Previous view 3 BASIC OPERATION Basic transmit operation Before transmitting, monitor the operating frequency to make sure transmitting won't cause interference to other stations on the same frequency. It's good amateur practice to listen first, and then, even if nothing is heard, ask "Is the frequency in use?" once or twice, before you begin operating on that frequency. DDTransmitting CAUTION: Transmitting without an antenna may damage the transceiver. In the AM mode, you can transmit on only the HF, 50/70* MHz frequency bands. * 70 MHz band transmission is available, depending on the transceiver version. qqPush [PTT] on the microphone to transmit (or external transmit switch). • The TX/RX LED lights red. w R elease [PTT] again to receive (or external transmit switch). ✔ Adjusting the transmit output power qqPush MIC/RF PWR (C) to open the MIC gain/RF power adjustment display. wwRotate [BANK] (L) to adjust the RF power. eePush MENU (C) to close the display. Frequency band RF output power range HF/50 MHz 2 to 100 W (AM: 1 to 30 W) 70 MHz* 2 to 50 W (AM: 1 to 15 W) 144 MHz 2 to 50 W 430 MHz 2 to 35 W * 70 MHz band transmission is available, depending on the transceiver version. NOTE: The RF output power settings are independently memorized in the HF, 50, 70, 144 and 430 MHz bands.
