PACKET OPERATION

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). A TNC converts packets to audio tones and vice versa as one of its tasks. This transceiver has a built-in TNC.

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 a file, or obtain various useful information. Thousands of PBBSs, which have formed a worldwide network, relay e-mail to its intended destination 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. E-mail addressed to you will be hold under a directory, called a mailbox, on your home PBBS.

To send e-mail, you must designate the address of a recipient, using his (or her) call sign and the call sign of his (or her) home PBBS; ex. KD6NUH@KJ6HC. In this example, e-mail is addressed to KD6NUH whose home PBBS is KJ6HC. If your home PBBS cannot find KJ6HC in its address file to forward your mail, you must designate the address in more detail. You may enter “KD6NUH@KJ6HC.#ABC.CA”, or “KD6NUH@KJ6HC.#ABC.CA.USA”, or up to “KD6NUH@KJ6HC.#ABC.CA.USA.NA”, as necessary. The complete address of a recipient living in the U.S., for example, should include an appropriate region code (preceded by a #), state, country, and continent abbreviations as above.

For further information, consult reference books which should be available at any store that handles Amateur Radio equipment. If you are living in the U.S., refer to the ARRL Repeater Directory for packet frequencies. Web pages relating to Packet will also be helpful. On one of the Internet search engines, you may use “Packet Radio" as a key word to find those Web pages.

Note: If there is an amateur radio club in your area, consider becoming a member. You can learn more in an hour from experienced hobbyists, than in a month of independent research. Ask on the local repeaters, or contact your national amateur radio organization (in the U.S., the ARRL) for information on local amateur radio clubs. You'll be glad you did.

This transceiver has a built-in TNC which conforms to the AX.25 protocol. This protocol is used for communications between TNCs. The TNC accepts data from your personal computer and assembles it into packets. It then converts packets to audio tones which the transceiver can transmit. The TNC also takes audio tones from the transceiver, converts them to data for the computer, and checks for errors in the data.

The TNC mainly functions in Command or Converse mode. First learn the difference between these two modes.

• Command mode When you select Packet mode, the TNC enters this

mode. A “cmd:” prompt appears on the computer screen. You can type commands from the computer keyboard to change the settings on the TNC. When in Converse mode, press [Ctrl]+[C] on the keyboard to restore the Command mode.

• Converse mode The TNC enters this mode when a linkage with the

target station is established. On the computer keyboard, type an appropriate command and if necessary a message, then press [Enter] or [Return]. What you type is converted into packets and transmitted over the air. When in Command mode, type CONVERSE to restore the Converse mode; you can also type CONV or K instead.

For the commands supported by the built-in TNC, see “TNC COMMANDS LIST” on page 41.

The following indicators appear on the transceiver display to show the current TNC status:

The built-in TNC includes a simple mailbox to directly receive mail from other stations; the mailbox holds up to approximately 110 kilobytes (KB) of information. You can read mail from the mailbox by sending a command from your personal computer {page 47}.

Note:

◆

Not all functions available via conventional TNCs are supported by the TNC built in this transceiver.

◆

The built-in TNC could be automatically reinitiated when its malfunction is detected; this does not designate that the transceiver is defective.

◆

To distinguish your various stations or nodes, you can have up to 15 Secondary Station IDentifiers (SSIDs); ex. WD6BQD-1 to WD6BQD-

15. You always have to put a dash between your call sign and SSID number.

◆

Packet operation, easily affected by transmit and receive conditions, requires a full-scale S-meter reading for reliable communication. When the S-meter reads less than maximum during 9600 bps operation, communication errors are frequent.

PREPARATION FLOW

The following steps should guide you to a good start of packet operation. The shaded steps indicate operations

on your personal computer. First connect the transceiver to the personal computer {page 2}.

Note: You must not change the default (9600 bps) in Menu 1–9–5 (COM PORT).

q Install an appropriate terminal program on the

personal computer.

