Polish Radio External Service, according to their website (www.thenews.pl ) the only shortwave transmission for B11 Winter, is on 3955 kHz from 1800-1900 UTC via Sitkunai, Lithuania. This is sad as I was a semi-regular listener to their programs having grown to like them when the CBC's Overnight Service used to carry them at 4:30 AM (local).
