<title>Linux HAM-HOWTO, Amateur Radio.
<author>Terry Dawson, VK2KTJ, <tt>[e-mail]</tt>
<date>v2.0, 30 April 1996

<abstract>
It is hoped that this document will assist Amateur Radio operators in finding
and trying the various amateur radio software that has been written for or
ported to Linux. It is also hoped that as a consequence of this information
being available that more amateur radio operators will choose Linux as the
platform of choice for their experimentation, and that software developers
will choose Linux as the platform for their software development, further
expanding the role of operating systems like Linux in the Amateur Radio field.

<sect><heading>Introduction.
<p>
This list was prompted by comments that had been expressed in the various
Linux newsgroups about the number of amateur radio operators that were
involved with Linux. It is now clear that Linux is becoming a popular
platform for Amateur Radio development work.

This list was originally called the RADIOLINUX list, but has been moved into
the Linux Documentation Project HOWTO collection, so it has been renamed the
HAM-HOWTO. I make no apologies for the name.

<descrip>
<tag>Name
</tag>SatTrack
<tag>Author
</tag>Manfred Bester, DL5KR, [e-mail], [phone]
<tag>Description
</tag>Satellite realtime tracking and orbit prediction program with X11 color graphics.
<tag>Status
</tag>Version 3.1 has been released.
<tag>System requirements
</tag>A vt100 terminal and or X11 server. A Maths Coprocessor is useful, but not essential, for good performance.
<tag>Detail
</tag>SatTrack is a satellite tracking program that has been written in 'C' language on a UNIX workstation. It provides two different live displays, for single or multiple satellites, and two different orbit prediction facilities. Cursor controls used in both live displays are compatible with the VT100 standard, which allows the program to be run basically from any terminal. An optional X Window graphics display shows the typical world map tracking chart. The orbit prediction can be run either interactively or in a batch mode. In the latter case all necessary parameters are specified on the command line. The program uses the NORAD/NASA two-line Keplerian element (TLE) sets directly.
<p>
The current version of SatTrack can track a single satellite and/or display multiple satellites for a single ground station. It also can control suitable ground station hardware, like antennas and radio equipment, and has an autotrack mode in which it switches automatically between a number of specified satellites. For calibration purposes tracking of the Sun and the Moon are also provided. Future releases will provide more options. SatTrack requires about 5 MB of disk space in the full distribution with eight different world maps (2 styles, with 4 different sizes each, to fit everyone's screen and taste) and less than 1.5 MB of memory at run time. More information can be obtained from the <url url="http://www.primenet.com/~bester/sattrack.html" name="SatTrack WWW Home Page">
<p>
Compiling the software under Linux is quite straightforward. Manfred has designed the Makefile to compile the software directly under your home directory, this is easy to change.
<p>
The steps I took were:
<tscreen><verb>
# cd /usr/src
# export HOME=/usr/src
# gzip -dc sattrack-3.1.1.tar.gz | tar xvf -
# cd SatTrack/src
# vi Makefile
  {Comment SUN4 compile options}
  {Uncomment the linux options}
  {Select the options you want}
# make
</verb></tscreen>

<tag>Author
</tag>John A. Magliacane, KD2BD, <[e-mail]>
<tag>Description
</tag>A satellite orbital prediction program that also tracks the sun's
position to predict visible satellite passes.
<tag>Status
</tag>Complete and working.
<tag>System requirements
</tag>predict is a screen-oriented program that utilizes the ncurses-1.8.5
(or later) library.  A color terminal is a plus, but not a necessity.
<tag>Detail
</tag>Features of predict include azimuth and elevation headings of satellite
passes, orbital phase, sub-satellite point locations, slant ranges, orbit
numbers, and sunlight visibility as a function of date and time. The program
is simple, fast, and easy to use. Predict maintains an orbital database for
21 satellites that can be updated by the user through the keyboard or by using
files containing NASA 2-line orbital element data. Since this program operates
under a multiuser environment, each user on the system owns and maintains his
or her own unique orbital data base.
<p>
This program has been compiled using the highest level of compiler
optimization for high speed execution, and uses an a.out binary format for
greatest compatibility.
<p>

