Don't transmit using "compression" (also known as a speech processor). 5. Be sure your ALC is within its specified operating region. If in doubt, lower audio output seems to work better than a higher setting.
Remember, to receive SSB transmissions, you need to set the ARD9000MK2 to SSB mode, and in FM mode to receive FM transmissions. The operation modes can be selected with the MODE SWITCH, and described in the chapter, “Controls and Functions”.
