if i have to make transistor radio...could you just please tell me where i have to put tank coil (emitter, base or collector) and where i have to put feedback coil??? is the areal wire you have shown with 4 turns, the same called feedback coil??? what is the function of feedback coil and where it is plased in transistor please help me...dont discuss amplifier, i want to know about the first circuit,amplification comes next stage...please help.
please tell us how to make an Transistor AM radio very simple...we dont want IC like MK484 or ZN??? because its not avalible in our country ...we have 5 simple NPN transistors 2N3904... how can we amplify radio signals to drive a small speaker...please make a ten minute project on that..thanks
Yes, excessive for what it does, but it's designed that if you replaced a few components with tunable varieties you would have a fully tunable radio. We didn't do that with this one, but the rest of the design gave us experience on how one would do that. As part of the project we did have some limitations in that we couldn't use ICs(except for audio out amp), BJTs being the only part allowed other than basic circuit components.
So, thats a single channel, one frequency - AM receiver at 550 khz? And all those things to do that? Wow...okay, different approach, excessive...but cool somehow, something new, haven't seen that.
Pls can u help me with the cicuit diagram u guys used for this project. Tanx

5 stars for originality. ;)
