A couple of Perth FM radio history from The Radio Vault.
First is an aircheck of 94.5 KYFM (now Mix 94.5) from Perth in mid-July 1991, just a month & a half after it converted from AM as 6KY.
Back then, it had a real adult music format, bordering on easy listening.
Hereās one from PMFM (now hit92.9) at around the same time.
Converted from AM as 6PM in December 1990, it had a more modern music format, somewhat softer than 96fm, who were still dominating the ratings at the time.
Both KY & PM were competing with each other until Jack Bendat, who owned the former station, bought the latter station from Kerry Packer in 1993. Bendat then sold both stations to Austereo in September 1997, forcing them to sell off Triple M (what 96fm had become by that point) to Southern Cross Broadcasting, who rebranded it back to 96fm.
Doing a bit of a YouTube deep dive and stumbled onto this.
Why were the actors in radio TVCs in the 80s and 90s all so insufferable?
2WS in Sydney had a similar ad when they converted to FM.
And so did 2CA in Canberra.
Thanks to Marc McCreadie for the above uploads.
I donāt know if there were any DAB trials on in Brisbane back in 2007, but itās to my understanding that DAB (as opposed to DAB+) was trialled in Sydney for quite a long time:

This YouTube upload is from June 2008 (so probably towards the end, before the DAB+ services weāre all too familiar with now started in August 2009), but the video description suggests that they were running as early as December 2003!
There were lengthy trials in Sydney, with both original flavour DAB and even L-band at one stage. The former were on air right up until the DAB+ launch. Iām not sure how early they started as I only got a capable radio just before the official start up date for DAB+.
I also remember the DRM trials on 1386; these were in 2005-2006 iirc. You could hear the digital hash on a normal receiver.
Hereās something for @Laoma & @dxnerd.
From the Radio Vault, an aircheck of 2CA from February 2001 recorded on AM Stereo, when it positioned themselves as an oldies station.
At the time, it was 100% owned by Capital Radio Network, before they sold 50% of it to Grant Broadcasters in 2004.
Thanks; I did see that as Iām subscribed to TRV on YouTube.
Thereās also this one recorded by dxer22000:
Was there any indication at the time as to why half of 2CA (and 2CC) was sold off? Not profitable as an AM duo against an FM duo?
Hereās the Radioinfo article from that time: https://radioinfo.com.au/news/grant-broadcasters-buys-kevin-blytons-stations
Hereās a 15 minute history of time pips. If you want a good nightās sleep, try switching this on just before bedtime, itāll send you to sleep:
When was 2ue last a full time music station? Was it the 70s? Or were there periods in the early 80s? I only remember radio from about circa 1982 or so onwards and I think it was talk by then. Without giving away my age, I was pretty young there even though I enjoyed radio, I may have missed it. Listen to 2uw back then and Mum mostly listened to 2day FM.
I think someone mentioned a brief foray into music in the late 80s. Iām too young to remember that, though.
2UEās brief foray into music happened in 1986. Hereās an article on SMH The Guide from February 1986.
In the first ratings survey of 1986, 2UE had an 8.4% share, but slipped to 6.9% the following survey & stayed in the high 6ās for the rest of the year before falling to 4.7% in the first survey of 1987.
2GB dominated in the ratings back then, thanks to Mike Carlton on breakfast & John Laws on mornings. Laws would be lured back to 2UE in 1988, which turned the stationās fortunes around for many years to come.
Thanks @TV-Expert as always. I canāt remember. I wish there was mediaspy back in the day. Did they stick music until 1988?
The 6PMFM branding lasted about 6 months in 1991 before becoming just PMFM
In 1998 Southern Cross Broadcasting owned 6PR and 6IX and sold IX to Capital/Grant to buy 96FM.
Youāre welcome. 
No. Not long after that, the ill-fated CBC experiment was happening, which saw programming between 2UE & 3AK outside of breakfast being shared across both stations. That was when 2UEās ratings fell to the high 6ās.
As always, @TV-Expert delivers! Thanks. If it was in February 1986 then that was definitely before my time.
2UEās slogan when it played music in the 80s was āAll Time Hits, All The Timeā
Quite catchy.
Correction - All Time Greats, All The Time
