Radio History

A few stations in SE Queensland and Northern NSW used two or three digit frequencies. Others included Stereo 10 (1008 KHz), Radio 97 (972 KHz), and even 4GG’s (1197 KHz) jingle included “AM Stereo 120”.

2MW stopped using their callsign as their ID back in the 1970s (I think) when the Tweed region took over in prominence. “Easy Hits 97” as below for a while in the late 80s

Others I recall with rounded IDs

2ST Nowra - as “10 and 12 2ST” (999 at Nowra and 1215 Bowral)

2DU Dubbo - as “97 and 125 2DU” (972 at Cobar and 1251 Dubbo)

2WL Wollongong - as “Position 13 2WL” (or Stereo 13 as below)

2CS Coffs Harbour - used to ID as “Stereo 64 2CS”

And as you mentioned, 4GG Stereo 120 as below

Easy Listening 97:

2MW - 970 close down

When the frequency could be described with just one number (on your transistor).

Rhythm of the City 100 3DB in Melbourne. Seemed odd to do that just as FM was beginning and could cause confusion. Actual frequency 1026. Unless it was before 1978 when it was 1030. Can’t remember when the ROTC format began.

No it was in 1980 after they had moved to 1026. They probably used 100 3DB rather than 103 because dials on AM radio usually had 100 on them and 3DB was at the upper part of that 100 number on the dial.

4AY also used Rhythm of the City - the Rhythm of Townsville.

I believe there was also Radio 90 (2LT).

I’ve been looking for this…

2DU also used Rhythm of the City IIRC, their old website had some jingles when they celebrated a anniverary years ago.

Were some stations using the 10kHz spacing in their branding to sound American?

I think 3UZ kept using the slogan “The greater 3UZ 930” even after they moved to 927.

was probably more just for simplicity. Having the precise kHz numbers was not particularly necessary with manual radio dials where frequencies were marked in blocks of 100s, etc.

I don’t think so, it’s just that tuners weren’t digital and often had those numbers listed on them.