<p>
<descrip>
<tag>Author
</tag>Brandon Allbery, KF8NH, [e-mail]
<tag>Description
</tag>Brandon ported JNOS to Linux. His port is currently of the 1.09
(aka 1.08df) release of JNOS. Future versions will probably be based on Doug
Crompton's evolution of 1.08df. Brandon suggests that JNOS for Linux is
primarily of interest to people with existing DOS-based NOS configurations
(especially server/switch configurations) who wish to switch to Linux or to
escape the 640K barrier.
<tag>Status
</tag>Brandons code was rolled back into the main jnos distribution, so
development on the two runs in parallel.
<tag>System Requirements.
</tag>Any version of Linux along with <em>ncurses</em> 1.8.1 or 1.8.5
(the latter is preferred). Optionally you will require Linux networking
(at least loopback and slip).
<tag>Detail
</tag>
If you include the Linux networking code in addition to JNOS, you can link
the two by a slip link running over a pty, so that Linux can provide services
to your radio users. In this way you can easily add servers without having
to build them into JNOS itself.
<tag>Where and How to obtain it.
</tag>You can obtain JNOS for Linux ALPHA.4 at:
<url url="ftp://ftp.ucsd.edu/hamradio/packet/tcpip/jnos/jnos110i.zip"

</tag>Brandon's modifications to JNOS are public domain. Most of the
pre-existing NOS code is copyrighted and restricted to non-commercial
use by the various contributors from Phil Karn on.

<tag>Status
</tag>ALPHA. Bob is running version ARY-0.9 on both Linux and HP-UX. The next
version from N0ARY which is called 4.0 is in alpha test/development release.
Bob has not been able to bring this online yet and is still running 0.9+kf0uw
mods. Bob has about half it working with Alan Cox's AX.25 kernel which would
be the desirable combination.
<tag>System Requirements.
</tag>Linux installation, C Compiler, plus HAM radio TNC hardware.
<tag>Detail
</tag>This bbs has an excellent packet user interface.  It has a compatible
set of commands with the RLI bbs so users will be familiar with it immediately.
It then extends the command set to be a very nice natural language style
interface (e.g "list at allus about KPC-3"). Many csh style bang commands are
supported. Also included is a mail interface to provide a packet to internet
gateway.

Currently you need to customize the source code for your installation so you
need some C programming proficiency.

</tag>Kernel AX.25 support or the Wampes package. sendmail, CNEWS.
<tag>Detail
</tag>Daryl's aim was to build a platform on which amateurs could build a
Packet BBS to smtp gateway for Linux. I'm not sure what the current status
is as the last version I could find was dated 30 Jun 1995.
The latest binary version supports:
<itemize>
<item>MBL, FBB batching, FBB compressed, FBB type 1 compressed forwarding with
restart facility implemented, deferring, and rejection.
<item>various Linux transport mechanisms including TCP kernel, AX.25 kernel,
Wampes NetROM, AX25 or TCP.
<item>Simple dialer, to allow connections through AX.25 or NetROM nodes.
<item>White Pages
<item>Transient handling of type A (ACK messages).
<item>SMTP/NNTP<>BBS gatewaying implemented heavily to the extent that the
user front end will be accessing the NetNews spool to retrieve articles.
<item>Message filter mechanism
<item>Field swapping (like SWAPP.SYS in FBB).
<item>Multiuser/connect.
</itemize>
To install, I did the following:
<tscreen><verb>
# cd /usr/src
# mkdir LBBS
# tar xvfz LBBS-0.1.6A.tar.gz
# cd LBBS
# ./Install.sh

<tag>Author
</tag>Franta Bendl, DJ0ZY, and Bernhard ("Ben") Buettner, DL6RAI, [e-mail]
<tag>Description
</tag>A PacketCluster like system running on Linux.
<tag>Status
</tag>Released in October 1995.
<tag>System Requirements
</tag>Linux Kernel version 1.2.0 or greater with Alan Cox's AX.25 version 025
driver, TCP/IP networking, SysV IPC. Also needs Perl and KISS TNC hardware on
serial device.
<tag>Detail
</tag>PacketCluster nodes have been available for about six years. The original
software was written by Dick Newell, AK1A, and is running under DOS.
<em>clx</em> is a system which clones a PacketCluster node. To the outside
user commands and features are mostly identical, remote PacketCluster nodes,
which can be networked, don't see the difference between a generic
PacketCluster node and <em>clx</em>. So it fits well into an established
network of PacketCluster nodes.

<em>clx</em> is not a user application, it is network node software. As such it
is not of much use for the individual amateur. SysOPs of PacketCluster nodes
with some experience on both PacketCluster and Linux will find this
application interesting.

