4GG from 1967 - 1989 22 years and 4GGG etc for 28 years

I remember they started retransmissions in 2001, so therefore, theyâve been on air for around 16 years, which is now longer than when 2WS was on AM, which was a little over 14.5 years from November 1978 to June 1993.
Another thing about 2GO, it has the rare distinction of having broadcasted on FOUR different frequencies.
1310, 1323, 801 and 107.7.
I doubt any other commercial broadcaster has achieved that.
Wikipedia suggests that 3DB achieved this, first on 1180 AM then 1030 & 1026, settling on 101.1 FM as KIIS today

4BH would have notched up 4 frequencies by the early 70s.
1380 in the 1930s, 1390 up until the mid 70s, then to 880 then with the switch to 9kHz spacing 882.

Just thought of another few
3KZ 1350, 1180 1179 104.3
4TO 1170, 770, 774, 102.3
7HO 890. 860, 864, 101.7
2UW 1125, 1110, 1107, 106.5
I think also 2WL and 3GL
If 4BH had converted to FM that would have made 5 frequencies. Adding 102.9

I remember 4TO having the frequency as 780 AM not 770,this was about the mid 70s
Could BH have ever been on 102.9 ?
It wouldâve caused harmonic interference with ABQ-2, hence why itâs never been used in Brisbane.
What was the idea of 4TO being on 1170? What was around the 770 mark that prevented it beginning there? Why did it move to 770?
That was in the 1930s when first on air. At the time all stations below about 860 were higher power national stations. Class B commercial stations were low power in many cases on vastly different frequencies to the iconic ones most people remember.
I assume the move occurred around the restack to 10kHz spacing (it had been 5). Perhaps the lower frequency was less prone to topical storm lightning interference. (all guesswork)
That was the original frequency identified for the conversion but it was subject to 4DDB changing frequency. The other frequencies identified in planning for Brisbane were 94.9, 95.7, 96.5, 97.3 and 98.1.

Nothing to worry about, over all freqs, Al Kirton screams blue murder about âtropical interferenceâ from lightning and 4KZ is at AM 531.
4GR always around 864?
Could you please upload the document of this? Would be great to read a conversion document explanatory paper from that era.

4GR was on 1000KHz or was it 1000 Kcs at the time

Thanks for the URLs, had forgotten what a great source the journals are.
Good old Ted Gold, running 50 watts, what a pioneer, fantastic family.

Yes 4BH were originally allocated 96.5 but requested a frequency closer to the other three - 104.5, 105.3 and 106.9 (QFM).
The broadcasting authority were reluctant due to the potential interference you mentioned but eventually agreed they could use 102.9
Of course it didnât happen in the end.

I seem to recall when 97.3 was offered there was talk by some of not wanting a frequency âdown with the regionalsâ but look how that turned out.

Yeah I donât think it would have hurt 4BH to be on 96.5. In fact I think it might have been better for them there rather than sandwiched between 4ZZZ and 4MBS

Interesting read, thanks Cynic.
I picked up on the list of three AM frequencies in Melbourne that were âpreviously used by commercial AM radio services which converted to the FM bandâ - 1116 kHz is still occupied by 3AK, which was to convert under Alan Bondâs ownership but failed to come up with the money.
1422 kHz was never an FM conversion - the former 3XY later morphing into 3EE/The Breeze on 693 kHz (now a Greek language narrowcaster). 1593 kHz is Rete Italia now - was there a former service Iâve missed?
Of the two stations that did convert, 1179 kHz (then 3KZ) is now used by 3RPH/Vision Australia Radio, and 1026 kHz (then 3DB/3TT) is now 3PB/ABC News.
1593 used to be 3PB aka PNN AFAIK.

Note that 3AK moved to 1116kHz in the early 2000s (from memory) from 1503kHz where it had been. Now that original 3AK frequency is also in use by a community broadcaster
