*These bands are reserved for sta- tions in tropical areas.

**Interference is heavy in the 41m band (7.100–7.300 MHz) because am- ateur radio operators and international stations share this range.

Aircraft Frequencies

Aircraft on international routes some- times use SW. Most transmissions are in SSB, although you can still hear some AM 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.
