Re: [Discuss-gnuradio] offset at input of LF_RX

[ematlis]

gnuradio.org appears to be down.  Where can I find that flag, and how do I 
disable it?

However, my surmise of the last post seems to be correct.  When I 
substitute a regular Basic RX for the LF RX unit, the upwards shift goes 
away.  This is I'm guessing because, as I hinted to in my previous post, 
the the LF-RX is dc-coupled to the input signal, and because the USRP 
board is single supply no negative voltages can be represented.  The Basic 
RX, however, is AC-coupled through an input tranformer and as such any dc 
bias is automatically removed.  At least, that's my theory.

Any takers care to correct me on that one?
thanks all.
