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.

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.

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.

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!
