On my radio, I manually tune the frequency. Although the sound in between radio stations is not pleasant, it tells me there's plenty of space left for new waves.
My weekly email letter is nothing like a fully functioning radio station with an audience, weekly schedule, music library, 'toilet tracks' and pool of voices - but I learned it has a frequency.
After sending out my first email letter, a friend from overseas replied: "We need to catch up as we seem to be on the same wave without meeting in the surf." Only because I started making a wave, could others hear it.
Do you mostly tune into radio stations, or can we hear your wave amongst the noise?
