Chapter 2 Communications
Communicating in Bad Conditions
In HF band, propagations depend on time, season, and propagation paths. For example, signals
from the other station may fade or alternate between strong and weak. In this case, perform the
following.
1: Using the RF preamplifi er
Press the [RF] key repeatedly until [+10] appears.
2: Selecting the AGC-F mode
In the SSB mode, the AGC-S mode is usually selected. However, if there are strong
signals or noise near a weak signal, the signal is suppressed by the strong signals or noise.
In this case, select the AGC-F mode to improve recieving conditions.
Press the [FUNC] key, then press the [MHz] key the "AGC-F" appears on the display.
Communicating with Off-frequency Stations
When communicating with a station that drifts his transmitting signal (QRH), use RIT so that
you can fi ne-tune to his transmitting frequency without shifting your transmission signal.
Activating the RIT function
Press the [RIT] key and rotate the RIT control knob to fi ne-tune to the receiving
frequency.
The RIT operation does not change your transmit frequency so that the other station •
does not need to shift the receive/transmit frequency.
Communicating in Pile-ups
Speech compressor increases the average power of the transmitted signal by amplifying the weak
part of your speech. It helps communicating in poorer propagation conditions or in pile-ups.
NOTE: Pile-up - the condition where many stations call one station at the same time.
Using the speech compressor
Set the speech compressor to "ON" in the Set mode (see page 81).
NOTE: Speech-compressed signal may sounds distorted or unnatural in better communication
conditions.
