Re: More Chinese AM radio kits
If you are getting hiss from the speaker and are able to change the volume, it means your AF stages should be fine. Does your radio beat against another one nearby ?
I have had to make modifications to the PCB and add a couple of components to make mine work properly. The first one I made went dead due to blown preamp/ output transistors as a result of excessive current in the AF stages. This is due to defective circuit design.
I will attempt to post some photos of my mods and current consumption readings later today.
