So somewhere in the middle of nowhere or without Wi-Fi or radio or something?
Can you just turn it on anywhere and it works?
Apart from batteries as a power source, which of course it should have.
Or what does a digital radio need to broadcast?

Just something to tinker with and repair broken things to satisfy my electronics heart and not just at school.
As a child, I had long wondered what it was. I didn't dare ask my father because I didn't want him to know that I had looked at his stuff. Now I found it while cleaning and hope for your help. The two pins are each slotted lengthwise. The pin can be moved via a…
I would like to create my own search engine for learning purposes. How does it work? Are there official modules?
Digital radio works just like non-digital radio. And as you have not been able to receive any transmitter well anywhere, you can’t do that in the future.
It has nothing to do with Wi-Fi. Not with mobile. There are only the radio stations. The digital radio only receives.
Then why digital? Why do they want to change UKW or something?
You need lower bandwidths and can radiate more transmitters simultaneously.
Because of quality at UKW you always have disturbances etc because stop analogue signal. At the digital you have either crystal clear reception or even no one.
Without radio reception, a digital radio can not receive anything, so if you are somewhere in Brasielein in the deepest Dshungel, there is nothing with reception.
Then you have to distinguish between DAB+ what about the conventional radio frequencies or TV frequencies work
and
InternetRadio what works via an Internet connection, for example via W-Lan.
With DAB+ you only receive country-typical or local channels and is also only spread within Europe and Australia. However, if you plan to use your DAB+ radio on holiday in Spain, you will not receive German stations but only the Spanish stations. What you can see here in Germany:

With InternetRadio you can receive the transmitters worldwide (if the transmitters are not blocked by IP geoblocking), the only requirement is that you have internet access.
Unlike analogue radios, there is no noise that can be audible “receive” but digital radios always require a transmitter search and only the stations found can be set.
Why switch from analog VHF to DAB+? The reason is digital is cheap. Each individual FM transmitter requires a bandwidth of 300 kHz, the individual channels having a distance of 100 kHz. Thus, a maximum of 68 transmitters can be transmitted theoretically (at 87.5MHz-108MHz) to the UKW band (this would only be possible with cable connection; in the case of terrestrial radiation, this is clearly reduced because the transmitter regions overlap). With DAB+, on the other hand, up to 17 transmitters are transmitted on a single channel and this at a bandwidth of only 1.75 MHz. As a result of the smaller number of transmitters, energy is significantly saved and frequency band width is necessitated by the digital combination of the transmitters to a channel.
The frequencies will then be used for other services in the future so that, for example, other frequencies for the mobile radio will also be released again in order to achieve higher data rates.
…and suffers, to put it mildly, a "tremendous" loss of sound quality due to audio compression (in order to accommodate as many stations as possible in a digital package). This is particularly noticeable with classical music , compared to basic analog FM radio.
Digital reach: According to our own tests
(sorry that for decades I have been walking around with ONLY a few radio licenses)
by AT LEAST 50% (more realistically 70% and more) in range loss compared to current analogue radio.
Noise-free DAB reception: TRUE!
Because even minor DAB reception issues can cause the ENTIRE signal to crash. This results in severe dropouts and "silent images." The tolerance limit for this is virtually zero for virtually all current digital radio systems (GSM, Tetra, DMR, DAB+, etc.)!
This also completely solves the "noisy reception problem" .
In order to achieve the same ranges for DAB+ as with analogue FM radio, more filler transmitters are needed than with analogue FM radio in order to compensate for the range deficiencies to some extent.
In plain language, this means that more DAB filler transmitters are needed for ACTUAL , comprehensive coverage, and ultimately require just as much energy (if not more) than ONE FM analogue transmitter.
Whether this is actually cheaper than the current analogue FM radio system is something I, at least, seriously doubt. Physics ca n't be outsmarted, even by DAB lobbyists from politics and business.
Conclusion: DAB broadcasting is not a real gain despite the state propaganda we hear/see a lot from ARD/ZDF etc.
According to our own observations , over 95% of the receivable DAB stations (private and public alike) are soulless music steamers between Flensburg and Garmisch-Partenkirchen.
The rest of the reasons can be found in the lines above (even if these DAB+ lobbyists from politics and business do not fit into their agenda).
I don’t know why you all possible in fat have to blow out what you feel as disadvantages.
Yes, with the possibly lower or narrower audio quality, which could be audible in classical music, is a possible disadvantage. However, most transmitters do not have a real problem when mostly pop, rock and speech are transmitted. Classic is a special case.
