17 m band
18.068 to 18.168 MHz, 100 kHz wide. Amateur radio is the primary user here. Only class A (750 W PEP) may transmit. The power limits are set by the Amateurfunkverordnung (AFuV, German amateur radio regulations), the segments are an agreement of IARU Region 1 and the DARC.

Allocation under Annex 1 AFuV
Which class may transmit with how much power. The numbers refer to the additional conditions of use below; they are summarised here, the text of the regulations is binding.
| Range | Status | Class A | Class E | Class N | Provisions |
|---|---|---|---|---|---|
| 18,068 bis 18,168 MHz | primary | 750 W PEP | not allowed | not allowed | 3, 13 |
- 3
- Occupied bandwidth at most 2.7 kHz.
- 13
- Parts of the range are also allocated to the amateur-satellite service.
Band plan segments
Which mode goes where on the 17 m band. This is not a rule but an agreement of IARU Region 1 (on 70 cm the DARC band plan); people stick to it so that telegraphy, digital modes and voice don't get in each other's way.
| Range | Group | max. bandwidth | Mode | Use |
|---|---|---|---|---|
| 18,068 bis 18,095 MHz | Telegraphy | 200 Hz | CW | |
| 18,095 bis 18,105 MHz | Digital, narrowband | 500 Hz | Narrowband, digital modes | |
| 18,105 bis 18,109 MHz | Digital, narrowband | 500 Hz | Narrowband, digital modes, unattended stations | |
| 18,109 bis 18,111 MHz | Special use | Beacons (IBP), beacons only | do not transmit | |
| 18,111 bis 18,12 MHz | Digital, narrowband | 2700 Hz | All modes, digital modes, unattended stations | |
| 18,12 bis 18,168 MHz | All modes | 2700 Hz | All modes, SSB |
SSB limit
Highest USB dial frequency on the 17 m band: 18.165 MHz. The phone range ends at 18.168 MHz, and on USB the signal sits above the carrier shown. The sideband extends up to 2.7 kHz from the carrier, and the radio displays the carrier. Check this frequency
Meeting points on the 17 m band
The band plan says where a mode is allowed. The meeting points say where people actually are: the dial frequency you type into the radio to find someone.
| Mode | Dial frequency (MHz) | Note |
|---|---|---|
| FT8 | 18,1 | Dial frequency in USB, the signal sits 0 to 3 kHz above it. |
| FT4 | 18,104 | The fast sibling of FT8, mainly in contests. |
| JS8 | 18,104 | Like FT8, but for text instead of reports. Bring patience. |
| WSPR | 18,1046 | Beacon mode with a few milliwatts. Who hears me where? |
| IBP beacons | 18,11 | Eighteen beacons in turn, ten seconds each. If you hear one, you know the path is open. Clock for it: /baken |
| Emergency comms | 18,16 | IARU Region 1 centres of activity. Keep clear during an emergency, otherwise normal operation. |
