Videos of iPhone Box DC Receiver
These are just a couple of short videos that I made for my nephew before sending him this receiver.
As you can hear, deafness is not a problem with this design! I did make some frequency stability improvements after this video was made -- I think you can hear a bit of drift. Still, not bad for a very simple circuit using a polyvaricon superglued to the back of a cardboard box.
I'll post more videos of the second version of this receiver. There are further improvements in frequency stability. My goal: "Juliano Si5351" levels of stable-ness.

Gold stuff Bill. Thanks for sharing the details.
ReplyDeleteThis will be my first scratch build. I have studying the schematic and hope to noodle the layout this weekend.
My first component order should be here soon. I am excited and scared. But you can't learn to be good without making an effort and stumbling as ya go.
