Hi,

I have an IQ file sampled at 48kHz and want to transmit through gnu radio. The IQ samples are each 16bit, and stored interleaved in a file

ie, IQIQIQIQ... I 16 bit and Q 16bit

I tried creating a grc using iShort to Complex block and send to USRP sink block (usrp n210), but the signal received is distorted. Do I need to convert the short values into float -1.0 to +1.0 before transmission. Please help in resolving it.

I want to use it only through grc and not to use tx_samples_from_file which does the same.

You'll need to scale your samples into {-1.0,1.0}
