[Discuss-gnuradio] Wrong ideal points on USRP1(gnuradio 3.2 rev.11223)? results form IQ const. plotting.

[tom_unaff]

Hello,
I do IQ plotting for DBPSK, DQPSK, 8PSK. (Please have a look below):

For DBPSK:
http://omploader.org/vMm16Zg/dbpsk_IQ_plotting.png
For QPSK:
http://omploader.org/vMm16Zw/dqpsk_IQ_plotting.png

Can someone explain why for DQPSK positions of ideal points are wrong?  It
should be [1,1], [-1,1],[-1,-1],[1,-1]

Also for DBPSK, Why symbols on right site (of Y-axis ) are far away from
point, [1,0]? How to fix it? 
Regards,
Tom
