I am emailing you as you either publish Amateur Radio Contests or you develop contesting software.
The MDC QSO Party is being changed and will be a one day event now and this year it will be Saturday, August 11 from 1600z to August 12 0400z (Noon to Midnight EDT).
I've attached the updated rules if you need them. The web site will have the new rules posted soon, but the site already mentions it is now a one day event.
Please forward this email as you see fit.
Let me know if you have any questions.
Mike Watterson - K3MAW
MDC QSO Party Chairman
