'Notice-of-Variation' (NoV) is now no longer required, however it is still a licence requirement that the Licensee shall only operate on the band to the extent that the Licensee can be contacted on a telephone which is located in close proximity to the Station. There are some additional restrictions which still apply: Maximum Antenna Height is 20 metres (65') AGL (above ground level) Neither mobile nor maritime mobile operation permitted Power is limited to 100 watts PEP (not to exceed 200 W EIRP) Maximum Permitted Transmission Bandwidth is 6 kHz (double sideband) All Modes are allowed. This provision is on a Secondary, non-interference (NIB) basis. Instructions on amateur radio 60 m operations in the UK are provided in the RSGB '5 MHz' web pages and at the Ofcom Amateur Radio Section. The UK 5 MHz Frequency Blocks are as follows (all in kHz): As well as Analogue Voice and CW, the band in the UK is also used for Digital Communications in modes such as PSK31, Olivia, MFSK, MT63, SSTV, Hellschreiber, JT65A, JT9, FT8 and FT4 success being shown with most modes, despite the problems that can result from ionospheric distortion, particularly to the phase of the signal. The Summits on the Air (SOTA) program uses 5 MHz for a number of activations, with considerable activity from some operators. In the UK, 5 MHz is also used for one of the weekly RSGB (Radio Society of Great Britain) news bulletin broadcasts under the special transmit-only callsign GB2RS. The transmission takes place on Sundays at 1500 hrs UTC on 5398.5 kHz USB. The intention is to prove that 5 MHz provides a reliable vehicle for a national news broadcast which is able to cover the whole of the UK. After the news a net is carried out with signal reports exchanged, both with UK listeners and others further afield. This band is unique in the United Kingdom insofar as UK 5 MHz operators may also communicate under controlled operating conditions with UK Military stations or UK Military Cadet Youth Organizations with links to the MoD using these frequencies. They use MoD allocated call signs, which differ significantly from those issued by Ofcom to the Amateur Radio Service in the UK. In 2016, the RAFAC (RAF Air Cadets) introduced and coordinate several events during the year called 'Exercise Blue Ham' in which Military Cadets exchange radio contact information with amateur stations on
