TDA1083 AM radio circuit schematic

Your profile shows your location as the United States but in another thread you say it is Egypt. Using cheap mobile phone to send an alarm Started by Western 16 minutes ago Replies: 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. This design is for a fixed frequency as it uses a crystal controlled local oscillator.

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.

Started by Silverboy Today at 7: If you are in the US then I would think you could get a short wave radion for a similar price to the price in the UK.

At higher received frequencies the image rejection would tdx1083 be very good with a Khz IF frequency. But they are simple. Its spec’s also show horrible distortion and noise. Mosfet drain current spike and input current spike in full bridge inverter.

The design in Fig 10 on page 8 of the data sheet is how it should be used as an AM only receiver. Welcome to our site! This is just a more detailed explanation of what all of the other replies have said. You would need would need to use a variable frequency local oscillator.

Started by chemelec Today at 4: Which 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. Started by sr Today at 5: 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.

Note that the ‘circuit’ you copied says it’s for MF and a crap performer at thataltering it for short wave will make it even worse. Where do you buy the obsolete radio ICs you are talking about? Do you have 50 or more local FM radio stations in Egypt?

To participate you need to register. The only selectivity in your circuit is one tuned circuit on the input. I am not clear about your location. The way you are using the TDA in post 1 is not the way it was designed to be used. Here in Canada a half-decent FM radio has many tuned LC circuits so that it can select only one local FM radio station tdda1083 the 50 or more local stations here.

MikeMIok i get the idea. By continuing to use this site, you are consenting tra1083 our use of cookies. 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.

Playstation 1 motherboard housing fell off, help! 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 tds1083, IF, and front end tuning. You must log in or register to reply here.
