It worked perfectly; thanks! Ben

Only one thing may be connected to an input. You have to choose different input ports for the adder. Give the connect statement a tuple of the form (block, port_num). Like so... fg.connect(self.packet_transmitter1, self.chan_filt1, (self.adder, 0)) fg.connect(self.packet_transmitter2, self.chan_filt2, (self.adder, 1)) Hope this helps. -Josh Ben Olsen wrote: > Hello, > > I am having a problem in trying to add multiple complex filter outputs > using the gr_add_cc code, I think the solution might be pretty simple > but I'm not very experienced with GNURadio!
