2. SSB RADIOTELEPHONE

Checking the transmitting power

During transmission, the IA bar deflects according to the current being fed to the antenna feeder from the antenna coupler. The unit of readout is amperes. The antenna current varies with the effective antenna impedance. The reading differs by the frequency and antenna length. The output power is proportional to the square of an antenna current.

2.4Receiving

Check if the emission mode and receiving frequency are set properly. If necessary, set them again referring to section 2.1 and 2.2.

2.4.1RF gain (sensitivity) adjustment

In normal use the sensitivity should be set for maximum. If the audio on the received channel is unclear or interfered with other signals, adjust (usually reduce) sensitivity to improve clarity.

1.Rotate the ENTER knob to choose SEN in the equipment states area and then push the ENTER knob.
