A homemade dummy load should be part of your station's equipment.  With this simple instrument, you can adjust your transmitter off-air without causing interference with other communications services. This dummy load from "the250rider" is ultra simple:  8, 100-ohm, 1/2 watt (5% tolerance) resistors hooked up in series-parallel and immersed in vegetable oil. The impedance of this dummy load is 49.8 ohms.

Here's an interesting idea for those of us who need a quick and simple RF dummy load for testing our transceivers. According to "the250rider", materials for this easy project include (8) 100-ohm-1/2 watt-5% tolerance resistors in a series-parallel circuit immersed in a small jar with vegetable oil acting as a heat absorber.  This might suffice for QRP operations or for any other project needing only small amounts of power.
