The portion of the band used for phone (voice) communications is sometimes referred to as 75 meters.80 meters is the most popular band for regional communications networks through the late afternoon and night time hours. It is usually reliable for short to medium distance contacts, with average distances ranging from local contacts within 200 miles/300km out to a distance of 1,000 miles/1,600km or more, depending on atmospheric and ionospheric conditions."@en }
