Yesterday I decoded a Chinese station on 30m WSPR, at a level of -28. From
http://wsprnet.org/drupal/wsprnet/spots:
2014-09-02 21:34  BZ1UIF  10.140268  -28  0  ND81  5  W0BTU  EM37  17566
 158

According to something you said in your interface PDF, the -28 seems to
indicate that I already have a decent sound card (among other things.) What
do you think?
