Frequency Description
Below 150 kHz Mostly CW and RTTY. Also used for the USN "Omega" sub navigation system, pm 10.2, 12, and 13.6 kHz. Russian subs use 15.625 kHz (not to be confused with 15,625). The SAC operates stations in this range too, like 29.5 and 37.2kHz. If you tune down enough you might hear WWVB!
150 - 540 kHz Longwave. mostly in CW, some on AM. 500kHz and 512 kHz are international maritime distress frequencies. 512 kHz is a contact only frequency. Has a lot of beacons, and some aeronautical WX beacons and a few BC stations. 530kHz is a travel and highway safetey information frequency. MW now includes 520 - 540 in this rage.
540 - 1600 kHz Mediumwave (AM). This is now considered to be 520 to 1710 kHz. 1600 to 1800 used to be considered used for radio navigation systems. This change happened in the 1990's.
1600 - 1800 kHz Now included in MW up to 1710 kHz. Inbetween stations which are every 10kHz in the US, you might hear seismic beacons, some rare cordless telephones (maybe?), and tropical MW stations.
1800 - 2000 kHz 160m Amateur Radio. Mainly CW but also has SSB. Supposed to be good in wintertime.
2000 - 2850 kHz Maritime. Mostly SSB, some CW and RTTY. 2182 is a maritime "phone" distress channel. You can hear ship to ship on 2082.5, 2638 and 2782 kHz. USCG has stations on 2670. This range also includes WWV and WWVH in Hawaii. This range also includes 120m Shortwave (SW) from 2300 to 2498 kHz.
2850 - 3150 kHz Has mostly "VOLMET" stations and some other Aeronautical HF, mostly in SSB primarily USB and some CW. Good sunset to sunrise.
3150 - 3400 kHz Allocatedd for fixed stations and some mobile stations. You can supposedly find FEMA on 3341 and the US Dept. of the Interior in the Pacific region on 3385 kHz. CHU on 3330 kHz. And a Tropical (DX) band called 90m SW, from 3200 to 3400kHz. Good for rare DX.
3400 - 3500 kHz Aeronautical Mobile. Some VOLMET stations, like 3485 kHz.
3500 - 4000 kHz 80m Amateur Radio band. Also 75m Amateur Radio. Mostly CW and RTTY (with some voice, usually LSB). A standard time station in Equador, on 3810 kHz. Europe and Africa BC on 3900 - 4000 kHz.
4000 - 4063 kHz Fixed station band. Used for MARS Military afiliated amateur radio stations.
4063 - 4438 kHz Maritime HF band. Usually USB voice. some CW, some RTTY. 4125 kHz is a SSB calling frequency.
4438 - 4650 kHz This is a band allocated for both fixed and mobile service. You might find the USAF operating in USB on 4449 kHz.
4650 - 4750 kHz Another Aeronautical band. Mostly for VOLMET stations.
4750 - 4995 kHz 60m Tropical BC (DX) SW Band. Good through 2300 - 0100 UTC and sometimes around 0600 - 1000 UTC.
4995 - 5005 kHz Set aside for standard time and frequency stations, including WWV and WWVH on 5000 kHz.
5005 - 5450 kHz Mainly for fixed and land mobile stations. Some tropical BC DX stations here. Try listening for SSB, CW and RTTY.
5450 - 5730 kHz The first 30kHz of this is shared, for Aeronautical and fixed stations. the rest is Aeronautical HF. Mostly VOLMET. Try on 5520 and 5550 kHz in the Carribean area, and also 5598 and 5649 kHz in the North-Atlantic to Europe, etc.
5730 - 5950 kHz Allocated for Fixed stations. Usually SSB, CW and RTTY. The US Weather service has a station in USB on 5923. The US Dept. of Energy uses 5948 kHz. NASA uses 5810 in USB (best in the 1,000mi around Florida).
5950 - 6200 kHz 49m SW band. Great from 0500 - 0800 UTC and onwards. This one is jam packed with BC!
6200 - 6525 kHz Allocated to Maritime comms. Mostly SSB in USB mode, some CW and RTTY too. 6218.6 in USB is for inland traffic and the USCG. 6221.6 is also a great channel.
6525 - 6765 kHz Another Aeronautical band, mostly VOLMET. You might find the USAF using 6670, 6683, and 6712 and 6738 in USB.
6765 - 7000 kHz Mainly for fixed stations. Lots of CW, and RTTY and misc. data signals.
7000 - 7300 kHz Shared. Both 40m Amateur Radio band and 41m SW band. Amateur radio operators use SSB (maybe usually LSB and sometimes US) and sometimes CW and RTTY. Even SSTV!
7300 - 8195 kHz CHU in Canada is 7335 kHz. Interpol stations on 7401 in RTTY. The US Customs service might use 7527 kHz in USB.
8195 - 8815 kHz Maritime band. Mostly CW, some USB. 8257 is a ship calling frequency. 8291.1 and 8294.2 kHz are good in USB. 8364 is for CW and is a distress and emergency frequency.

9500 - 9900 kHz This is the 31m SW Band. Great as the evening goes onwards. Good during the day in the wintertime. Some fading during 0500 - 0600 UTC.
9900 - 9995 kHz Look for RTTY here. You'll find more out-of-band (OOB) BC here lately though.
9995 - 10005 kHz Reserved for time standard frequency stations like WWV and WWVH.
10005 - 10100 kHz Yet another aeronautical band 10072 and 10075 kHz in USB are used by airlines for noncritical comms, mostly to and from airports.
10100 - 10150 kHz 30m Amateur Radio band. CW and RTTY only due to space limitations.
10150 - 11175 kHz Has some of the least known util stations... look for BC stations in SSB for feeder broadcasts. Look for Interpol stations on 10295 in RTTY.
11175 - 11400 kHz Another aeronautical HF band. Look for USAF on 11182 kHz. VOLMET on 11279. Might hear some in CW on 11312 kHz.

11650 - 11975 kHz 25m SW Band. Great band! Lots of great stations.
11975 - 12330 kHz Band conditions similar to 25m. Some IBC's here too. Look for FEMA in USB on 12216. Look for IBC feeder stations in SSB too.
12330 - 13200 kHz Maritime Allocation. Mostly USB. Try 12429.2 in USB. Mostly CVW and RTTY signals here though.
13200 - 13360 kHz Aeronautical HF Band. Mostly used by the USAF in USB. Try 13201, 13204, and 13241 kHz.
13360 - 13800 kHz 22m IBC SW band. Band can get crowded. Try the early afternoon to evening hours.
13800 - 14000 kHz Look for the Red Cross operating on 13915 kHz and 13397 kHz in USB. The FCC might use 13990 in RTTY.
14000 - 14350 kHz The 20m Amateur Radio band. Good DX band. The first part usually has CW and RTTY. The rest has mostly SSB in USB and some SSTV.
14350 - 14490 kHz This is a fixed station allocation band. You'll find a variety of modes there. CW, RTTY, and sometimes Fax. Look for a Austrailian research station operating on 14415 in USB and an Interpol for Africa on 14827 in CW.
14990 - 15010 kHz Standard time and frequency allocation throughout the world. Try listening for other stations around your LT sunrise.
15010 - 15100 kHz This is a very narrow band Aeronautical HF band. Look for the USAF operating in USB on 15041 and 15048. Try also the range for IBC 15070 - 15090 for some OOB stations next to 19m.
15100 - 15600 kHz 19m IBC SW Band. Not very good band during this low period of the solar cycle and sunspot activity. Try during the daytime. Other fixed stations in the upper part.
