1991 13th January saw Russian troops invade Lithuania. . .
All radio traffic was disrupted, but Lithuanian amateur radio operators managed to tell the world about the invasion.
Lithuanian radio amateurs will operate special event stations to mark the 20th occasion of the “January 13th”.
Have a go at contacting special event stations with the LY13 prefix from 2011-01-12 22:00 to 2011-01-27 22:00 UTC:
