HamSCI Meteor Scatter QSO Party 11-12 August 2025

Call for Operators and Monitors

HamSCI – The Ham Radio Science Citizen Investigation is preparing for a series of upcoming meteor scatter (MS) experiments. Operating will take place during two well known meteor showers: 11-12 August 2025, 0000 to 2400 UTC, for 48 hours (Perseids) and again on 12-13th December 2025 (Geminids).

This is a combination 'special event' and a contest to generate contact data during meteor scatter events using 10 meters and 6 meters.
Contest rules can be found at http://www.hamsci.org/msqp.

Ten meters has not been used much for meteor scatter study due to past symbol rate limits. But with recent changes in FCC rules, WSJT-X/MSK144 can now be used on HF bands. The HamSCI meteor scatter event will collect contact data from both 10 meters and 6 meters as part of the scheduled events in August and December. Data will be analyzed offline, comparing data from both bands, using both PSK Reporter raw data and operator contact logs from WSJT-X. User data including both logged contact and received reports are necessary for valid experimental analysis. The latter can be provided by any receive system reporting on MSK144 through PSK Reporter.

International Lighthouse Lightship Weekend

August seems to have become the international weekend for lighthouses. Countries all over the world have become involved in one for or another of lighthouse activity. Some years ago the United States Congress declared 7th August as their National Lighthouse Day and during that first week in August amateur radio operators in America set up portable stations at lighthouses and endeavour to make contact with each other. This event is known as the US National Lighthouse Week.

In Britain the Association of Lighthouse Keepers, ALK, conducts International Lighthouse Heritage Weekend on the same weekend as the ILLW in August. Their objective is to encourage Lighthouse managers, keepers and owners to open their lighthouse or lightstation and related visitors centres to the public with a view to raising the profile of lighthouses, lightvessels and other navigational aids, and preserving our maritime heritage.
