This product is Visio Circuit Schematic Symbols with the Amateur Radio Relay officially affiliated with the Amateur Radio Relay League
As a service to the many Amateur Radio Operators in the RF Cafe visitor realm, I spent many hours re-creating the set of circuit schematic symbols that are presented. They were built on the Visio grid to accuracy and scalability. I did not load them into a standard Visio stencil format because it is probably easier to just open the page and copy/paste onto your schematic. That way everything is in plain sight, rather than being buried in a long list of icons.
