How Digital Radio Works

You're making a huge impact. Your sacrifices don’t go unnoticed. 👍

terrific video

I've picked up a blue dongle to play around with. But i'm looking around to get a better antenna. I'm a bit clueless. How to capture a wider range of radio transmissions?

dont take this the wrong way - but you look more professional in a t-shirt rather than a wife-beater.

I can't even get digital radio on the Gold Coast. Even if the repeater is on Mount Tamborine.

Looking fresh, did you end up finishing the install of your water tank ultrasonic sensor? I’ve been referencing a few of your videos as I delve into the world of tech operations and I’ve found your content to be super useful/informative. Enjoyed this one, appreciate the upload my dude!

Who is this guy? What did you do with CWNE88?! lol

Is this the same as HD radio in the USA.?

What have they done with CWNE88?

In the UK radio stations have highly compressed audio,even even with AAC codec being used.
They seem ram in too many stations into a multiplex,which cause sound quality issues.
Your favourite stations appear and go from multiplex from time to time.
DAB is crap, there's more of varied selection in internet radio.
I don't think DAB will be here for long .

And do you have a license?

Tall Paul tech? How tall? +200cm?

I like the new channel name and the video was very informational

Radio is nearly dead, with all the streaming services and personal media.... Radio wont last long, death of FM will surely be the death of radio...
Except for those hardcore enthusiasts and hams.

why is it that every time you release a video it is about something i had just recently developed an interest in?

Satellite technology in deep would also be nice. Great video. Thanks.

Do you have your VK license? Great video, thanks!

Love your knowledge, love your content.

Hi from Sydney 👋, Can you use the RTL-SDR to record all the DAB+ stations at once? Ordered one, going to take till October for it to arrive.

Fantastic video & set of links

So how does digital radio work? I'm no wiser.

One of the few video's with an in-depth presentation on the DAB+.topic Thx!

there is actually 4 ensembles now 9A 9B 9C and now 9D

Great video mate!!!

Hi Paul, very interesting your video about DAB+ in Australia; and it is true that DAB makes a more efficient use of the spectrum than analogue FM; but ...
88 > 108 Mhz is a 20 Mhz bandwidth; if you set one FM TX each 400 Khz, then you have 20000 / 400 = 50 stations, approx (I am rounding numbers here);
first consideration: the 400 Khz separation is dictated by ACMA, not by a real technical rule or formula; in other parts of the world TX licenses in ana FM are issues even wit has low as 50 Khz separation; and trust me, you can tune each one of them no problem; yes, you would need better quality (i.e. higher selectivity) receivers, but then what the ACMA is saying is that b'cause in Australia crap FM RXs are allowed to be sold, then the minimum separation can't be any lower than 400 Khz?
Anyway, lets' stay with the 50 stations inside a 20 Mhz bandwidth;
Let's focus now on another digital modulation: DRM30; DRM 30 has been designed and advertised as the way to digitise AM and SW; I have carried out few experiments and found (with my own eyes and ears) that stereo audio, better than FM and almost CD quality, can be transmitted using just 20khz of bandwidth using the OPUS audio encoder with DRM30;
during my experiments I have also found that it is absolutely irrelevant the actual frequency used to transmit the data stream; I have even very successfully transmitted the DRM30 data stream via internet, sending it to an ICEcast server, then tuning into it from another PC / another location and feeding the data stream received to a DRM decoder via a virtual audio cable; with beyond impressive results; SNR >60 dB!!!;
so, I don't know over east ( I am in Perth) but here nobody listens to DAB; everybody goes with conventional FM for convenience or with web radio streaming; simply because almost everybody has an FM radio already and definitively everybody has already a smartphone with internet access, so why would anyone want to spend $ 50 por more for a decent DAB radio?
RAdio is not the same as TV; TV was successful in moving from ana to didgi because one can actually SEE the difference; HD, UHD, just are not possible with analogue TV;
but with radio, FM quality is enough for the vast majority of listeners; a good FM station already provides interference free reception; and if they will one day stop TXing in analogue, people will simply switch to internet streaming, not DAB.
DRM30 used on FM band 88 - 108 has, in my opinion, a change; because it takes much less bandwidth than ana FM and becausesmall adaprtos might be marketed to adapt already existing FM radios to receive digital DRM30.
Think about this: why do you think CRA ha snot abandoned FM analogue just as yet? Why do you think HPONs and LPONs still can fetch many thousands if not tens of thousands of dollars at auction, if they are allegedly a thing of the past?

They shoveled so many low effort music stations in there. If they only play music like the background of a supermarket, they can download the music easily and just play it without a radio.

32 kbit/s in the 21st century is a disgrace. Nobody would have music files any less than 192 today. At good quality you can fit more stations.

Count the money that it cost them to put up the new super expensive computerized transmitters. And the kickbacks they received from manufacturers.

well this goes way over my head i quit , i just want to know why DAB needs an 80's analogue aerial? and reception usually crap

Great summary, awesome. Thanks mate! 🫶

DAB might work in Australia, but its not worth a bugger in the UK!

So DAB will still be broadcasted over antennas?
That's idiotic, instead of reducing RF pollution, we're increasing it!

very well explained and interesting video
