At the request of the RSGB, Ofcom, some English stations wishing to retain their usual Regional Secondary Locator to identify their DXCC entity may use the suffix '/70' to celebrate the Queen's Platinum Jubilee (70th anniversary) of Queen Elizabeth II.

It is also permitted to use the "/70" suffix with the "2Q/GQ/MQ" prefix if desired throughout the month of June.

Also, look for Dainius, M0HMJ, to be active as MQ5W during various contests in June to commemorate the Platinum Jubilee of the Accession of Her Majesty.

Also, look for GB2PJE by the Thames Amateur Radio Group (TARG) operating from a location near Battlesbridge in Essex and the callsign will be in use by TARG members and visitors under the supervision of a Full Licence Holder.
