Hi Maitry - okay, then Marcus has already updated you - DPSK Mod is
depreciated.
That is, it has bugs which can't or won't be fixed and is no longer
supported.

Hello,
I understand that I have use online ASCII to binary
converter and for that I am using below online converter.
But I am facing an issue, while I am transmitting
repetitive pattern such as 1100, 1010 , the data stored in the
file after mod-demod is almost similar( only some initial bits
are changed) . Please check the screenshot attached.
But when I am transmitting some random pattern instead of
repetitive using file source, I am not receiving the same
pattern, while I am converting the stored ASCII to binary
using converter.
I have sent the GRC file in previous mail. Kindly let me
know, where is the problem?
Waiting for your positive response.
Hi Maitry - if by update you
mean dumping a binary file as binary instead of hexadecimal,
then on Linux use
xxd -b <infile> <outfile>

Hello experts,
Any updates?
Ok, thanks.
Hello,
Please ignore the previous grc file. please
find attached the correct grc file.
Hello,
Please find attached grc file for
reference. I have done trial and error by
converting the output file into online
ascii to binary converter, but it provides
random output.
Please guide which binary viewer I need
to use in check the data in 1 and 0
format(binary) ?
Or maybe use a gr-baz any
sink to view bits?
Hello
Maitry,
The File Sink is not producing a text
file, it is the raw binary data.
You need to look at the contents of
the file using a binary viewer.
Regards,
Derek
