2.10 Practical Techniques for CW Operation
Introduction
In CW operation, you will encounter various problems such as poor propagations and
interferences. This section explains how to use the special functions to overcome these problems.
Reducing Interference
1: Activating IF SHIFT function
This function eliminates interference by shifting the fi lter pass band without changing the
receive frequency.
Turn the 'IF control knob clockwise or counterclockwise to reduce interference.
2: Using the fi lter
Using the narrow fi lter in conjunction with the IF SHIFT function will more effectively
eliminate interference.
To use the CW fi lter, press the [FUNC] key then press [RF] key. Repeat to disengage.
3: Activating BFO REVERSE function
Select the CWU or CWL mode.
If your station and the other station are zeroed-in, this function will not change the •
receive tone and transmit frequency. See page 64 for more details.
4: Activating the RF attenuator
The attenuator can protect the received signal from suppression and cross-modulation
caused by neighboring signals.
Communicating in Bad Conditions
Activating the RF preamplifi er
Press the [RF] key repeatedly until [+10] appears.
The preamplifi er will come on.
Activating the RIT function
Press the [RIT] key and rotate the RIT control knob to clarity the signal.
Communicating in Pile-ups
Selecting the FULL BREAK-IN mode
In this mode, keying will transmit and un-keying will receive automatically. This allows
you to call with perfect timing.
Select the FULL break-in mode in the Set mode (see page 79).
