there's alot of information about single-IC radio ICs like ZN416e here.

If this is your first radio project, you might find it easier, and more interesting, to build a crystal or regenerative radio instead. The parts will be easier to find, and, especially with a regenerative receiver, the performance will be better.

Join this Yahoo group to find many simple radio designs.

ZN416 is basically a ZN414 with an extra audio output stage. You should be able to find ZN414 or the MK484, a more modern version.

Look in the Solid State Radio section of this site for more topics and info.

There are many circuits using ZN414 + LM386. Here is one:


The site above, mikroe.com has a whole book of simple receiver ideas including ZN416, ZN414, MK484, etc.

I built this version and it worked well with only the ferrite bar antenna.

Hi,here http://theradioboard.com/rb/viewtopic.php?t=3317 you have all the documentation about ZN414, 415 and 416 and their equivalents.Enjoy the diagrams and good luck at work!

Andrei

PS:wait until the diagrams appear.They are scanned and added on high resolution because if you want to maximise them not to have problems with pixel (resolution)

Thank you really. I found the thing i want there.

There is an equivalent circuit schematics for ZN416E with 8-pin which i really needed. There it shows how to make a ZN416E by using ZN414.

Here i add the schematics for others want to make this kind of thing in the future:

For ZN414 equivalent can use this schematics:

@XtalHWJ
Thank you too. Since i ve found the schematics about the ZN416E i want, there is no need to change my circuit. I just want to make my own diy ZN416E.

But i think i ve another question:


Can i use another thing instead of ferrite rod for the antenna? For example can i use any iron?
Thanks.

Not iron. Ferrite rods are made of particles of iron oxide and a binding agent, extruded and baked. The particles don't touch, though they are close together. An iron rod would have too much loss at radio frequencies. The iron molecules are side-by-side and the conductivity of the iron would act as a short circuit across the coil wound on it.

You could use an air-core loop antenna. Here are some examples built by Dave, who runs this forum.

Homer Davidson's book on building radio receivers has a lot of ZN414 and 416 plans.

May be out of print now, but should be available used.
