Using The Transceiver For Packet Communication - Yaesu FT1DR Operating Manual

Using the transceiver for packet communication

You can perform packet communication with your transceiver by connecting TNC
(Terminal Node Controller) using an optional connection cable (CT-44).
After TNC is connected, set the level of output to TNC by adjusting the sound volume
level of your transceiver.
Also adjust the level of input to your transceiver using the output level adjustment
volume on the TNC (Input level cannot be adjusted on your transceiver)
Caution
z When sending a vast volume of data, the transmission takes a longer time and the transceiver may
be overheated.
If the transmission is continued for a long time, the overheat prevention circuit will operate and the
transmission power decreases. If the transmission is continued further, the transmission will be
automatically stopped to prevent the transceiver from overheating and consequently malfunctioning.
The transceiver will return to the receive mode.
When the transceiver returns to the receive mode after the overheat prevention circuit has operated,
turn the transceiver off, or keep it in the receive mode until the temperature cools.
Tips
• Set the Receive Battery Save function to OFF during packet communication by selecting
[8 CONFIG] [17 SAVE RX] in the Set mode.
• The reception can be interfered with a noise generated from PC.
If the transceiver can not receive normally, disconnect it from the PC and reconnect it to the PC
using a photocoupler or noise filter.
• To connect the TNC and PC, refer to the TNC instruction manual.
