774 ABC Melbourne audio problem

(1/4) > >>

Circlotron:
Could others in Melbourne have a listen to the above station on AM, not on streaming, and see if they can hear a problem with the audio? To me it sounds a bit furry or fuzzy similar to crossover distortion in an audio power amplifier, or that fuzziness you get with 8-bit audio. It is not huge, only slight. It is most apparent with voice. I sent them a text message the other day but I got no reply. I don’t think it’s my radio because other AM stations sound okay. If there are enough positive responses I’ll send them a link to this thread.

Edit-> it seems more pronounced when someone is talking from the studio and not when from an external audio source e.g. when someone phones in.

Whales:
In Sydney, sorry.  Not that I have not had my own recent AM reception problems.

Daft question: tried with a different radio?  If not, then tried changing the batteries?

VK3DRB:
Who listens to AM these days?

DAB+ is far, FAR superior in sound quality and I know 774 is on DAB+ as well as the Internet. Have you tried listening to it on the car radio? That would verify whether it is your radio or a transmitter problem.

Appropriate lyrics from this classic :) ...

In Rome,
but to my ears the channel sounds quite good for AM.

I think I can still hear the problem on that receiver, but I'll have a listen on the car radio tomorrow.