Here are some of the features of CLX:

<itemize>
<item>It is fully compatible with the internal PCxx protocol and from a users'
point of view. It allows multitasking and different priorities for different
things.
<item>The software detects looping DX spots without generating endless
messages. <em>clx</em> filters out such duplicate information. We have
implemented a concept which allows us to connect the network at multiple
points, which would formerly have been called a "Cluster Loop". <em>clx</em>
knows of so-called "active" and "passive" links. The outcome is that more DX
information is seen by clx.
<item>An interface to call your external programs (even dialog programs).
<item><em>clx</em> uses modern programming concepts like shared memory for
common data, lex & yacc to implement command language, shared libraries to
keep binaries small (this is still on our wish list), remote procedure calls
for inter process communication. It is strictly modularized with its own
dedicated process for every major task.
<item>Comprises the following modules:
<descrip>
<tag>con_ctl</tag>interfaces AX.25 kernel code and provides a socket for local users.
<tag>rcv_ctl</tag>manages receive spooling.
<tag>snd_ctl</tag>manages transmit spooling.
<tag>rm_disp</tag>receive message dispatcher, forwards messages to other processes.
<tag>usr_req</tag>user database requests, forks a process for every database task to make it run in the background. The background process later sends the results directly to send_ctl.
<tag>mb_ctl</tag>mailbox control. The mailbox keeps messages in a file system, header information is stored in the database.
<tag>usr_ctl</tag>user administration (logins, logouts, logbook).
<tag>usc_mng</tag>manages external user commands and command extensions.
<tag>iu_com</tag>inter user communication (talk, conference).
<tag>send_ctl</tag>transmit spooling, handling priorities.
<tag>icl_com</tag>inter node communication (processing and generating PCxx messages).
<tag>clx_ctl</tag>system administration, installing shared memory pages.
<tag>int_com</tag>manages internal program communications.

<tag>Author
</tag>Mark Wahl, DL4YBG, DL4YBG@DB0BLO.#.DEU.EU, [e-mail]
<tag>Description
</tag>A suite of programs that provide BBS and Terminal programs for Linux.
<tag>Status
</tag>Stable and working.
<tag>System requirements
</tag>TNC supporting WA8DED hostmode or KISS protocols.
<tag>Detail
</tag>TNT is a full featured hostmode terminal program. Compiling it on Linux
is as difficult as untarring the source and typing `make'. It provides both
a `dumb' terminal and X11 version. It comes with some comprehensive
documentation which describes its features in some detail. Its main features
are:
    <descrip>
    <tag>Multiple sessions:</tag>TNT supports multiple packet radio
    connections on virtual screens that you can switch between. Each session
    window provides split screen (seperate transmit and receive text)
    operation with a status line. Commands can be entered in either a command
    session, or in any terminal session using a command key. Each of the
    virtual screens can be larger than the physical screen and can be scrolled
    around.
    <tag>Data capture, file transfer and logging:</tag>A number of options are
    available for logging received text to files. You can log transmit, receive
    or both to a log file. You can overwrite or append received data to
    existing files. You can use the `autobin' protocol to transmit or receive
    binary files.
    <tag>Remote Shell operation:</tag>You can provide a shell to remote users
    so that they can access other programs on your computer. You can also run
    a program and direct its input/output to a channel so that users can use
    it.
    <tag>Redirection of devices to a channel:</tag>TNT allows you to redirect
    input/output from a channel to a device, a modem for example.
    <tag>Umlaut conversion:</tag>TNT provides umlaut conversion if necessary.
    <tag>Remote mode:</tag>Remote users can issue command themselves if
    allowed to do so.
    <tag>Socket mode:</tag>You can configure tnt so that it opens a socket for
    users to telnet to that allows them operation just as you have from the
    console. This is useful where your linux machine is on an ethernet and you
    want other terminal on the net to have use of your radio.
    </descrip>
<p>
DPBOX is a full featured BBS supporting the following features:
<itemize>
<item>F6FBB, W0RLI, TheBox style forwarding protocols.
<item>8-bit transparent handling of messages using AutoBIN protocol.
<item>BBS data compressed to save space on disk, forwarding and downloading.
<item>"Live message capture" off BBS frequency, saves network traffic.
<item>PACSAT style bulletin broadcast transmitter and receiver.
<item>up to 200 simultaneous users.

