Hi, I have to be able to send / receive morse for my Radio Amateur's A Licence. It was suggested to me that I learn it in letter groups, eg all letters beginning with a single dot then, two, thre etc, repeat for those starting with a single dash etc. There are also slow morse transmissions for people wishing to learn morse. These are provided free by the Radio Society of Great Britain and the dates and times can be found on their website at
