Omnia SDR test with WSPR

Last night i have try WSPR with my OmniaSDR, since i bouht this kit long time ago but did not success to test yet because don't have measurment. last night i manage to test by use second SDR receiver to get the signal from Omnia SDR and i found that frequency for Omnia SDR diff around +55Hz. this is impage to WSPR because it will sent out of band. So i manage to adjust and archive the target.

WSPR Signal after do some adjusted. so signal send in the band.


I used WSPR v.2.1.2  in this version i can config WSPR software to connect Omnia SDR directly by using CAT interface fith SI530 driver. you can see info as below.
