From: [email protected] [mailto:[email protected]] On Behalf Of Waldo Magnuson via groups.io ? ? ¡¡¡¡¡¡¡. ? There are many LF non-directional beacons (hundreds in Europe, dozens in the US and Canada) in the band from 200 KHz to 550 KHz. ?There is a forum that has a contest the last weekend of each month logging NDBs. ?Distances range from close (10 miles) to 2 or 3 thousand miles away. ?I use an iCom R-75 receiver, a narrow audio filter (7 Hz BW), a 10 foot diameter amplified loops, and earphones. ? ?
