FCC WARNING BEFORE STARTING Amateur radio regulations vary from country to country. Confirm your local amateur radio regulations and requirements before operating the transceiver. Depending on the size and type of vehicle, the maximum transmission output power for the mobile operation will vary. The maximum transmission output power is usually specified by the car manufacturer to avoid interference with other electric devices used in the vehicle. [. . . ] G-TOR (Golay-coded Teleprinting Over Radio) is a relatively new Amateur Radio digital mode currently in use. G-TOR was developed specifically to handle the adverse conditions of communicating across the solar system with spacecraft during their missions. PSK31 was developed by an RTTY enthusiast, G3PLX, in the United Kingdom. The operating technique is very similar to the conventional BaudotRTTY, although more sensitive fine-tuning is required, as a PSK31 signal requires a tuning accuracy of a few Hertz. A special feature of PSK31 is that it allows the entire ASCII character set, including the back space character. For available modes on your MCP, consult the instruction manual for the MCP. For the cable connections, refer to "MCP AND TNC" {page 78}. On most HF bands, audio frequency shift keying (AFSK) is used for the above modes. This method of modulation uses audio tones, therefore either LSB or USB mode should be selected. Traditionally, LSB is used, similar to RTTY, with the exception of AMTOR which is normally operated in USB. These are also good starting places when searching for PacTOR, CLOVER, G-TOR, or PSK31 stations. The TS-480 transceiver has special DSP filters for these digital modes. Refer to page 48 for details. Note: When using SSB mode for digital operation, use a fast AGC setting and switch your Speech Processor OFF. PACKET RADIO Packet is a unit of data transmitted as a whole from one computer to another, on a network. Packets can be transmitted on radio waves as well as on communications lines. Besides a transceiver and a computer, all you need is a terminal node controller (TNC) or Multimode Communications Processor (MCP). One of the tasks of TNCs and MCPs is to convert data packets to audio tones, and vice versa. Connecting a TNC to this transceiver allows you to use many packet applications. A variety of packet applications developed by hams include packet bulletin board systems (PBBSs). PBBSs are created and maintained by volunteers called System Operators (SysOp). You may access one of your local PBBSs to send e-mail, download files, or obtain various useful information. Thousands of PBBSs, which have formed a worldwide network, relay e-mail to their intended destinations around the world. PBBS When you access a local PBBS for the first time, you often need to register as a new user. After you are successfully registered, it will then be available as your home PBBS. [. . . ] In this case, relocate the TX/ RX unit so that air can easily flow through the TX/ RX unit to keep the unit cooled. INTERNAL BEATS On some spots of the receiver frequencies, the S-meter moves or you cannot receive any signals. 15. 600. 00 MHz, 31. 200. 00 MHz, 46. 800. 00 MHz AGC When you turn the AGC function OFF {page 35}, the receiving audio signals can be distorted. In this case, decrease the RF gain, turn the pre-amplifier OFF, or turn the attenuator ON. In general, the RF gain must be greatly reduced when the AGC is turned OFF. 60 m BAND OPERATION (K-TYPE/ U.