That the signal in the case of reception problems coincides quite quickly. However, that one would need significantly more fillers, I consider a rumor. Of course, DAB+ sends on a higher frequency and is thus easier to shave off than with UKW, but the main problem is also the low transmitter strength at UKW, for example, with us from the Bungsberg 4 transmitters with 50kW power each, while from the same location two DAB+ transmitters are only sent with 5kW or respectively 2kW. The loss of range therefore comes not only from the higher frequencies, but from a simultaneous reduction of the transmission power. If you send out the DAB+ transmitters with 50kW power there would be a completely different picture.
The 95% of the transmitters should be soulless music steamers, which could be true for your personal taste. More selection does not mean that there are more stations that you would like to hear. Also at UKW I have only 4 stations I may have. I don’t care about the rest. But that’s fenauso on TV, you have your 4-6 channels that you turn on and the rest doesn’t matter.
I also did not claim the DAB+ or the digital reception is good, but only merciless cheap.
Blow out in fat :
Have you ever heard/read that if you "blot out" relevant bullet points in bold, this not only highlights their respective importance or focus, but also makes the entire article easier to read?
Personal musical taste
This is irrelevant here. In fact, almost all music streaming services play the same crap, sometimes even the same track at the same time. Anyone who doubts this should use the scan function on their radio to find out for themselves.
Excessive audio compression can even have a negative impact on pop music if the songs were recorded/produced with a higher audio quality.
Examples include Enya with "Orinoco Flow." The dynamic differences between listening to DAB+ and a regular CD or vinyl LP on a good system speak volumes. Even analog FM radio has more dynamic range than DAB+.
More filler stations needed and your opinion "this would be a rumor":
Technically WRONG!
You yourself admit that the higher DAB frequency range has shorter ranges than FM analogue radio. This is physically INDEPENDENT of any transmission power.
. All previous digital radio systems (DAB+, Tetra, GSM, Motobro, DMR, etc.) require better reception field strength across the board , REGARDLESS of their respective frequency range.
Digital only knows TWO states: Works or doesn't work (where "doesn't work" occurs more often than "works")
Because of these two points alone, DAB+ requires more filler transmitters than FM analogue basic radio.
So much for that. The potential renewed fuss about "blowing out the fat" is YOUR problem.
A digital radio has to receive something like any other radio. It doesn’t have to send.
To transmit language or music or data without cable connection, radio is used with electromagnetic waves (which is like light, only swing the waves slower).
Radio waves aren’t enough, they also have to impress the language or music or….
In light, you could do that by sending out more, times less light. So you can send a message to others slowly.
More or less light means amplitude modulation. However, it is also possible to use light-on and light-off and to communicate somewhat with the number of changes and/or the distances between light-on and light-off from the receiver. One or another, these are 2 states and 2 also stands for digit, i.e. digital.
What goes with light also goes hidden with radio waves (radio waves) but for the human being.
It must first be noted that where no radio waves arrive no radio, no matter how the waves are modulated, works.
Digital has a great advantage, you only have to distinguish between one and the other, but not between something, something more, more… This can be reinforced much better. It can be that a digital transmitter has a greater range.
But it won’t be enough until the “Pampa”. In addition, radio waves such as light cannot light around the corner, which only spread straight, so there are also radio shadows.
First of all, a digital radio NOT sends. It is a pure receiver for digital broadcasting programs.
Secondly, a digital radio IMMER receives via radio – but it has nothing to do with WLAN.
And since it works by radio, it is theoretically possible to receive broadcasts in the Pampa – if there is a transmitter nearby! Because it just depends on what you can receive where.
A digital radio does not send, it receives.
Weak answer from an expert.
You could have given me a really great, helpful, understandable answer, right?
I don’t know how much I know now.
You could have informed yourself on the Internet with the help of Google and a search, the information you want is freely available, for example, you could have read the DAB+ article on Wikipedia. You should really complain NIE about answers if you don’t know yourself and also don’t want to find and read the information yourself.
It’s all voluntary.
No one is forced to read or answer = weak response from an expert.
You should answer gf NIE if you don’t really like it or do not respond to the actual question so that answers remain helpful.
It’s basically not because it doesn’t have legs. It can also not send it, but only receive it. And this in turn only where a corresponding signal is sent.
That’s why I asked if it worked. 😉
Okay, you’re right about sending. 😉 But then it sends me sounds, I thought. And does a radio have a transmitter?
Well, hair split table… but not helpful for me… I’m not much smarter than before…
You can change that. In short, The digital radio can only receive something if it is located in the transmission area of a DAB transmitter. So everything is simple and logical.
I know enough to put on highways where no DAB reception works
Okay.
But my question only answers that a little bit, right?
You wanted to know if there are gaps in the DAB supply and that’s exactly what you got answered
Oh, that’s what I asked?
At scheena viadn Apfend no füa di!
as with any other radio alsoif you have reception it is
