I've even heard WWFE Miami with it. To be truthful, WWFE was still on daytime power, and it was at sunset, so that wasn't a big deal either. My wife uses my GE SR II at our cottage to listen to 650-WSM's Gran Ole Opry on Saturday nights. My SR II has an excellent ferrite antenna coupled to an RF amplifier stage. That gives it better than average sensitivity and nulls and it consistently performs well.
GEs are very good but many people attribute all kinds of incredible catches to the radio itself.
Propagation conditions and luck in listening at the right time are equally important. The following is a repost of an article that I originally wrote in the FIDO Shortwave Echo almost two years ago. Although I wrote about the GE SR II, the SR III shares many attributes with its predecessor. I posted it originally a month after returning from the 1995 Newfoundland DXpedition during which we logged about 90 countries on mediumwave. We used communications receivers attached to several thousand feet of Beverage antennas.
