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
![Page 9: WELCOME](https://reader033.vdocuments.us/reader033/viewer/2022051700/568161e5550346895dd2033d/html5/thumbnails/9.jpg)
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

• 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.
What is Outpost ?
![Page 24: WELCOME](https://reader033.vdocuments.us/reader033/viewer/2022051700/568161e5550346895dd2033d/html5/thumbnails/24.jpg)
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.

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

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

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