• A variety of freeware or shareware programs can be obtained in various ways. Consult your reference material or other “packeteers”.

w Initiate the terminal program and set the following

parameters on the personal computer:

• Transfer rate (TNC <–> Computer): 9600 bps

• Data length: 8 bit

• Stop bit: 1 bit

e Access Menu 1–6–1 to select band A or B as the

data band {page 5}.

r Press [F] (1 s), [TNC], then [F] (1 s), [TNC] again

to enter Packet mode.

•“TNC PKT” should appear.

t To select 9600 bps as the transfer rate from/to the

target station, type HBAUD (or HB) 9600 and press [Enter] or [Return]. The default is 1200 bps.

• You must select the same transfer rate as the target station.

y Type MYCALL (or MY) then your call sign (9 digits

max.) and press [Enter] or [Return] to set your call sign on the TNC.

• You cannot use the default setting (NOCALL).

u Tune to an appropriate frequency.

• First you may want to monitor packets which are transmitted among other stations. When packets are received, text appears and the computer screen scrolls.

i To connect with the target station, type

CONNECT (or C) then its call sign and press [Enter] or [Return].

• When a linkage is established, a message informing you of this appears on the computer screen; on the transceiver display, “CON” appears.

• If packets from other stations keep your squelch open, adjust the squelch level in advance. The TNC cannot transmit while the squelch is opened.

o Send appropriate commands and, if necessary,

messages to the target station via the TNC.

SELECTING DATA BAND

DCD SENSE

This transceiver is capable of receiving packet data on one band (data band) while receiving audio on the other band. In order to use the built-in TNC, access Menu 1–6–1 (DATA BAND) and select band A or B as the data band for receiving or transmitting packets. “ ” indicates the current data band; the default is band A.

Note:

◆

PACSATs refer to satellites designed and launched for digital communications using the AX.25 protocol. Several PACSATs are currently in orbit serving thousands of hams throughout the world. The PACSATs receive (uplink) on VHF and transmit (downlink) on UHF. Some of them use FM to receive and SSB to transmit, and operate at 1200 bps. The others use FM to both receive and transmit, and operate at 9600 bps. This transceiver allows communications with the 9600 bps satellites. The PACSATs provide functions similar to terrestrial PBBSs. You can use the satellites to send email, download a file, or enjoy other fascinating activities. From the satellites equipped with high resolution cameras, you may download still pictures taken in space.

In order to work the PACSATs, you need rotators that allow azimuth and elevation control, plus high-gain directional antennas. Your antenna has to track satellites which travel from horizon to horizon. However, many hams have been successfully using fixed omnidirectional antennas. As for software, you need dedicated programs capable of working the “broadcast” protocols. Besides the “broadcast” programs, various utilities which will ease your operations are available via the Web pages of the Radio Amateur Satellite Corporation (AMSAT); the world wide organization of Amateur Satellite operators and supporters.

For further information, consult Internet Web pages relating to the PACSATs. On one of the Internet search engines, you may use “PACSAT” or “AMSAT” as a key word to find those Web pages. It will also be wise to ask help to one of your local satellite packeteers.

The Automatic Packet/ Position Reporting System (APRS) is a software program and registered trademark of Bob Bruninga, WB4APR. He has made packet communications much more exciting than before. This program allows you to track mobile stations on a map which you recall on a computer screen. Imagine seeing one mobile station moving on the map which can be scaled from .5 to 2000 miles. You also may be tracked on the computer screen of another station.

Stations to be tracked must transmit beacons at certain intervals. To track other stations, you usually need a computer running the APRS, a transceiver, and a TNC. To have them track you, you also need a GPS receiver. It receives signals from the satellites to inform you of your current geographical position. GPS stands for Global Positioning System. The APRS interprets the National Marine Electronics Association (NMEA) data strings coming from the GPS receiver. For further information, consult Internet Web pages relating to the APRS. On one of the Internet search engines, you may use “APRS” or “Packet Radio” as a key word to find those Web pages.

