QRP operation means transmitting at reduced power levels. Most amateur radio operators broadcast their signals with roughly 50 to 100 watts of power. However, in many cases, it is commonly found that this isn't necessary, and thus, not only wastes power, but is in fact a violation of FCC Part 97 rules which states, paraphrased, "One must use the minimum power which is required to establish and maintain a contact." Of course, this regulation is dreadfully hard to enforce, and indeed, for the most part, it really isn't that big of a problem.

Typical power "limits" for QRP depend on the mode with which you choose to work. For morse code (CW) operation, that limit is 5W. Now, if you're rig puts out 6W or something reasonably close to 5W, I'm sure it'll still be considered a QRP rig by many. For single sideband communications (SSB), that limit is 10W. Since so many other "modes" of operation ultimately are glorified SSB emissions (e.g., PSK31, AX.25 packet radio, etc.), it follows that these modes also share the 10W limitation.
