Longwave Non-Directional Beacons (NDBs)

Radio beacons are simply transmitters that repeat some identifying signal over and over. Most of them are for navigational purposes.

There are thousands of beacons operating in the longwave radio spectrum, generally between 200 and 450 kHz, for the purpose of aeronautical and marine navigation.

Most of the identifications come from Paulo Santos' most excellent AirNav page.

Some of the gaps in AirNav's coverage have been filled by loggings from these longwave DX pages (and others; dead links removed 1/27/07):

My Longwave Log for 2007

My location: 10 miles northwest of Gulfport, Mississippi, USA; approximately 89.11W, 30.47N. Equipment: Yaesu FT-1000, 160 meter inverted L with 45' vertical section. Prior to mid-1999 I used a Sony ICF-2010 and Grove Minituner. Prior to Hurricane Katrina I had a 325' Beverage antenna, which one day I will replace.

Loggings for the current season are on this page.
Previous seasons' logs are linked below.
Merged list of ALL loggings since 1996

Loggings for '02-'03 (just a few)
Loggings for '99-'00
Loggings for '98-'99
Loggings for '97-'98
Loggings for '96-'97

Notes

Back in the saddle [01/27/07]: I've not been active in NDB DXing for the past several years. Power line noise had gotten horrible around here and I lost interest. Recently I put up inverted L antennas for 160 and 80 meters which revived my interest in low-band DXing. Last night I took a spin through the NDB band and found it pleasantly quiet. I hope it stays that way.
