PACKET OPERATION
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.
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.
