 ====== Auriel Transceiver ======
-This transceiver (combined transmitter and receiver) built by Walter Krämbring uses an Auriel devices for transmission and reception. This device packs a bit more power than the other, as he uses a voltage converter to get 12V to power the transmitter. As in his transmitter, Walter skips the op-amp entirely in his design and uses a single transistor to amplify the audio signal. I am not sure that I understand how this connection actually works. I have a suspicion that is is dependent on the characteristics of the USB sound card he is using, so I recommend some experimenting with this circuit before you commit it to soldering.
