Graphical Representation of Dial Tone

Starting Using GNU Radio Companion

Usage Tips

• Add a block: double click on a block in the block selection window.
• Connect blocks: click on the port of one block, then click on the port of another block.
• Remove a connection: click on the connection, press delete, or drag the connection to remove.
• Edit block parameters: double click on a block in the flow graph.
• Select a block, hit up/down for quick type change.
• For more short cuts, see the hot keys in the menu.
• Flow graphs that are completely simulation (without audio or usrp blocks) will consume 100% CPU when executed, and the GUI elements will be unresponsive. These flow graphs must include a Misc->Throttle block to throttle the rate of the streaming data.
