[Discuss-gnuradio] tx_sampless.cc not working fine...????

[Krishna S]

Hi,
 
  I have some issue with tx_samples.cc and the GRC.
  
 when i send the file containing complex I&Q samples from GRC
Transmitter side : File Source --->USRP2_sink(interp=16, f=1.8G)
                                             |-->FFT_sink(avg=yes)
                                            
Receiver side:  usrp2_fftsink.py (decim=16,f=1.8G)

I get perfect frequency plot matching exactly as seen in the transmitter side.

But when i use tx_samples.cc (interp=16, f=1.8G, -r)  to transmit the same file. I get the almost same frequency plot with lot of dissortion, I have checked all the available parameters in the tx_samples.cc but in vain.

I have also , python generated code top_block.py by the GRC for the above function with the tx_samples.cc , both are sending 32bit floating complex values to usrp2_sink..., how come their results are different....? even though keeping all the parameters same for both of them...!
