Plug in Transmitter Adaptor for German Spies.
Hi
I've made a "plug in transmitter". It works really well, only I do not know the likely wireless it would be plugged into. It needs to be a EL91 or 6AQ5 and it needs to have SW on it. or maybe not. I've made a power supply for it, but what would it be like actually plugged into a domestic wireless!. Pete |

Re: Plug in transmitter spy

Re: Plug in transmitter spy
Hi Ed.
Yes I can do that. This is in two parts really, so I'll publish the first article as I think is basically the same as the project I've published. This was sent to me by a mate in Germany. I think that is published in the public domain. The radio is the forerunner to the project on here. We shall see how it is received. Pete (I will fill in as questions arrive) |

Re: Plug in transmitter spy
This is the "Adapter radio" That I've also made. This one uses the Octal plug. Whereas the second uses the B7G plug. The audio monitor is taken from pin 1 (i think) hence the radio needs a SW on it.

Re: Plug in Transmitter Adaptor for German Spies.
This circuit reminds me of the Olga set which was used by the Norwegian resistance movement during WWII. The circuit for the MK 1 and MK 2 are on the internet.
