Auriel Receiver
This receiver built by Walter Krämbring uses an Auriel receiver card. Walter is somewhat more brutal regarding the connection to the microphone input than I am - he skips the capacitors altogether. Apparently the Auriel device can handle the DC level from the microphone.
The Circuit diagram is like this:
The receiver device used is made by Auriel an called RX-4M50RR30SF. It is available from many suppliers, but Walter recommends http://www.soselectronic.com, where the device costs 5.93 EUR (search for RX-4M50RR30SF).
