ARLS003 Operators/Monitors Wanted for Meteor Scatter QSO Party
December 12-13
HamSCI – the Ham Radio Citizen Science Investigation program – is looking for “ping jockeys,” or ham radio operators who enjoy making contacts via meteor scatter (MS), to take part in its Meteor Scatter QSO Party during the Geminids meteor shower on December 12 and 13, 2025. Operation will take place on the 10-meter and 6-meter bands only (28.145 and 50.260 MHz), using the MSK144 digital protocol. The event is a combination on-air contest and data collection for what HamSCI describes as an experiment “to analyze the feasibility of HF meteor scatter for future scientific research.”
HamSCI pointed out that little research has been done on 10-meter meteor scatter, due to past symbol rate limits imposed by the FCC. Those limits were removed in early 2024.
The group is looking for both active operators (seeking and making contacts) and passive monitors, recording .WAV files of MS contacts and uploading them to PSK Reporter. Researchers will collect contact data from both 10 and 6 meters and will analyze that data offline, using PSK Reporter raw data, operator contact logs, and .WAV files.
HamSCI says the best operating times will be between 8 PM and 8 AM local time, and suggests announcing CQs on “Ping Jockey Central” (https://www.pingjockey.net/cgi-bin/pingtalk – especially for 10 meters) and the groups.io page (https://groups.io/g/FrontRange6Meter/topics) of the Front Range Six Meter Group (especially for 6 meters).
