Whenever 98.7 goes to ESPN's national sports feed (at night or on the weekends), the sound quality has been AWFUL for the past two years, and they've done nothing about it. It sounds harsh and "metallic," in lack of a better word. 620 is more tolerable with ESPN programming because the AM sound quality masks any issues. Why Bonneville keeps ignoring this issue is beyond me, because it's TOUGH to listen to the national content for long periods of time on 98.7.
