15 m band
21 to 21.45 MHz, 450 kHz wide. Amateur radio is the primary user here. Class A (750 W PEP) and E (100 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 |
|---|---|---|---|---|---|
| 21 bis 21,45 MHz | primary | 750 W PEP | 100 W PEP | 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 15 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 |
|---|---|---|---|---|
| 21 bis 21,07 MHz | Telegraphy | 200 Hz | CW | |
| 21,07 bis 21,09 MHz | Digital, narrowband | 500 Hz | Narrowband, digital modes | |
| 21,09 bis 21,11 MHz | Digital, narrowband | 500 Hz | Narrowband, digital modes, unattended stations | |
| 21,11 bis 21,12 MHz | Digital, narrowband | 2700 Hz | All modes except SSB, digital modes, unattended stations | |
| 21,12 bis 21,149 MHz | Digital, narrowband | 500 Hz | Narrowband | |
| 21,149 bis 21,151 MHz | Special use | Beacons (IBP), beacons only | do not transmit | |
| 21,151 bis 21,45 MHz | All modes | 2700 Hz | All modes, SSB |
SSB limit
Highest USB dial frequency on the 15 m band: 21.447 MHz. The phone range ends at 21.45 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 15 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 |
|---|---|---|
| CW QRP | 21,06 | Meeting point for low power telegraphy. |
| PSK31 | 21,07 | Keyboard to keyboard, narrow and frugal. |
| FT8 | 21,074 | Dial frequency in USB, the signal sits 0 to 3 kHz above it. |
| JS8 | 21,078 | Like FT8, but for text instead of reports. Bring patience. |
| RTTY | 21,080 bis 21,110 | Radioteletype. In contests it fills the windows listed. |
| WSPR | 21,0946 | Beacon mode with a few milliwatts. Who hears me where? |
| FT4 | 21,14 | The fast sibling of FT8, mainly in contests. |
| IBP beacons | 21,15 | Eighteen beacons in turn, ten seconds each. If you hear one, you know the path is open. Clock for it: /baken |
| SSTV | 21,34 | Pictures in slow motion, mostly on USB. |
| Emergency comms | 21,36 | IARU Region 1 centres of activity. Keep clear during an emergency, otherwise normal operation. |
