[Discuss-gnuradio] Success!

[John Ackermann N8UR]

I'm now listening to some awful music from an awful local station -- but
a strong one -- through the USRP Basic RX port.  So, things are working!

Just one problem -- when I try to use the TVRx board, I get an error
that apparently springs from tvrx.h  and a failure to define global name
"u".  The traceback is below.

Any ideas about how to fix this last problem?

Thanks -- and thanks for all the help today!

John

(Note: I changed "which_side" in the program to "1" because the board is
on RX B.)
