For a detailed explanation on transmitting, refer to sections in “BASIC COMMUNICATING” beginning on page 20.

Note: When CW, FSK, or AM is selected, the transmit carrier level is automatically adjusted according to the selected mode.

MICROPHONE GAIN

The microphone gain is finely adjustable in the SSB or AM mode. A different level can be selected between when the Speech Processor {page 32} is ON and when the Speech Processor is OFF.

SELECTING TRANSMIT POWER

It’s wise, and required by law, to select the lowest transmit power that allows reliable communication. Reducing power lowers the risk of interfering with others on the band. On this transceiver, it is possible to change output power while transmitting.

1Press [PWR].

• The current transmit power appears.

QUICK MEMO

•SSB/CW/FSK/FM: Transmit power can be changed from 5 W to 100 W in steps of 5 W.

•AM: Transmit power can be changed from 5 W to 25 W in steps of 5 W.

2Press [SEND] or press and hold Mic [PTT].

• “TX” appears.

3SSB: While speaking into the microphone, adjust the MULTI/CH control so that the ALC meter reflects according to your voice level.

AM: While speaking into the microphone, adjust the MULTI/CH control so that the calibrated power meter slightly reflects according to your voice level.

4Press [SEND] again or release Mic [PTT].

• “TX” disappears.

5Press [MIC] again.

For the FM mode, set the microphone gain by accessing Menu No. 17 {page 17} and selecting either “L” (low) or “H” (high).

Note:

◆When using the optional MC-90 microphone in FM mode, select high microphone gain. The microphone sensitivity is low in FM mode and this may cause insufficient modulation.

◆When using a microphone that has an amplifier, be careful that the output of the amplifier is not too large.
