Pre-setting for Reception i

Use of RIT Switch

The RIT (Receiver incremental Tuning) switch is used to shift the receive frequency by about f 1.5 kHz without affecting the transmit frequency (the indication of digital display remains unchanged).

When the receive frequency is offset, turn on the RIT switch (the RIT indicator will light) and turn the RIT control so that the transceiver is tuned in the frequency.

Note that the receive frequency is offset from the

transmit frequency when the RIT switch is turned on, so the switch must be set to OFF after QSO.

Use of RF GAIN Control

This is used to adjust the receiver RF Stage gain. Normal- ly, leave it fully clockwise. for a very strong incoming Signal, turn it counterclockwise. If there is a strong Signal in the vicinity of your operating frequency, lower the RF gain to reduce intermodulation interference.
