When did Australian AM stations go to 9KHz channel spacings?

Noticed they have the move to 1251Khz occurring in 1960.
I thought the change to the 9KHz spacing for Australian AM stations occurred
much later.

Thank you. I thought it was a bit later than 1960. I remember the
change-over, just can't recall whether I was working at 3SH or 2QN at the
time.

It was so we could get more stations into the available frequency spectrum.

They were both ABC-operated "experimental" stations.
The Sydney-based 2JJ was the forerunner of the JJJ network. It launched on
the 19th of January, 1975, before moving to FM as 2JJJ on the 1st of August,
1980. The JJJ network began in 1989. JJ used to boom into Devonport,
Tasmania, at night, so reliably that one local coffee shop would use it as
their background music for the customers.
In Melbourne, 3ZZ, was set up as a "community access" station - it didn't
last, sadly, but showed the powers-that-were(?) that there was a role to be
played by community radio.

That's interesting: I used to listen to 2JJ in Toowoomba in the late '70s.
It used to fade out a bit, but Glenn A. Baker's "Rock 'n' Roll Trivia Show"
on Sunday nights was just the greatest "oldies" show ever.

radio comms must abide by this bodies wishes. It is made up of reps from all
countries and is needed as radiowaves go everywhere, with no respect for
man's territorial boundaries.
The change was made to avoid as much as possible the night time interference
between Europe and the US. You must remember are only across a small ocean
from each other!!!
It also gives Europe more channels than the US and this is why the US band
goes to 1710 khz.
Any way that is what I understand does any one have nore to add???

I worked at a station that moved down the dial quite a bit and on the close
of the night before the change (11 pm close time) had to explain to the
listeners that they would have to retune to a new part of the dial to pick
up
the station, they did run a tape on the old frequency for a few days telling
people where to find the new frequency. (bit like when 3ak moved a few years
ago)
Station was 2RG moved from 1070 to 963.
As to the spacing i would have liked to stay with 10kc but most of Asia had
gone to
9Kc so those in remote areas in the north of the country had to put up with
a mess.
I traveled in Nth Aust before the change over and the dial was full of
hetrodynes and
stations on top of each other, quite interesting,

rest to the
Americas and of cource they are not metric either.
There are so many stations in Europe and America that i think is not to
common for one to hear hetrodynes from across the pond.
Even without the international regs Aus had to change due to the
Asan situation with Thousands of stations close by messing up our band.

I was thinking that but even I wasn't going to post it!!!
For me "I" hate JJJ with a passion!!! A total waste of spectrum in my
opinion. Youth station my butt!! Constainlty out rated in that demo by all
commecrials on a market to market basis!
Now don't get up me peoples!!! I believe the early days of it (before going
national) was the best! It had FOCUS in those times! It was a TRUE
ALTERNATIVE music station!! We used to get it on the Gold Coast via 4SO
on1593 over night. 4SO went to Coast FM 91.7 an easy format when it coverted
to FM.
About mid to early 90's JJJ came on it's own FMer here after ages of fringe
Brissy recption.
So yes what were they smoking in that cafe????
Peter Tate
True about the different spacings on the opp sides of the pond. I'm not sure
of the exact reasons for all of it.
The pint about there being heaps of stations in those areas would be correct
so with all the mess from withing the country, why bother about stuff from
afar?
Yeh!
Fair enough!

It wasn't necessarily what they were smoking .. it was the alternatives they
were faced with -
play music cassettes through the backgound system (remember, there were no
CDs yet); or plug the radio tuner in - NOT to play 7AD (my heavens, it was
woeful at that time ... either racing coverage - dogs and/or the trots ..
and their music playlist was equally bad: every third track had to be an
instrumental); 7BU might have been alright, but had lots of ads, as did 7LA
and 7EX in Launceston. So the ability to pick up 2JJ was a bonus.

It never sounded too way-out to me, but I was in my 20s then! (Glenn A.
Baker was anything but!!!)
It was playing what I guess was "new wave" at that time, good pop/rock maybe
away from the mainstream. I do remember (for some reason) hearing the
Saints' "Know Your Product" for the first time on JJ. They had some
well-informed presenters: I'm trying hard to remember who (they obviously
made a big impression on me!) Chris Winter?
Glenn A. Baker's "Rock 'n' Roll Trivia Show" ended up going for 3 or 4 hours
on Sunday nights. He played lesser-known tracks from the 60s & 50s, used to
have record collectors in as guests, but he also included the current new
wave/power pop bands that would fit in to that sort of sensibility. He was
pretty big on Dave Edmunds, that kind of thing.
