I used to have a hard time hearing St. John's period, until about four years ago, when they became a regular in the mornings, evenings, and late night. I suspect it's mostly due to less clutter on that band, no more Radio Havana every 20 kHz., but I also wonder if they may have improved their antenna system? The Vancouver station on 6160 was easier for me to hear for years than St. Johns in the mornings.
