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.
