11 SPECIALIZED COMMUNICATIONS PREPARATION 1 Connect the transceiver to your personal computer (via an external TNC or MCP if desired). • See "COMPUTER" {page 93} and "MCP AND TNC" {page 95}. 2 Install an appropriate terminal program onto the personal computer. • A variety of freeware and shareware programs can be obtained in various ways. Consult your reference material or other "packeteers". 3 Initiate the terminal program and set the following parameters on the personal computer: • Transfer rate (TNC/MCP Computer): 9600 bps (default setting) • Data length: 8 bit • Stop bit: 1 bit • Parity: Non-parity • Flow control: Hardware 4 Press [A/B] to select VFO A or VFO B. 5 Access Menu No. 46 and select the main band or the sub-band (default) as the data band. • "TNC" appears on the data band. • If you are using an external TNC or MCP, access Menu No. 50E to make this selection. The default is main band. 6 Access Menu No. 47 and select 1200 bps (default) or 9600 bps as the transfer rate between TNCs. • You must select the same transfer rate as the target station. • If you are using an external TNC or MCP, access Menu No. 50F to make this selection. The default is 1200 bps. 7 Select an operating frequency. 8 Press [LSB/ USB/ AUTO] or [FM/ AM/ NAR] to select LSB, USB, or FM mode. 9 Access Menu No. 50A and select ON to activate the DSP packet filter for the main transceiver. 10 Turn the HI/ SHIFT control to select the center frequency of the packet mode. You can further select either "NAR" (narrow) or "WID" (wide) for the receiver filter width by turning the LO/ WIDTH control. Center Frequency 1000 Hz 1700 Hz 2210 Hz PSK Operating Mode PSK31 Packet (AFSK 1200 bps) Packet (AFSK 300 bps) PSK Note: ◆ The packet (9600 bps) operation is not affected by the DSP packet filter settings. ◆ The DSP packet filter works only on the main transceiver. If you are using an external TNC or MCP, proceed with the subsequent steps. 11 Following the instructions provided with your TNC or MCP, enter the calibration mode so that you can generate a mark condition. • The MAIN band LED changes from green (RX) to red (TX). 12 Access Menu No. 50B to select the appropriate AF input level. • Select a proper input level, so that the ALC meter reflects within the ALC zone. 13 Exit the calibration mode. • The MAIN band LED changes from red (TX) to green (RX). 14 Access Menu No. 50C to select the appropriate AF output level. • You cannot use the AF control to make this adjustment. • If you have selected sub-band in step 5, access Menu No. 50D instead. The frequencies (measured in kHz) commonly used for Packet are listed below: U.S.A./ Canada IARU Region 1 (Europe/ Africa) 1800 ~ 1830 - 3620 ~ 3635 3590 ~ 3600 7080 ~ 7100 - 10140 ~ 10150 - 14095 ~ 14099.5 14089 ~ 14099, 14101 ~ 14112 18105 ~ 18110 - 21090 ~ 21100 21100 ~ 21120 28120 ~ 28189 28120 ~ 28150, 29200 ~ 29300 50600 ~ 50780 - 144910 ~ 145090 - 440975 ~ 441075 430050 ~ 431025 DCD SENSE You can also select the method for inhibiting the builtin TNC from transmitting. Access Menu No. 48 and select one of the two methods. The default is "TNC BAND". TNC BAND: The TNC does not transmit when signals are present on the TNC (data) band. MAIN&SUB: The TNC does not transmit when signals are present on the main transceiver or sub-receiver. 50

You can also select the method for inhibiting the built-
in TNC from transmitting.
Access Menu No. 48 and
select one of the two methods.
The default is “TNC
BAND”.
TNC BAND:
The TNC does not transmit when signals are present
on the TNC (data) band.
MAIN&SUB:
The TNC does not transmit when signals are present
on the main transceiver or sub-receiver.
