Yes I first heard this on 3UZ in 1979. I also heard it in 1989 one Sunday morning in July on some FM station just outside Sydney. Not sure if it was a community station.
Sorry can’t remember anything about it except that I heard it on 3BO on a Sunday evening in January 1978 and some of the songs that were on that countdown. I may have also heard it in 1977 and 1979 but not sure what station.
Cool Country 2KA in Penrith (1476) still airs American Country Countdown, now hosted by Ryan Fox. Kix Brooks from US country music duo Brooks and Dunn was a former host.
From memory, it was a sudden closure. On air one day, gone the next! It got a fair bit of publicity at the time on the radio news websites.
Maybe whoever was in charge didn’t bother to let the company producing the American Country Countdown know of the stations closure, although you’d think they’d know - these shows wouldn’t be free and wouldn’t have been taking payments from Cool Country for at least 10 years.
It was quite odd… they weren’t happy about being on 1476 because of night skip interference from 4ZR Roma… so they requested a frequency change, and were given one, to 1386, but never moved… and I think they went off air shortly after the frequency change was granted.
Just out of interest, it is often claimed that 2SB was Australia’s first licenced broadcaster (on November 23 1923), which is true for MW, however the first licence granted was in December 2022 to 2CM, which broadcast on 214 kHz.
there’s the TCM top 30 (Australian Christian Music Charts) and also 20 the countdown Magazine (American Chrisitan music countdown). of which i only think 20- the countdown magazine is still on air - vision plays it on a saturday afternoon and also very early sunday morning
7BU in the late 1970s used to take a weekly Top 40 show with the host being Phil Sutton in Sydney. Looking at Trove, I found a radio show on 2CC for the National Top 40 with Phil Sutton from 1975.
Weeknights during the HOT HIT era I’d listen to ‘The Survey’ with Shirl & Irvine which was a nightly countdown (later to become Chart Attack - with Craig Huggins).