This transceiver includes a TNC and a program for dealing with data formats supported by the APRS. That is, you need no other equipment to transmit, receive, or display APRS packets. You do not need even a GPS receiver if you enter position data manually to transmit. For hams who want to fully enjoy APRS operations, this transceiver has connection ports with a personal computer and a GPS receiver. This manual, however, does not describe APRS operations which require a personal computer.

Using this transceiver, you can transmit a station icon, position data, position comment, and status text. With a GPS receiver, you can also transmit moving speed, moving direction, and altitude data. From any type of station you will receive information listed below:

Depending on the types of stations, you will also receive the following information:

PACKET PATH AND DIGIPEATER

WIDE-type RELAY-type

A packet path specifies how APRS packets should be transferred via one or more repeaters. A repeater, which is used for packet transfer, is commonly called a digipeater. This came from a “digital repeater”. A digipeater is usually located on a mountain top or high building. Unlike a voice repeater, it operates on a simplex frequency. Each volunteer who installs a digipeater programs it either as a WIDE or RELAY type. Generally a WIDE transmits packets over much greater distances than a RELAY.

In any given area, there should be only one WIDE not to cause extra traffic or collisions on frequencies. A WIDE is capable of transferring packets from and to adjacent WIDEs. Like a WIDE, there should be only one RELAY in a given area; that area is usually much smaller than a WIDE. So, transmit packets to a RELAY when you cannot directly reach any WIDE. The RELAY then will transfer the packets to any accessible WIDE.

On this transceiver, you can edit a packet path using a maximum of 79 alphanumeric characters. The default is “RELAY,WIDE” that is one of the common settings. With this setting, packets will be transferred to a RELAY first, then to a WIDE.

The APRS supports various methods for specifying a packet path. Some of those methods are described on page 24.

This transceiver with a built-in TNC may be used as a digipeater. See page 27.

Note: To serve for mobile stations who always use the RELAY ,WIDE path, most WIDEs also respond to packets addressed to a RELAY.

CONNECTING WITH A GPS RECEIVER

The GPS jack on this transceiver accepts a 2.5 mm (1/10") 3-conductor plug. If necessary, use the supplied cable to modify the cable end of your GPS receiver .

The default APRS packet transfer rate set on the built-in TNC is 1200 bps which is the standard among the current APRS networks. If APRS networks which use 9600 bps transfer rate become available in the future, access Menu 3–J (PACKET SPEED) and select “9600 bps”.

Each time a new APRS packet is received, the frequency display is interrupted to show information as below:

Position comment (or status text)

• The received APRS packet may include information on an object such as a hurricane or tornado. In this case, the

name of the object appears instead of a call sign.

• Press [DETAIL] to access further information {page 15}.

• To restore the frequency display, press [ESC] or just wait for approximately 10 seconds.

Note:

◆

When you receive an APRS packet including an “Emergency” comment, a different format of display from the above will appear and a different beep will sound.

◆

When you receive an APRS position packet that you transmitted, the frequency display is not interrupted. “MY POS” will appear on the display. This could happen when one or more digipeaters {page 9} are used. If you receive a message {page 30} that you transmitted, “MY MESSAGE” will appear.

If a received packet does not include new (or proper) APRS data, the frequency display is not interrupted. An indicator such as “dP” appears depending on the types of data. See the table.

The transceiver automatically transmits the appropriate information in approximately 2 minutes after receiving a request.

Note: The APRS programs for PCs have entry fields for a position comment and status text. The data entered to these two fields are transmitted as separate packets. This transceiver, however, includes both of a position comment and status text in one packet to transmit.

This transceiver beeps each time it receives any type of APRS packet. You may access Menu 3–F (BEEP) to change this setting. The default is “ALL”. The selection in this menu is shared with APRS Message {page 29}.
