![]() ![]() ![]() It's not as easy when the recommended range on the ALC meter is wide. The Elecraft K3, Flex Radios, and Yaesu FT DX-3000D are good examples. The key is knowing how to use the ALC meter.Ĭhoosing an optimum amount of ALC activity is easy if the radio manufacturer tells you the ideal ALC meter reading. This article is about how to operate a transmitter at the optimum point-where the average signal level is as high as possible without noticeable distortion or interference. It keeps the amplifier input in the designed range for linear operation.ĭepending on the ALC circuit design and how hard it is driven (by the microphone output level and mic gain setting), the ALC circuit can distort the signal and cause interference. An Automatic Level Control (ALC) circuit governs the signal strength going into the power amplifier in a ham radio transmitter.
