Having had to learn the code to apply for a licence my ability peaked and of late ‘dropped off’ so I spend a lot of time listening to morse and using the excellent G4FON trainer on the PC. ( see my links) I have a collection of keys including four mechanical ‘bug’ keys and numerous ‘straight’ keys. My HF rigs include built in keyers but I have problems with paddles.
It is not easy for some to learn the code but if you can it is very worthwhile, a lot of fun can be had and that first Qso is the one you always remember.
For anybody wishing to learn morse I recommend the G4FON programme. Once learnt you can have a lot of fun on the bands using inexpensive and simple equipment. http://www.g4fon.net/
