TO many, the staccato sounds coming out of the old-fashioned speaker next to Les Edwards ear are background noise, drowned out by his manual typewriter.
But to Les, it's a language he'll never forget, and he's the best in the world at it.
Les and friend Brian Mullins form part of the "Morsecodians" group, and are in Grafton for their annual visit to the Jacaranda Festival.
"It's 60 years since we learnt Morse code through the Postmaster General," Les said.
"We were in the last school in the same class."
And although time and technology has moved on, Les says the message is as clear as ever.
"We did it professionally so it's ingrained. We both worked in the GPO where the was more than 400 people, and you had a speaker close to you because your speaker would be chatting and there'd be another right next to it."
"We might have slowed down a bit, but you never forget it. It's like a language."
The pair are demonstrating their art form and offer the ability to send a telegram via Morse code, which is received and delivered on a manual typewriter.
"The kids love it. We did a display last month and we had 2000 kids line up to have us send their name," Les said.
While they're not in too much of a rush on this trip, Les is the current Guinness world record holder, part of a pair that sent and received a 160 character message in record pace.
And for those thinking it's all still old fashioned, Les remembers differently.
"On the day we broke the record, that also had us race a man who had held the world record for sending the fastest text message in the world," he said.
"We sent the same message, and even though I'd only seen the message five minutes before, I beat him by eight seconds."
The Morsecodians display is located outside the Telstra Store in Grafton Shoppingworld, and are here until Saturday.
