Why are we here ?

… and, why are we talking about packet ?

 Emergency Management, Police, Fire, EMS  Hospitals, Nursing Homes, Schools  Red Cross, Salvation Army INFORMATION -- DATA  Amateur Radio  Volunteerism! - a desire to help  Communications  Structure

Why are we here ?

… and, why are we talking about packet ?

What is Packet Radio ?

… in a nutshell

 One of many digital modes that hams can use to build wireless computer networks  Built on the AX.25 protocol, a mature extension of the industry standard X.25

 Transparency  Error correction  Automatic control  Data transfer speeds from 300 baud up to 19.2 kb  frequency dependent; higher speeds = wider bandwidth

What is Packet Radio ?

… the advantages

 Error free  Date/time stamp messages  Can provide a message hard copy  Single frequency - “store & forward”  Relatively low cost  Reliable  Scalable  Self-building infrastructure

What is Packet Radio ?

… the advantages

 Long Messages  We know to keep it under 25 words; served agencies often don’t/won’t  Complex Messages  “Need to swap 22 20-gallon drums of acetalethelhexabadstuff for 4 4-gallon drums of phenylbromotetragoodstuff”  Lists of names, addresses, phone numbers, call signs, etc.

 High Volume Messages  Transmit, log, and print much faster than by voice

What is Packet Radio ?

… the disadvantages

 Requires operator training  Specialized hardware needed  Minimum number of stations required for an effective network  Duplication of radio equipment required to maintain 2M voice operations for nets  May interfere with co-located 2M voice operation  Single frequency reduced throughput  Slow speeds compared to Internet

What is Outpost ?

• A Windows-based packet messaging client • Supports ARES, RACES, and other emergency response teams and their need to pass digital traffic • Helps automate the packet message handling environment • Manages all message-handling between you and your BBS • Lets you read, delete, create, reply to, or forward messages back to the BBS • Outpost is a software layer that provides a nice user interface to the complex world of packet operations, TNC usage, and BBS commands.

Why use Outpost ?

• Leverages the existing packet hardware, network, and BBS infrastructure • Compatible with many existing BBSs and TNC PBBSs • Uses your existing TNC and packet radio equipment • Hides the complexity of the packet operating environment • Similar look and feel to contemporary email programs • Shorter learning curve for packet operations • Allows users to… “

focus on the message, not the medium

” • Implements most local emergency management policies for digital communications • Still under active development based on user requests and on going alignment with the Outpost mission.

Installing Outpost

… to communicate with your TNC

Desktop Icons  Ipserial  Outpost PMM

Installing Outpost

… to communicate with your TNC

USB-to-Serial Port Converter

… to communicate with your TNC

No serial port on your computer?

 Converters with FTDI chipsets work best  Get latest drivers for your OS

USB-to-Serial Port Converter

… to communicate with your TNC

USB-to-serial port converter installed – now what?

 Determine what COM port Windows assigned to it

Connecting TNC to Radio

… difficult part #2

 4 connections between radio and TNC

Connecting TNC to Radio

… difficult part #2

 6-pin mini-DIN “data” or “packet” connector  Industry standard adopted by all Japanese manufacturers  Less expensive radios do not have it

Connecting TNC to Radio

… difficult part #2

 “Roll your own” or buy pre-made  Must be built for your specific radio and specific TNC

Connecting TNC to Radio

… difficult part #2

 Audio levels are critical for proper operation  Radios with mini-DIN connectors make it easy  Using speaker jack requires careful volume adjustment (usually about 1/3 up)  Unsquelch radio when using KPC-3 with “CD software”  Set squelch just above threshold when using other TNC

The Packet Station

… ready for action

 Relax  Believe it or not, the hard part is over.

 Have fun while you learn  “Playing” on packet actually develops your skills

The Packet Network

… what is it exactly?

 Digipeater  Node (TCARES, CYCLON, INHOWA, NOIRAM)  PBBS (W9TCA-1, AB9LE-1, WR9A-1, etc.)  “Full service” BBS (aka: cluster)  BBS  Conference room  Multiple ports  Backbone access / Internet access  Backbone

What is Packet Radio

… what can we connect to ?

Why use Packet Radio ?

… the case for packet

 BBS Message “Store and Forward”  Message storage, retrieval, and forwarding  Messages stored for retrieval at any time

Why use Packet Radio ?

… the case for packet

 Home stations with Internet access can greatly enhance the local packet network’s capabilities

Why use Packet Radio ?

… the case for packet

 Full-service BBSs and nodes often use another frequency to exchange large amounts of data  This is known as the “backbone”  Internet can also be used to link BBSs & nodes

Why use Packet Radio ?

… interoperability

What if I …

… can’t access the local BBS directly ?
