The RSGB and Ofcom have released the notes of there meeting helpd on 12 June 2014.

One of the issues raised was the allocation of a K-Regional Secondary Locator for Cornwall (Kernow)

Many areas have their own Regional Secondary Locator (RSL) codes to create distinctive prefixes – eg D = Isle of Man

The Shetland Islands (Zetland) uses Z character, but only for Amateur / Ham Radio Contest Stations but not for normal stations. Working stations with such callsigns seems to be popular with Prefix collectors.

The Poldhu Amateur Radio Club have submitted a proposal to Ofcom to introduce K as an optional RSL for amateur stations operating from Cornwall. Ofcom have said they will respond in due course.
