UTC during the Summertime period and 0500–2300 UTC during the Wintertime period. These times of year correspond to those of the seasonal clock changes in Germany.(Source: Beacon keeper DK4VW e-mail 18th July 2013) In addition, individual WSPR beacon experiments using powers as low as 1 watt in the UK have led to reception reports from the US and Middle East. South African tests using 5-20 watts have led to reception reports from USA, Europe, Australia and South America. Further research is likely in this area.. As well as amateur radio beacons in the 5 MHz sector, some other non-amateur stations are used informally as propagation indicators. These include: Standard Frequency & Time Stations RWM (Moscow) on 4996 kHz BPM (Xi'an), YVTO (Caracas), HLA (Daejeon, S. Korea), WWV (Colorado) & WWVH (Hawaii) on 5000 kHz VOLMET Aviation Meteorological Information Broadcasts (all USB): "Military One Information VOLMET" on 5450 kHz (previously called 'R.A.F. VOLMET') "South America VOLMET" on 5451 and 5475 kHz "Africa VOLMET" on 5499 kHz "Shannon VOLMET" (Republic of Ireland) on 5505 kHz United Kingdom In the UK (ITU Region 1), the 60-meter segment (also known by its frequency equivalent: 'the 5 MHz band') is available to all UK Full Licensees. It is the subject of active research by radio amateurs due to its propagation properties. This research commenced in August 2002 by means of a special 5 MHz 'Notice of Variation' (NoV) to the Full UK Licence. Five 3 kHz-wide channels, 5258.5, 5278.5, 5288.5, 5398.5 and 5403.5 kHz were allocated, which by mid-2006 had been increased to seven, the additional ones being 5366.5 and 5371.5 kHz (all USB dial frequencies). In December 2012, UK regulator, Ofcom, announced permission for 11 new frequency blocks, following representations from the RSGB and subsequent Ofcom discussions with the 'Primary User' of 5 MHz in the UK, the British Ministry of Defence (MoD). Although the MoD was unable to permit a continuous band, this allocation of seven channels was substantially increased to eleven frequency 'blocks' (or 'bandlets'), integrating the existing channels. These became active on 1 January 2013. Following an Ofcom consultation document on a review of the UK Amateur Licence during 2014, in 2015 Ofcom issued a new UK Amateur Licence which incorporated the UK 5 MHz allocation into the main licence schedule for all UK Full Licensees (Individual, Club, Reciprocal). This came into force on 7 April 2015. The previous 5 MHz
