[Discuss-gnuradio] Question about Basic TX/RX boards, the I, Q

[hanwen]

Hi, all.

 

Today I try an old QPSK transmission program on Basic TX/RX and failed. However, it does work well on rfx2400.

I just simply connect TX 1 of Basic TX on transmitter to RX 1 of Basic RX on receiver. The receiver program failed to synchronize with pilot sequence.

The carrier frequency is 100Mhz.

Is the signal from TX 1 is just I or Q path of the complex signal? I saw signal come out from both TX1 and TX2.

BTW, I could only receive signal from RX1 of Basic RX and nothing from RX2.

Very confusing. ^_^
