Qtmm souncard modem decoding APRS data from the ISS

August 23, 2016July 11, 2011 by Alexandru Csete

Yesterday I successfully received APRS transmissions from the International Space Station on 145.825 MHz using my Yaesu FT-817 connected to my MacBook Pro via a Signalink audio interface and a USB sound adapter.

 

Watch video on YouTube.
