40 m band
7 to 7.2 MHz, 200 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.
Where you can transmit

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 |
|---|---|---|---|---|---|
| 7 bis 7,2 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 40 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 |
|---|---|---|---|---|
| 7 bis 7,04 MHz | Telegraphy | 200 Hz | CW | |
| 7,04 bis 7,047 MHz | Digital, narrowband | 500 Hz | Narrowband, digital modes | |
| 7,047 bis 7,05 MHz | Digital, narrowband | 500 Hz | Narrowband, digital modes, unattended stations | |
| 7,05 bis 7,053 MHz | Digital, narrowband | 2700 Hz | All modes, digital modes, unattended stations | |
| 7,053 bis 7,06 MHz | All modes | 2700 Hz | All modes, digital modes | Set LSB no lower than 7.053 MHz |
| 7,06 bis 7,1 MHz | All modes | 2700 Hz | All modes, SSB contests preferred | |
| 7,1 bis 7,13 MHz | All modes | 2700 Hz | All modes, SSB | 7.110 MHz emergency IARU R1 |
| 7,13 bis 7,175 MHz | All modes | 2700 Hz | All modes, SSB contests preferred | |
| 7,175 bis 7,2 MHz | All modes | 2700 Hz | All modes, SSB, priority for intercontinental contacts |
SSB limit
Lowest LSB dial frequency on the 40 m band: 7.053 MHz. The phone range starts at 7.05 MHz, and on LSB the signal sits below 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 40 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 | 7,03 | Meeting point for low power telegraphy. |
| WSPR | 7,0386 | Beacon mode with a few milliwatts. Who hears me where? |
| PSK31 | 7,04 | Keyboard to keyboard, narrow and frugal. |
| RTTY | 7,040 bis 7,050 | Radioteletype. In contests it fills the windows listed. |
| FT4 | 7,0475 | The fast sibling of FT8, mainly in contests. |
| FT8 | 7,074 | Dial frequency in USB, the signal sits 0 to 3 kHz above it. |
| JS8 | 7,078 | Like FT8, but for text instead of reports. Bring patience. |
| Emergency comms | 7,11 | IARU Region 1 centres of activity. Keep clear during an emergency, otherwise normal operation. |
| SSTV | 7,165 | Pictures in slow motion, mostly on USB. |
