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? 73, Mike www.w0btu.com On Mon, Sep 1, 2014 at 2:38 PM, Jim Brown <j...@audiosystemsgroup.com> wrote: > Also, use a good A/D converter to get the RX audio into your computer. > Several good, inexpensive USB sound cards are listed on my website. > Switching from the mic input of my laptop to these units allowed me to > reliably decode signals 12 dB deeper into the noise on JT65. > > http://k9yc.com/USB_Interfaces.pdf > _________________ Topband Reflector Archives - http://www.contesting.com/_topband
