Listening Guide

Longwave Band

The 153–279 kHz range is known as
the  longwave  band.  Most  stations  in
this  range  serve  as  beacons  for  air-
craft and marine navigation by contin-
uously  transmitting  their  call  letters.
Reception  for  this  range  is  best  be-

tween 6:00 PM and midnight (your
time).

Some ships also use this range, with
500 kHz set aside as an international
distress and emergency station.

Most stations in this range use CW.

Listening Guide

The following list contains some of the more frequently heard stations. All sta-
tions are broadcast in English unless otherwise specified. You can hear these
stations throughout North America. However, reception varies based on the sea-
son, time of day, and a number of other conditions. This information can change
at any time. For sources of yearly, up-to-date listings, see “Reference Sources”
on Page 21.
