Re: Furthest daytime DX on ULR?


Going on a 2 hours after sunrise to 2 hours before sunset definition of "daylight reception times", the Saudi Arabian station on 1521 can show up at coastal sites in Massachusetts as early as 1 p.m. local in December: 3+ hours pre-sunset, so I guess that would qualify. Distance about 5000 miles / 8000 km.

For groundwave, when Turks & Caicos was running full power on 530, it could be heard on high-sensitivity 'barefoot' portables and, with a loop coupled, on just about anything, at West Dennis Beach, Cape Cod. Distance about 1400 miles / 2240 km. WOKV 690 Jacksonville, FL, at about 1100 miles / 1760 km is audible there at similar strength on radios selective enough to dodge slop from WRKO 680 and IBOC from WOR 710.

Thus far, WGN 720, Chicago IL (1023km/636mi) is the furthest station I've heard with an ULR. It was audible, but only partially readable, at lunchtime today. The station is heard occasionally from October into March.

In a time long, long ago - that is before URL'S - I logged CBK 540, Watrous SK (1815km/1128mi) and WJR 760, Detroit MI (1381km/858mi) at mid-day during the winter. The reception of WJR resulted in a QSL card. It's no longer possible since the FCC allowed the band to become cluttered with signals.

The most distance station heard on a daily basis is KLTT 670, Commerce City CO (750km/466mi). Others are KWMT 540, Ft. Dodge IA (734km/456mi) and WNAX 570 Yankton SD (726km/451mi). It's normally possible to hear stations in nine states at mid-day.

I imagine those listening along the coasts can hear stations at far greater distances. I read reports of some amazing distances.
