I'd like to set up a TNC with a Bit-Regenerator. Someone suggested that
I look at using a TAPR DCD board and connect up the TX<->DX lines. Anyone
know if that will work. Is there a standard circuit someplace? I'll
probably start with a TNC-2 clone at 1200b. We still don't have any
> 1200b activity in the area yet. If we do use G3RUH modems in a TNC-2,
how do you set that up as a bit regenerator?
Last question... what about the Firmware in the TNC? What are my
options. The setup will be running Full-Duplex. Any chance we can use
a TheNet X1G EPROM? I'd like to be able to have a PC connected to the
TNC, but not be involved in the Bit-Regeneration process. But I'd
like to be able to have the PC use the TNC. That might be stretching it
a bit. Any info or ideas would be appreciated.

CAPRA - the Chicago Area Packet Radio Association has arranged to
obtain a supply of Ian Wade, G3NRW's new TCP/IP primer -
"NOSintro." Reviews of this book have been quite good.
This 356 page book is a hands-on tutorial with documentation
regarding TCP/IP and NOS software version of this international
standard as implemented for use with amateur packet radio
operations.
An earlier posting listed all of the 35 chapters of the book
which outline the basics and more advanced topics of TCP/IP;
there are 6 Appendices with additional reference materials and
information. The book has over 80 detailed diagrams with
"countless examples of commands and screen displays".
The books will be shipped via U.S. Postal Service's 2nd Day
Priority Mail service upon receipt here in suburban Chicago.
Ian Wade, the author, has given us a discount for our quantity
purchase. The cost to you will be slightly under the total cost which
you would have were ordering directly from the publisher in the U.K.
This is NOT a money making undertaking on the part of our group.
Many of us are active on TCP/IP and feel that this is a way to
increase the awareness of and technical expertise of others who
may be interested in or who are currently using the protocol in
amateur radio circles.
Send your complete mailing address, a telephone number at which
you can be reached should there be a problem, and a check/money
order made out to CAPRA in the amount of $22.50. Canadian hams should
send $24.00 in the form of a Canada POST International Money Order
payable in U.S. dollars.

CAPRA - (Chicago Area Packet Radio Association)
Presents: TCP/IP - Seminar/Workshop
The interest in TCP/IP (Transmission Control Protocol/Internet
Protocol) in the radio amateur community has been increasing rapidly
in the past year or two. Unlike regular AX.25 packet, TCP/IP is
somewhat complex to set up and operate. More than with any new mode,
there seem to be many people frustrated in their attempts to get
started. As an aid to those interested in TCP/IP, CAPRA will conduct
a hands-on, seminar and workshop.
TCP/IP is used extensively in telecommunications networking in
government, educational, and corporate organizations. It includes
several capabilities including unattended electronic mail exchange,
retrieval/forwarding of files of information, software, and other
materials to/from several hundred thousand computer systems throughout
the world, incorporating hundreds of gigabytes (billions!) - pieces of
information of all kinds, and, connectivity which allows authorized
users to "operate" computer systems at distant points.
As implemented in the amateur community today, there are gateways
to/from the amateur packet networks to the Internet (world-wide
computer system networks), as well as to far distant amateur packet
radio networks throughout North America, Europe, Australia and other
points. Some, but not all of the capabilities of the amateur networks
can be used with the AX.25 protocol; however, TCP/IP is "richer" and
has greater capabilities to allow one to "reach out" to other amateurs
and varied resources through the world as indicated above.
The seminar/workshop will:
- introduce you to the "basics" of TCP/IP
- introduce the amateur radio packet software package -- NOS
- explain the hardware requirements for using TCP/IP
- provide demonstrations via "hands-on" stations for your use at the
workshop
- allow you to "prepare" a personalized copy of NOS for installation
at your own station QTH
- discuss the backbone network in Metropolitan Chicago including links
into the Internet
- answer questions, questions, questions...
When: Saturday, May 15, 1993
8:00 AM - Doors Open
8:30 AM - First Session
12 Noon - Presentation Conclusion
12 Noon - 1:00 PM - Lunch
1:00 PM until ??? - Discussion, Hands On, Prepare NOS Disks, Questions

Other:
- A brief written tutorial on TCP/IP is being prepared; if you are not
familiar with the topic, you are urged to obtain a copy for review
prior to the seminar/workshop. Please send $2.00 to the CAPRA Post
Office Box prior to May 1, 1993.
- If you plan on preparing a personalize copy of NOS for your station,
bring the appropriate MS-DOS or MAC diskettes (minimum 3, just in
case)
