My introduction to radio came when I somehow convinced by parents to buy me a Sharp radio Cassette player when I was in primary school. Despite its tiny terribly inaccurate dial, looking back it was amazing what it could pull in on the MW and three SW bands. The first station I discovered was 4IP. There was no other station that could come close. I used it to record songs and keep cassettes over the years. However, I also discovered the out of area stations that would come in at night and started to record snippets of their branding.
Stations form Sydney and adjacent areas were always strong like 2SM, 2UE, M-NX, 2CA etc plus Victorians 3XY, 3DB, 3NE and 3LO. This was a time when many commercial and all ABC stations closed around midnight leaving great DX opportunities. One problem was working out what the stations were as resources like ACMA databases were hard to obtain for a school kid. Then I found Electronic Australia that for many years published a list of stations that even included their ERP. Later there was also World Radio TV Handbook that was a great source for SW.
Radio was a great connection to the world and the best place to keep up with news. Radio from other countries was always interesting but difficult to receive on AM. In addition to the usual Pacific nations, it was a big day when US stations were received as well as the big Mexican stations at Tijuana. American Forces Radio (AFRTS) on SW also gave a taste of the US with direct feeds from commercial networks. But with SW you can receive almost any country with a transmitter plus Radio Australia that was a great service.
When FM came to Brisbane it was in the form of 4ZZ on 105.7. The next closest station was 2NCR that could just be received in high locations. Double Zed was a disappointment with its low power from a tower on the Schonell Thearte and non-commercial content. FM 104 introduced themselves with great weekends like Beatles A-Z, Rolling Stones A-Z etc but over the years I found that FM stations from adjacent areas were better choices for me.
