2.4 Practical Techniques for SSB Operation
Introduction
In SSB operation, you may encounter various problems such as poor propagations and
interferences. This section explains how to use the special functions to overcome these problems.
Eliminating Interference (QRM)
1: Activating the IF SHIFT function
This function eliminates interference by shifting the fi lter pass band without changing the
receive frequency.
Turn the 'IF knob clockwise or counterclockwise to lessen interference.
2: Using the fi lter
Press the [FUNC] key, then press the [RF] key. “Nar” appears on the display indicating
that the narrow fi lter is selected.
3: Activating the RF attenuator
When the received signal is noisy, it is possible that you are picking up another strong
signal from nearby.
Press the [RF] key to activate the attenuator to a desired level.
