I'm a SARA member and also Public Information Officer for HamSCI. Below is a 

copy of a release for our upcoming meteor scatter QSO party in December that 

I hope the membership will find important and participate.  Thanks for your 

consideration in spreading the word on this event.  Ed WX2R

FOR IMMEDIATE RELEASE

HamSCI Meteor Scatter QSO Party December 12-13, 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 the Geminids meteor showers on December 12-13th for 48 hours from 0000 

to 2400 UTC,

The December activity follows a successful August operating event during the 

Perseids meteor show which generated over 70 logs and wave files from amateur 

radio operators for scientific study.

This is a combination 'special event' and a “contest” to generate contact 

data during meteor scatter events using frequencies on both 10 and 6 meters. 

Contest rules can be found at 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 on specific frequencies. 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.

Currently, we need operators to be active (i.e., CQ-ing) on MSK144; or 

passive, if possible, reporting via PSK Reporter as 'monitors'. The best 

times are early morning hours prior to 10M opening to F2 propagation. Meteor 

scatter propagation occurs well below F2 and is supported in or near the E 

layer where the meteor ionization tracks occur. Saturday mornings are being 

used regularly to announce and coordinate 10M contacts using Ping Jockey 

Central. Announcements are also made on the Front Range Six Meter groups.io 

due to the substantial number of meteor scatter operators in that group.

To be successful, this effort needs operators, both active and passive. If 

you do not have the time to be active, at least set up passive reporting. PSK 

Reporter currently has scarce 10M MSK144 monitors so we need to increase 

those numbers during the early morning hours.

You can find the description of the 2025 HamSCI Meteor Shower QSO Party at

www. hamsci.org/msqp-poster and at www.hamsci.org/msqp.

Please join us in becoming both active and/or passive operator/participants. 

Eventually, the HamSci team will be collecting operator contact information, 

but for now, all that is required is for participants to report through PSK 

Reporter. For more information on the operating guidelines for the activity, 

please go www.hamsci.org/msqp.

HamSCI serves as a means for fostering collaboration between professional 

researchers and amateur radio operators. It assists in developing and 

maintaining standards and agreements between all people and organizations 

involved. Its goals are to advance scientific research and understanding 

through amateur radio activities, encourage the development of modern 

technologies to support this research and provide educational opportunities 

for the amateur community and the public.
