A Tour of the Ham Bands DC to Daylight
VLF Bands • NOT available in U.S. • 73 Khz • 135-137 Khz. • 160-190 Khz. • 500 Khz. • All limited to very low power – generally Morse Code only -
160 Meter/ 1.8-2.0 Mhz • General Class and higher • Voice and CW • Popular for regional communications at night • Requires very large antennas (240 ft.) for efficient operation – most people use smaller
80 Meters/3.5-4.0 Mhz. • CW 3.5-3.6 (3.525-3.600 Technician) • Digital 3.5-3.6 • Voice (SSB and AM, mostly) 3.6-4.0 • Regional communication in daytime • Long distance possible at night • Dipole antenna 132 feet long
60 Meters / 5 Mhz. • Our newest ham ‘band’ • The only ‘channelized’ ham band • 5 ‘spot frequencies’ shared with Federal government/ Coast Guard/ Homeland Security • 50 watts / antenna limits • Becoming a popular regional band
40 Meters/ 7.0-7.3 Mhz. • CW 7.0 – 7.125 (7.025-7.125 Tech) • Voice 7.125-7.3 • Digital 7.0-7.125 • Popular daytime regional band • Long haul band at night • This band has recently improved due to the removal of shortwave broadcasting
30 Meters/ 10.1-10.15 Mhz • CW/Digital only – 200 watts max • General Class and higher • Excellent worldwide propagation most of the time
20 Meters/14-14.35 Mhz. • General Class and higher • 14-14.15 CW and Digital Only • 14.15-14.35 Voice and SSTV • Our PREMIER daytime HF band • Open in daytime in winter/24 hrs in summer
17 Meters/18.068-18.168 • General Class and higher • 18.068 – 18.110 CW and digital • 18.110-18.168 Voice • Similar propagation to 20 meters
15 Meters/21- 21.450 Mhz • 21-21.2 CW and digital • 21.025-21.200 Technician CW • 21.2-21.45 Voice • Daytime DX band – worldwide propagation • Dipole 22 feet long • Not very useful when sunspots low
12 Meters/24.89-24.99 Mhz • 24.89-24.93 CW and digital • 24.93-24.99 Voice • General and higher • Worldwide communications when open • Greatly affected by sunspots • Eskip – short skip common
10 Meters/28-29.7 Mhz • 28.0-28.3 CW/Digital (Techs, too!) • 28.3 – 29.7 Voice (SSB, AM, limited FM) • 28.3 – 28.5 Technician SSB • 29.0-29.7 FM voice, satellites • Very popular – low power/small antennas, work the world • Eskip • Severely impacted by sunspots
6 meters/50-54 Mhz. • Technician band • 50-50.1 CW only • SSB calling frequency 50.125 Mhz. • 50.110 ‘DX Window’ – stay out of here unless working stations overseas • Primarily a local band • SSB range normally 200 miles • Eskip common in summer, midwinter • Meteor scatter popular here
2 meters/144-148 Mhz • Technician band • Repeaters common • Primarily used for local FM voice • Some use SSB • SSB range 2-300 miles typical • Skip is very unusual • Tropo scatter/ducting
1.25 Meters/222-225 Mhz • Similar to 2 meters • Also includes special 219-220 Mhz. high speed digital allocation • Not as popular as 2 meters • Band not available worldwide • Limited commercial equipment available
¾ Meter/420-450 Mhz. • Our lowest UHF band • FM 438-450 Mhz. 446.0 call frequency • Part of band not available in north • ATV • SSB on 432.100 • Dipole is about 12 inches long • Band shared with many other services • we are SECONDARY here
33CM/902-928 Mhz • U.S. only ham band • No commercial equipment • Many hams use converted commercial radios here • Difficult to convert radios for ‘simplex’
Microwave bands • 2.3 Ghz – weak signal, satellite, 802.11 networking • 3.3 Ghz – 802.11 networks • 5.6 Ghz.- weak signal, 802.11 • 10 Ghz. – weak signal • 24 Ghz – weak signal • Many higher bands – • All are ‘line of sight’ -
