I am glad that the thread finally came around to the same conclusion I asserted in post #4.

Yes, you are right, I can forgo the volume control in this circuit, let the amplifier do the job.

Thanks for your contribution.

And if you use an amp with no volume control, like one intended to connect to a computer or phone, wire a pot the way @MrChips showed.

 

Dear Sir,

I am a new comer in this forum, I wish that I am posting to the right thread. Please excuse me if I am not.

I am doing an electronic project on Air Band Radio Receiver, I got the circuit from the web as attached.

The shorcoming of this circuit is that the receiver does not have a volume control. I am not certain where should I insert a 10k potential meter for this purpose.

Can I replace R13 with a a 10K potential meter with the wiper connected to the collector of Q4 ?

If not kondly show me where should I insert the volume control in the circuit.

Also please let me know if there is any modification if needed.

Thank you in advance

Best Regards

Two best ways would be :either substituting the last collector resistor with a potentiometer, or put a control at the end after the cap.