<tag>Description
</tag>A daemon that will allow you to use your linux machine as an IPIP encapsulating gateway.
<tag>Status
</tag>Ron is running this code himself, and the other version have been run quite successfully.
<tag>System requirements
</tag>KISS TNC, any version of Linux supporting RAW sockets.
<tag>Detail
</tag>If you've ever used an internet gateway from your amateur packet radio you have probably been connected by an encapsulation gateway of some descpription. Most run KA9Q's NOS and DOS, but others run Unix and this daemon. It allows you to encapsulate IP within IP, so that you can 'tunnel' IP connections over the Internet. The software allows you to connect a KISS TNC to your linux machine and to have all datagrams received on it carried across the Internet to a similar gateway. Bdale has installation instructions in the package.
<tag>Where and How to obtain it.

<tag>Author
</tag>Michael Westfall, N6KUY, <mwestfal@.csci.csusb.edu>
<tag>Description
</tag>A split screen terminal program that listens on the ttylink port and
accepts incoming connection requests.
<tag>Status
</tag>Seems to work fine.
<tag>System requirements
</tag>none special.
<tag>Detail
</tag>This is a standalone program that does require you to change the
configuration of your system at all. If you have root access on your machine
then you run the program in a VT or in an XTerm and it will clear the screen
and wait for an incoming connection on port 87 (ttylink). When a connection
is received it will provide you with a split screen display with which to
communicate with the calling person.
<tag>Where and How to obtain it.
</tag>You can obtain ttylinkd from:
<url url="ftp://sunsite.unc.edu/pub/Linux/apps/ham/ttylinkd.tgz"

<p>
<descrip>
<tag>Name
</tag>ttylinkd - a ttylink daemon for Linux.
<tag>Author
</tag>Craig Small, VK2XLZ, <[e-mail]>
<tag>Description
</tag>A daemon to accept a ttylink (port 87) tcp/ip connection and convert it
into a talk request for a user on the host machine. This may also be configured
for use with the <em>ax25d</em> program so that AX.25 users may also make use
of it to connect to you.
<tag>Status
</tag>Alpha, but working.
<tag>System requirements.
</tag>Kernel networking support with AX.25 support if desired.
<tag>Detail
</tag>Because the <tt>talk</tt> protocol is a non-standard, that is it isn't
actually defined anywhere (except the source), the <tt>ttylink</tt> protocol
from NOS has become the defacto standard, at least for amateurs, to provide
keyboard to keyboard communication over tcp/ip. This daemon fills the need
for something to answer ttylink requests to linux machines.
<p>
To build and install the software, I did:
<tscreen><verb>
# cd /usr/src
# tar xvfz ttylinkd-0.02.tar.gz
# cd ttylinkd-0.02
<edited the Makefile to change the SYSOP_USER>
# make
# cp ttylink /usr/sbin
<edited /etc/service, /etc/inetd.conf as instructed in README>
# killall -1 inetd
</verb></tscreen>
<tag>Where and How to obtain it.
</tag>You can obtain the latest version of ttylinkd from:

</tag>A Morse Code trainer that uses the PC internal speaker
<tag>Status
</tag>stable, works quite well, unfinished.
<tag>System requirements
</tag>Linux, any version
<tag>Detail
</tag>Alan wrote this small program in only an hour. It is quite neat,
and allows you to play morse at a range of speeds and frequencies through
the PC internal speaker. You can specify the text to be played either
from the command line, from a file, or the program is capable of generating
random character groups. As it stands you must invoke the program from a
Linux Virtual Console, as it relies on certain kernel calls to produce the
sound, and these don't work as easily from an XTerm. As it sounds each
character it lists the character in verbal form (Di, Dit, Dah etc.) to the
screen. Alan is hoping that someone will take the code and enhance it with
the features he has listed in the comments at the head of the source file.
<tag>Where and How to obtain it.
</tag>I've had a large number of responses from people seeking this code,
so I've obtained Alan's permission to make it available. You can obtain it

<tag>Description
</tag>A clock that will show you instantly what parts of the globe are
exposed by sunlight and what parts aren't.
<tag>Status
</tag>Released.
<tag>System requirements.
</tag>X-Windows.
<tag>Detail
</tag>
<em>sunclock</em> is another of those desktop gadgets that most people
think look nice but really don't have a lot of use for. I use sunclock
to obtain an at-a-glance indication of the time anywhere in the world.
In its iconic form it sits in a small Mercator projection. When maximised
it produces the same image but obviously larger with slightly more detail.
It also displays the date, local time and UTC. sunclock actually calculates
mathematically what parts of globe are sunlit and which aren't, it seems quite
accurate, so long as you assume the earth has no atmosphere.
<tag>Where and How to obtain it.
</tag>I haven't seen any precompiled sunclock binaries for Linux about, so
check your nearest <em>archie</em> server. sunclock compiled straight out of
the box for me.
<tag>Licensing/Copyright
</tag>Public Domain and may be freely copied as long as the notices at the top
of sunclock.c remain intact.

