[Discuss-gnuradio] RFX2400, really noisy signal


From: Albert Rodriguez
Subject: [Discuss-gnuradio] RFX2400, really noisy signal
Date: Fri, 25 May 2007 11:45:27 +0200

Has anyone achieved a good received signal with RFX2400? When I worked
without it , I had signals that went form 4000 to -4000. Now I'm using
the deinterleave and the received signal is really noisy when I see it
with the scope, and can't achieve up to -40 to 40 amplitude in the
scope. How's that?
I'd really appreciate any kind of help 'cause I can't understand
what's happening

        src.set_nchannels(2)
