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. 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.

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 only selectivity in your circuit is one tuned circuit on the input. 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 Tdq1083 on weather you wanted the local oscillator above or below the received frequency.

Media New media New comments Search media. Here in Canada 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.

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. Click here to register now. Articles Top Articles Search resources.

The design in Fig 10 on page 8 of the data sheet is how it should be used as an AM only receiver. It is designed to be used as a superhet receiver which means that the selectivity is provided in the IF stages.

If you are in the US then I would think you could get a short wave radion for a similar price to tdz1083 price in the UK. I am not clear about your location. At higher received frequencies the image rejection would not be very good with a Khz IF frequency. To participate you need to register.

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.

I think it would be cheaper to buy a ready made short wave receiver.

Its spec’s also show horrible distortion and noise. 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 end tuning.
