Radio Shack DX-398 Aircraft Frequencies, Ships and Coastal Station Frequencies, Longwave Band

Aircraft Frequencies

Aircraft on international routes some- times use SW. Most transmissions are in SSB, although you can still hear some MW transmissions. Here are some bands where you might hear air- craft communications.

4,650–4,750 kHz

6,545–6,765 kHz

8,815–9,040 kHz

11,175–11,400 kHz

13,200–13,360 kHz

15,010–15,100 kHz

17,900–18,030 kHz

Ships and Coastal Station Frequencies

Most transmissions from ships and coastal stations are in SSB and CW. You can hear these transmissions in the following bands.

2,000–2,300 kHz*

4,063–4,139 kHz

4,361–4,438 kHz

8,195–8,181 kHz

12,330–12,420 kHz

13,107–13,200 kHz

16,460–16,565 kHz

*The Coast Guard and small boats use this band, with 2,182 kHz set aside as the international distress and emer- gency channel.

Time Standard Frequencies

The following frequencies announce the exact time of day at specified inter- vals.

WWV in Fort Collins, Colorado:

2,500 kHz

5,000 kHz

10,000 kHz

15,000 kHz

20,000 kHz

CHU in Canada: 7,335 kHz

VNG in Australia: 4,500 and 12,000 kHz

Longwave Band

The 150–519 kHz range is known as the longwave band. Most stations in this range serve as beacons for aircraft and marine navigation by continuously transmitting their call letters. Recep- tion for this range is best between 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 (Morse code), although some use AM voice transmission for weather broad- casts.
