Please help me. :-( > > Bye!! > You said that your recording is at 8MHz bandwidth (8Msps complex). Since 8Msps isn't a "proper" bandwidth for the USRP2, you'll have to up-sample to a proper (10MHz) rate before you send it to the USRP2, and select the appropriate interpolation ratio. You'd have to specify an interpolation value of 10.
