Amateur bands
The bands HamQSO follows, from 160 metres to 70 centimetres. Each page gives the edges in the three ITU regions, the band plan and the frequencies where the digital modes gather, plus what the band does and when.
- CW
- Digital modes
- Phone (SSB)
- Beacons
- Satellites
- FM and other modes
- 160m1.810–2.000 MHz
Top band: the lowest HF band, a night-time band for long hauls and the hardest DXCC of all.
- 80m3.500–3.800 MHz
The 80 metre band: regional contacts by night, nets and the first long-distance openings of winter.
- 60m5.3515–5.3665 MHz
The 60 metre band: a narrow secondary allocation, reliable for regional contacts day and night.
- 40m7.000–7.200 MHz
The 40 metre band: open around the clock, the most versatile HF band for both local and DX contacts.
- 30m10.100–10.150 MHz
The 30 metre band: a narrow WARC band for CW and digital modes, open day and night.
- 20m14.000–14.350 MHz
The 20 metre band: the main DX band, open to long distance through most of the day in any part of the cycle.
- 17m18.068–18.168 MHz
The 17 metre band: a WARC band with 20 metre reach and a fraction of the crowd.
- 15m21.000–21.450 MHz
The 15 metre band: a daylight DX band that comes alive with the solar cycle.
- 12m24.890–24.990 MHz
The 12 metre band: a narrow WARC band that rewards a high solar cycle.
- 10m28.000–29.700 MHz
The 10 metre band: the widest HF band, spectacular in a high solar cycle and with sporadic E in summer.
- 6m50.000–52.000 MHz
The 6 metre band: the magic band, mostly quiet, then suddenly open across the continent.
- 2m144.000–146.000 MHz
The 2 metre band: local FM and repeaters, plus SSB and CW contacts far beyond the horizon.
- 70cm430.000–440.000 MHz
The 70 centimetre band: repeaters and satellites, and weak-signal work at the bottom of the band.
