S-12? 110 kc -? 11 Mc
S-22? 144 kc -? 18 Mc
S-22A 110 kc - 18 Mc
S-30 ? 220 kc -? 3 Mc
S-98 ? 170 kc - 10 Mc
SX-117 (w/HA-10) - 85 kc- 3Mc
S-118? 190 kc - 50 Mc

? 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. ?
