As mentioned a while ago
Stations within Cornwall are being allowed to add a K in there call sign.
From Jan 1st mid night till Dec 31st mid night 2016.
This only applies to Cornish based stations and not visitors to Cornwall and also not for use out side Cornwall.
So all being well will be using the call MK3FEH.
Hopefully from a few Cornish Summits as well as MK3FEH/p and a few WAB,s Cornish Squares is my intention for 2016
More details on this web site
For those within Cornwall to apply for the Extra letter is via the RSGB web site
Roll on 2016
