Re: ZN414 and TA7642 radios
To those who have contributed images of their own creations: Jolly 7, Ian G4JQT and Samoca 58.
I am sure that we'd like to know more about them and see more images.
Here's that little kit I got. it seems to be of Thai origin. The instructions were written in Thai and English. I haven't tried it yet. Operating voltage is 3V & the o/p is into 32 ohm earphones or headphones.
I have another circuit I made on stripboard that I really ought to mount onto something.
It was a modification of an article out of 'Electronics Australia' that exerted more control over the ZN414. I will provide the link, when I find it again. My modification was to remove the audio stages. I am not sure whether to get one of those ready-made TBA820M circuits or feed it into a Mazda SP61, to see what output I get.
