Forum: GNU Radio I could use guidance

Hello,

I created a noise source and a tcp sink (server).  I connect to it with
SDR# (on another machine) and get plenty of noise.  Next I created a 
signal
source of 1khz and add that to my noise source.  The unexpected result:
carriers all over the spectrum.  None of which are at 1khz.

You're probably having a good laugh.  You're welcome.

I'd like to modulate the amplitude of a carrier and drop that into a
randomly-generated noise floor. And I'd like to stream the whole thing 
to
sdr-software across the network.  Are my expectations too wild?  Is this
possible?

Thanks for your time,
Ashworth

WHat does the attached flow-graph produce for you?

My guess is that you have the amplitudes set so that they're saturating
whatever SDR# is doing with the I/Q signal from the TCP
   channel, or that it's a typing/endianness issue.
