AM To FM Conversions

According to the ACMA report, Albury is a market slated for an AM to FM conversion.

Yeah, it was officially a s39 supplementary licence and they treated it as if they moved to FM because that was all the rage back then.

Same story for 4CA and 4MK in Maroonland

That’s what Trevor Sinclair does so well on his 2UE breakfast show. He knows the audience and Sydney well to air the information you mention.

You can listen on digital radio and it sounds great, rendering the AM/FM comparison irrelevant.

So their s39 didn’t begin as Hot FM?

Slightly different in Cairns and Mackay.
The s39 launched as Hot FM. 4CA and 4MK moved to FM when DMG purchased one of the two new FM licences in each market in about 1998/99.
In both markets RG Capital got the other new licence and launched Sea FM and AMI radio bought the AM licence.

Thank you, that was my recollection of it too

4AK & 4WK will be largely stranded on the AM band with same or less audience share than already.

Audiences select the best fidelity option, hence why the one commercial all FM station in the market has a disproportionately high share. Sure wouldn’t be for the irrelevant networked breakfast or same tired old playlist.

Radio may be a passive medium, yet audiences still want to hear the best audio quality possible.

Hopefully Bill and staff will submit their B92 forms soon and the spectrum can be allocated.

And that there are more FM radio receivers now than AM and that it can be hard to get good AM radio reception these days with so much electrical noise about.

And yet people are quite happy listening to 32k or 48k DAB+ or web streams of 56k mp3 & still have personal music libraries in 128k mp3 which they think sounds great. :man_shrugging:

When it comes to audio quality, I think it’s a perception thing more than actual reality.

DAB+, even at anaemic bitrates, is considered inherently ‘better’ than AM by virtue of being digital. This isn’t helped these days with the amount of RF garbage around on the AM band.

A well processed AM signal will sound light years better than a tinny 32kbps DAB+ stream, but most listeners will still gravitate towards the ‘digital’ signal as the ‘superior’ option, given the choice.

Particularly if it’s in AM stereo!

However most AM radios in use are very low bandwidth affairs that don’t take advantage of the full frequency range possible from a good signal.

Agreed and with modern DSP based radios it wouldn’t be hard to have it in modern receivers

Was actually listening to 4AK today via my SDR and had the bandwidth opened to 12khz of audio and it is amazing how good AM can sound with a strong signal and decent audio bandwidth

It’s really quite amazing how efficient AM can be, considering you probably need to get 200 khz or more of bandwidth to get good quality FM stereo.

Coming in back from Tamworth at the end of Easter and driving south of Mt sugarloaf I noticed how much better the Rhema site gets out to the south. Rhema and 2RPH are basically at equal strength right into the Central Coast. 2RPH is 4KW OD at 134m and Rhema Newcastle is 2KW DA and at 120m.

This could be a good option for 2HD for a potential FM conversion. It may allow them to secure cheaper site rental than at the main Mt Sugarloaf site. It will also allow them to keep their existing level of coverage which they currently have on AM into southern Lake Macquarie which they cannot get from the main Mt Sugarloaf site at 2KW.

The AM signal will be switched off at 2pm today (15th April 2024).

Do they own the land adjacent to the studios where the 2MG 1449 AM transmitter is?

Could be good land to sell and sub-divide now once the transmitter is switched off.

Trying to listen atm via Freemans Reach SDR but signal is incredibly weak. I don’t suppose anyone is recording this? They’re going through the whole history of the station.

They’ll go live on Facebook from 2:30pm AEST ahead of the final switch-off.
