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?
