Re: [Discuss-gnuradio] Unable to save demodulated data in file..

Hi Salman,

awesome application! As a hint for the future: GRC has a very handy "screenshot" function that just saves an image of your flowgraph as PNG (easier than taking a screenshot of your whole desktop). It's what happens when you use File->Screen Capture or click on the "Printer" button :)

To your question:
The files sink correctly saves your numbers to a file -- but that's not going to be a text file, but a binary file:

Hello every one,

I am trying to build a transmitter and receiver for satellite application based on dual modulation technique (PM/BPSK).  I have used discrete blocks for BPSK modulation and quadrature demodulator and PLL for BPSK demodulation as shown in Figure 1. Initially square wave generator is used as data source of "1010" which was successfully demodulated as shown in Figure 2 and 3. 

But when I tried to save the demodulated "1010" bits in byte form in a file , it resulted in unrecognizable data as shown in Figure 4. 

My question is: Why I am not able to save the data "1010" in file??

Kindly guide me through the solution..??

Best regards 

Salman
