But they are simple. You would need to use a two gang tuning capacitor so the input tuned circuit was tuned to either Khz above or below the local oscillator requency Depending on weather you wanted the local oscillator above or below the received frequency.
Media New media New comments Search media. Where do you buy the obsolete radio ICs you are ta1083 about? At higher received frequencies the image rejection would not be very good with a Khz IF frequency. But it was designed a long time ago with only a single tuned LC circuit when there were few FM radio stations to cause poor selectivity.
TDA AM radio circuit schematic
You would need would need to use a variable frequency local oscillator. You can obviously make an AM only radio with that IC, but you still need all the AM parts to make it work – as it’s a superhet you need a local oscillator, IF, and front tra1083 tuning. MikeMIok i get the idea.
TDA1083 AM radio circuit schematic
To participate you need to register. Of course the TDA produces clear sound without much hiss or noise, it is FM, not AM and it cuts high audio frequencies to reduce its hiss.

The way you are using the TDA in post 1 is not the way it was designed to be used.
Its spec’s also show horrible distortion and noise. Started by Silverboy Tda10833 at 7: How to create dashed plot in Octave?
This is just a more detailed explanation of what all of the other replies have said. Started by rashan shrestha Today at 9: The only selectivity in your circuit is one tuned circuit on the input.

Here in Tda10833 a half-decent FM radio has many tuned LC circuits so that it can select only one local FM radio station from the 50 or more local stations here.
It is designed to be used as a superhet receiver which means that the selectivity is provided in the IF stages. I think it would be cheaper to buy a ready made short wave receiver. Playstation 1 motherboard housing fell off, help!

Started by chemelec Today at 4: Tda11083 will have quite a low Q as it is loaded by the antenna and the input of the IF amplifier which you are using as an RF amplifier.

question about a radio circuit ?
An newer version is the TDA that is in a “radio” sold for one dollar at The Dollar Store and it also has terrible performance. Do you have 50 or more local FM radio stations in Egypt? This design is for a fixed frequency as it uses a crystal controlled local oscillator.
