Here is a guide that I found online. It explains what you can expect to hear on various bands in plain english. Might be helpful to some people who are new to shortwave.
1700 to 1800 kHz: This is a "grab bag" of miscellaneous radio communications, mainly beacons and navigation aids. You may hear several transmitters that sound like chirping crickets; these are floating beacons used to mark fishing and offshore oil exploration locations.
1800 to 2000 kHz: This is the 160-meter ham radio band. Most voice communications will be in LSB, with best reception at night during the fall and winter months.
2000 to 2300 kHz: This range is used maritime communications, with 2182 kHz reserved for distress messages and calling. There are also several regularly scheduled maritime weather broadcasts buy U.S. Coast Guard stations. Most activity will be in USB, and best reception is at night.
2300 to 2498 kHz: This is the 120-meter broadcasting band, mainly used by stations located in the tropics. However, the FCC has allowed WWCR in Nashville, Tennessee to broadcast here and others may follow.
2498 to 2850 kHz: More maritime stations are found here, as well as standard time and frequency stations WWV and WWVH on 2500 kHz.
2850 to 3150 kHz: This band is used mainly by aeronautical stations in USB. Several stations broadcasting aeronautical weather bulletins, and you can also hear traffic between airports and airplanes aloft.
3150 to 3200 kHz: This range is allocated to fixed stations, with most communications in RTTY.
3200 to 3400 kHz: This is a very interesting segment. This us the 90-meter broadcasting band, used mainly by stations in the tropics. Canadian standard time and frequency station CHU can be heard on 3330 kHz. Several fixed stations also use this range, including several associated with various agencies of the U.S. government. Best reception will be at night.
3400 to 3500 kHz: This range is used for aeronautical communications in USB.
3500 to 4000 kHz: This is the 80-meter ham radio band. The 3500 to 3750 kHz range is used for CW and RTTY communications, and the rest of the band is used for LSB voice. The 3900 to 4000 kHz range is used for broadcasting in Europe and Africa. Best reception is at night.
4000 to 4063 kHz: This is a fixed station band, mainly used by military forces for SSB traffic.
4063 to 4438 kHz: This is a band used for maritime communications in USB, with 4125 kHz being used as a calling frequency.
4438 to 4650 kHz: This range is mainly used for fixed and mobile stations in USB.
4750 to 4995 kHz: This is the 60-meter broadcasting band, used mainly by stations in the tropics. Best reception is in the evening and night hours during the fall and winter. In winter, stations to the east of you begin to fade in an hour or two before your local sunset, and stations to the west of you don’t start to fade out until an hour or so after your local sunrise.
4995 to 5005 kHz: This range is allocated internationally to standard time and frequency stations. In North America, you’ll mainly hear WWV and WWVH on 5000 kHz.
5005 to 5450 kHz: This range is a real jumble! Several broadcasting stations are found in the lower part of the segment, and fixed and mobile stations in SSB, RTTY, and CW are found throughout this band. Best reception is during the evening and night hours.
5450 to 5730 kHz: This is another band for aeronautical communications in USB.
5730 to 5950 kHz: Another jumble of different stations! For years, this band has been used by fixed stations of the U.S. government for communications in USB and RTTY. However, several broadcasters are also showing up here.
5950 to 6200 kHz: This is the 49-meter broadcasting band, and is loaded with signals from late afternoon to a couple of hours after your local sunrise.
6200 to 6525 kHz: This is a very busy band for maritime communication in USB and various FSK modes like AMTOR and FEC.
6525 to 6765 kHz: This is another busy band, this time for aeronautical communications in USB. Best reception is during the evening and night hours.
6765 to 7000 kHz: This segment is allocated to fixed stations, with signals in SSB, CW, FAX modes, and miscellaneous digital modes.
7000 to 7300 kHz: The 7000 to 7100 kHz range is allocated exclusively to ham radio worldwide, although an occasional broadcaster will show up here. The 7100 to 7300 kHz range is allocated exclusively to ham radio in North and South America, but is used for broadcasting in the rest of the world. Several station transmit programs intended for reception in North and South America in this range. As a result, interference is often very heavy here during the night and evening hours. Hams use CW and RTTY from 7000 to 7150 kHz, and mainly LSB from 7150 to 7300 kHz. Best reception is from the late afternoon to early morning, although some hams can usually be heard here around the clock.
7300 to 8195 kHz: This segment is mainly used by fixed stations, such as Canadian standard time and frequency station CHU on 7335 kHz, although several broadcasters can be found in the lower reaches. Various FSK (RTTY) and digital modes are used.
8195 to 8815 kHz: This is a busy maritime band from the late afternoon until early morning, with most traffic in USB and FSK modes.
8815 to 9040 kHz: This is another aeronautical communications band, with traffic in USB. Several stations hear broadcast aeronautical weather reports.
9040 to 9500 kHz: This range is used mainly by fixed station in various FSK and digital modes, but it is also used by several international broadcasters.
9500 to 9900 kHz: This is the 31-meter international broadcasting band, and is packed with stations from around the world. Best reception is usually from mid-afternoon to around mid-morning, although some stations can be heard here throughout the day, especially in winter.
9900 to 9995 kHz: Several international broadcasters use this range along with fixed stations using FSK modes.
9995 to 10005 kHz: This is set aside for standard time and frequency stations, like WWV and WWVH on 10000 kHz.
10005 to 10100 kHz: This range is used for aeronautical communications.
10100 to 10150 kHz: This is the 30-meter ham radio band. Because it is so narrow, operation here is restricted to CW and RTTY.
10150 to 11175 kHz: This segment is used by fixed stations. In addition to various FSK and digital modes, you may hear several international broadcast stations being relayed in SSB. These "feeder" stations are used to send programming to relay sites not served by satellite downlinks.
11175 to 11400 kHz: This range is used for aeronautical communications in USB.
11400 to 11650 kHz: This segment is mainly used by fixed stations in FSK and digital modes, but some international broadcasters also operate here.

13800 to 14000 kHz: This is used by fixed stations, with most communications in FSK modes.
14000 to 14350 kHz: This is the 20-meter ham radio band. The lowest 100 kHz is reserved for CW and RTTY use, with USB popular in the rest of the band (although U.S. hams cannot transmit in SSB below 14150 kHz). Best reception is during the daytime and early evening.
14350 to 14990 kHz: This segment is used by fixed stations, primarily in FSK and digital modes. Canadian standard time station CHU is also found here, on 14670 kHz.

18168 to 19990 kHz: This large band is used by fixed stations, with a few maritime stations also found here. Most traffic is in FSK and digital modes. An interesting frequency is 19954 kHz, used for decades as a beacon frequency by Soviet/Russian manned spacecraft. Reception in this range will usually be limited to daylight hours.
19990 to 20010 kHz: This segment is reserved for standard time and frequency stations, like WWV on 20000 kHz. Reception here is usually possible only in daytime.
