4 Press [-] (F4) or [+] (F5) to select "On" or "Off". The default is "Off" (transmitting at the mark frequency by shorting pin 2 to GND). Selecting "On" allows the transceiver to transmit the space signal shifted for the mark frequency. 5 Press [ ] (F1). 6 Press [MENU] to exit. USING AN EXTERNAL DEVICE FOR RTTY MODE OPERATION You can use an external device and operate the transceiver in RTTY (FSK) mode without using the built-in demodulator, encoder or decoder built in the transceiver. Connect to the transceiver a TNC suitable for RTTY communication or a PC that allows the use of applications for RTTY communication so that you can operate the transceiver in RTTY (FSK) mode. Refer to the following page for operation examples. • Connection to a PC {page 1-5} • Connection to other transceiver with TNC terminal {page 1-8} Note: ◆◆If the shift width for RTTY mode exceeds 170 Hz, the audio peak filter for the selected band cannot be enabled ASSISTING YOUR SMOOTH QSO 5 AUDIO PEAK FILTER For operation in RTTY mode with an external device connected to the transceiver, this filter will improve the readability of the RTTY message. 1 Press [FSK/ PSK/ REV] to enter RTTY (FSK) mode. 2 Press [APF] to enable the Audio Peak Filter. The "APF" LED lights. Note: ◆◆You cannot enable the Audio Peak Filter until "170 [Hz]" is configured for Menu 2-06, "FSK Spacing". ◆◆Even if Audio Peak Filter becomes active, the Audio Peak Filter does not apply to the internal demodulator. PSK OPERATION The transceiver incorporates a demodulator, encoder and decoder for PSK31 or PSK63 operation. You can use a commercially available USB keyboard in combination with the transceiver for operation in PSK31 or PSK63 mode. You can also use a PC and software for operation with the transceiver. PRECAUTION ◆◆For transmission in PSK mode, adjust the drive until the ALC meter just begins to swing. If you use an external device, adjust the audio signal level of the external device so that the ALC meter just begins to swing. Contents Index 5-51
