Tim G4VXE posted an interesting ‘random’ thought about one suggestion he’d heard recently on air to raise your CW speed:
“one of the ways to improve your speed and competency is to listen to as much morse as you can – for example, have the rig running whilst your watching TV or reading. It’s almost as if the subconscious brain starts to process it and it becomes a ‘background process’.
This will help you if you want to be able to send/receive morse at the same time as doing something else.”
It can’t hurt – apart from driving all those around you crazy – and convincing them of all the doubts they already had about you! But maybe that’s what the headphones are for.
