Bruce is right about that fact. Thanks. Square up the 10 Mhz. Diff the leading edge (It actually doesn't matter) maybe 2-5pf cap and 300 ohm R to ground. Feed this into a transistor that is in the bottom end of a one transistor oscillator. There are actually several ways to inject. Think of a totem pole of 2 transistors. Use google and do a search and you will see what I am talking about. There were some articles that the spread spectrum hams used that describe it.
