[Discuss-gnuradio] Re: USRP2 transmitter spectrum measurements

[Jamin Chan]

has anybody else experienced this problem?  I am working on receiving an 
RF signal, performing processing on the data, and then retransmitting 
it, using a pair of RFX400s.  On the TX side, I always get this big 
carrier spike, even with no input to the RX side.  Ive tried just 
straight feeding the RX to the TX, same problem.  Sometimes if I stop 
and restart the program, the spike disappears.

I have noticed a slight DC offset on the RX data.. Ive tried saving the 
RX data to hard drive and removing the offset in Labview, then 
transmitting the new data, but the spike is still there

I can post spec-analyzer screenshots if needed
