beyond our solar system. NASA engineers are investigating anomalous telemetry data produced by the venerable space probe Voyager 1. They are now trying to debug the probe, a formidable task as data flows from Voyager at 160 bits per second, and signals take 20 hours and 33 minutes to reach the probe. A Wednesday announcment states that the probe is operating normally, receiving and executing commands from Earth, and still doing science and phoning home with data. But Voyager 1’s attitude articulation and control system (AACS), that helps point the probe’s antenna towards Earth, does not currently reflect what’s actually happening onboard. NASA says the AACS data may appear to be randomly generated, or does not reflect any possible state the AACS could be in. The good news is that the craft is still doing fine. It’s not needed to enter safe mode and its signal is still strong, so it appears the main antenna is properly aligned even if system data suggests otherwise.
In their latest weekly news bulletin AMSAT announced the publication of a detailed paper which describes the reception of the Tianwen-1 Chinese Mars mission carried out by AMSAT-DL using the 20 meter dish at Bochum Observatory in Germany. A real-time GNU Radio decoder has been used to receive and store telemetry almost every day over the course of 10 months. Some of the telemetry variables, such as the trajectory information, have been successfully interpreted and used to track the progress of the mission. A PDF of the report is available for download at www.amsat.org .
A steep increase of active regions on both hemispheres with over 170 spots on the Earth-facing side of the Sun has raised the Solar flux to over 160 units, the Solar wind is currently at around 450km/s. Last week several strong flares caused repeated radio blackouts and a high attenuation on all bands due to a pronounced D-layer. For next week low solar activity is expected, with a kP of 2 to 3, but a high probability of M-class flares, causing few minor to moderate radio blackouts and only a slight chance for X-class flares. Expect an increase in Sporadic-E and Tropo for the higher bands, listen for signals on 10m from Asia, VK and ZL during early morning openings.
That is the news for this week. Items for inclusion in next week's radio news can be submitted by email to newsteam /at/ irts.ie for automatic forwarding to both the radio and printed news services. The deadline is midnight on Friday.
