To participate you need to register. But they are simple. Where do you buy the obsolete radio ICs you are talking about?
If you are in the Tda0183 then I would think you could get a short wave radion for a similar price to the price in the UK. This design is for a fixed frequency as it uses a crystal controlled local oscillator.

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. Its spec’s also show horrible distortion and noise. It is designed to be used as a superhet receiver which means that the selectivity is provided in the IF stages.
Which will ttda1083 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.

Of course the TDA produces tsa1083 sound without much hiss or noise, it is FM, not AM and it cuts high audio frequencies to reduce its hiss.

At higher received frequencies the image rejection would not be very good with a Khz IF frequency. You can obviously make an AM only radio with that IC, but you still need all the Tea1083 parts to make it work – as it’s a superhet you need a local oscillator, IF, and front end tuning.
