40 Metres, 7.0 – 7.2MHz
The 7MHz band is one of the most reliable DX bands, with DX possibilities at all states of the sunspot cycle and throughout winter and summer. During the day, contacts around Europe are possible, as well as good intra-UK propagation. At nighttime, the band is an excellent DX band offering worldwide contacts.
Because of its popularity, it can be crowded, especially in Region 1, although the expansion of the band from 7.0 – 7.1MHz to 7.0 – 7.2MHz, originally agreed at WRC-03 has helped.
By 2009, the remaining broadcast stations operating in the 7.1 – 7.2MHz frequency range closed down and the Region 1 band plan was realigned, moving the start of the digital modes segment to 7040kHz, and increasing the space available for all modes. In common with some other bands, Region 1 has designated a contest-free section of the band from 7100-7130kHz during local contests. When operating SSB, please ensure the lowest dial frequency used is 7053kHz (lower sideband), as this will ensure the transmitted spectrum remains within the 2.7kHz all modes segment.
40 metres is also a popular QRP band; the QRP CW centre of activity is 7030kHz.
There are still ongoing issues with data mode operation, particularly PSK, in the CW section of the band. Following the expansion of the data mode segment in 2009, there should be no data mode operation below 7040kHz.
|kHz||7000 7040||7040 7050||7050 7060||7060 7100||7100 7130||7130 7200|
Note that this is only an indication of predominant mode use, see detailed band plan for full definition of permitted modes.