<tag>Description
</tag>A rotating earth for X-windows root window. It has real life shading,
and options for geostatic view, and non geostatic view. A prettier and more
modern version of <em>sunclock</em> but requires a bit more processing power.
<tag>Status
</tag>Version 1.0.
<tag>System requirements.
</tag>X-Windows.
<tag>Detail
</tag>
<em>xearth</em> is a sophisticated program which draws a colour picture of the
earth onto your X Windows display. It offers either an orthographic view as
you would see from space or the map like mercator projection. You have a
number of options in determining the behaviour of the view. The details are
available from the
<url url="http://cag-www.lcs.mit.edu/~tuna/xearth/" name="xearth Home Page">
and in the documentation which is supplied with the package.
<tag>Where and How to obtain it.
</tag>The source can be obtained from its home site at
<url url="ftp://cag.lcs.mit.edu/pub/tuna/" name="cag.lcs.mit.edu"> or just
about any X11/contrib directory.

notice included states that <em>xearth</em> is freely redistributable so long
as the copyright notice is left intact, and be included in documentation.

<sect><heading>How to contribute or update an entry.
<p>
I'd like for this list to be as complete and up-to-date as possible. So I'm
keen to hear about any developments or products that I don't already know
about, or that the entry is obselete or outdated for.

What I'd like as a minimum set of requirement would be something like the
following:

<descrip>
<tag>Name
</tag>The name of the software in question.
<tag>Author
</tag>Who wrote, or ported the software. An email address, or some other means
of contacting them is also essential.
<tag>Description
</tag>A single line description of what the software does.
<tag>Status
</tag>An indication of the software's status. Is it still in testing? Is it a
production release? Is it still in the design stage?
<tag>System requirements
</tag>What does the software require to run? Does it require X-Windows? Does
it need a soundcard? Does it need a certain version of kernel? Does it need
other software to support it?
<tag>Detail
</tag>I'm not keen on including a large amount of detail on each piece of
software as this would consume a lot of time reading and trying to keep up
to date. So instead what I'd like to list is what makes this software unique,
anything special about it. Perhaps its most outstanding features, that sort of
thing.
<tag>Where and How to obtain it.
</tag>If the software is freely distributable then ftp details would be great.
If it is commercial software then the name of the company distributing the
software, and an address or telephone number. If it is available only by some
other means, say mail order, then details on where and how to obtain it.
<tag>Licensing/Copyright
</tag>Is the software Copyleft? Copyright? Shareware? Public Domain? Restricted
in use in any way?
</descrip>

Don't worry if you don't know all of these details, just send me what you do
know and I'll list what I can. I'd rather have an incomplete listing than no
listing at all.

Please mail any contributions to:

<tt><[e-mail]></tt>

I'd list a packet radio address too but I'm still not properly operational
again yet after moving house.

<sect><heading>Discussion relating to Amateur Radio and Linux.
<p>
There are various places that discussion relating to Amateur Radio and Linux
take place. They take place in the <tt>comp.os.linux.*</tt> newsgroups, they
also take place on the <tt>HAMS</tt> list on <tt>vger.rutgers.edu</tt>. Other
places where they are held include the <tt>tcp-group</tt> mailing list at
<tt>ucsd.edu</tt> (the home of amateur radio tcp/ip discussions), and you
might also try the <tt>#linpeople</tt> channel on the <tt>undernet</tt>
irc network.

To join the Linux <bf>linux-hams</bf> channel on the mail list server, send
mail to:
<tscreen><verb>
[e-mail]
</verb></tscreen>
with the line:
<tscreen><verb>
subscribe linux-hams
</verb></tscreen>
in the message body. The subject line is ignored.

To join the <tt>tcp-group</tt> send mail to:
<tscreen><verb>
[e-mail]
</verb></tscreen>
with the line:
<tscreen><verb>
subscribe tcp-group
</verb></tscreen>
in the body of the text.

<bf>Note:</bf> Please remember that the <tt>tcp-group</tt> is primarily for
discussion of the use of advanced protocols, of which tcp/ip is one, in
Amateur Radio. <em>Linux specific questions should not ordinarily go there.</em>
