Ham Radio Packet Overview
What is Ham Radio Packet?
•
Amateur packet radio is one of many digital modes that hams can use.
•
Packet Radio is used to transmit digital data by radio or other wireless
communications links.
•
Packet radio can send to or retrieve “mail” from a packet Bulletin Board
System (BBS).
Typical Packet System
Computer:
Runs the packet software that communicates with the BBS.
TNC:
Terminal Node Controller; the interface between your radio and
your computer (similar to a telephone modem).
Radio:
Set to the frequency of the BBS and other packet stations.
Antenna:
Connected to the Radio.
Power Supply: Powers the Radio and TNC; could also be a battery.
Why use Packet Radio?
1. BBSs allow messages to be stored, retrieved, or forwarded throughout the
connected BBS network.
2. The recipient does not need to be on line to get the message, meaning that
messages can be retrieved at the recipient's convenience.
3. Packet is ideal for passing lists of material, addresses, instructions, or
complex words (e.g. pharmaceuticals or chemicals)
4. We would use packet radio for the same reasons we would use internet
email: message accuracy, delivery, and the ability to handle message
complexity.
5. The Santa Clara County Emergency Management Association (EMA) knows
that our local communications infrastructure
WILL FAIL
during an
earthquake and
expects
Ham Radio to enable the response and speed the
recovery. Packet Radio is part of the response.
