&gt; i have an USRP1 with DRX and RFX900 daughterboard and wanted to play a<br />&gt; bit with the basic tetra decoder.<br /><br />&gt; Which kind of daughterboard has been successfully tested with the<br />&gt; current osmocom tetra?<br /><br />I used the WBX to receive in the 400 MHz band.<br /><br />Both the RFX and DBSRX can&#39;t receive in that frequency ... <br />Maybe the TVRX / TVRX 2 could receive it as well but I didn&#39;t test.<br /><br /><br />Cheers,<br /><br />    Sylvain
