Luca IW2NDH has done it again! First he developed an app for PSK31 and now after one month of hard coding and debugging work also an app for RTTY. The app is called IRTTY and I just tested receiving on 14.080 MHz with my iPod Touch´s external microphone placed near a Yaesu FT-857D transceiver. See screen dump above. Read here about IRTTY, which also can be used for transmitting RTTY. Here is a short video showing my receive test.
