40 meter tape
The 40 meter band or 7 MHz band covers the frequencies from 7.0 MHz to 7.2 MHz in ITU regions 1 and 3 and the range from 7.0 MHz to 7.3 MHz in shortwave ITU region 2. It is primarily assigned to the amateur radio service and named after the approximate wavelength .
Propagation conditions
This band enables long-distance connections ( DX ) from late afternoon to early morning as well as short-range connections using NVIS during the day, especially during times of high solar activity . Due to the good propagation conditions - albeit attenuated by the D-layer during the day - it is also known as the "European band".

Band plan
The amateur radio - band plan sees the IARU region 1 as follows:
Frequency range | Max. Bandwidth | use |
---|---|---|
7.000-7.040 MHz | 200 Hz | CW, activity center QRP 7030 kHz |
7.040-7.047 MHz | 500 Hz | Narrow band, digimode |
7.047-7.050 MHz | 500 Hz | Digimode, automatically operating stations |
7.050-7.060 MHz | 2700 Hz | all operating modes, digimode |
7.060-7.100 MHz | 2700 Hz | all operating modes |
7.100-7.200 MHz | 2700 Hz | all modes of operation, activity center image transmission 7.165 MHz |
