Linux HAM-HOWTO, Amateur Radio. Terry Dawson, VK2KTJ, terry@perf.no.itg.telstra.com.au v2.3, 1 April 1997 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. 1. Introduction. 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. 1.1. Changes from the previous version Additions: Added entry based last updated field. bpf - filter calculator BayBox - Packet BBS digiinfo - digipeater information database Contest logging program Chirp contest logger bip pileup twclock DX Cluster watcher F6FBB BBS Corrections/Updates: Changed all ftp: url's to point to the directory rather than the file. CLX, and just about everything else. Updated location of John Gotts mirror. ToDo: find a way of automating this, or find an alternate means of presenting this information. 2.

SatTrack - Satellite tracking program Name SatTrack Author Manfred Bester, DL5KR, manfred@ssl.berkeley.edu, (510) 849-9922 Description Satellite realtime tracking and orbit prediction program with X11 color graphics. Status Version 4.0 is a fully commercial release. Version 3.1.5 is the last freely available release. Updated 01 Apr 97 System requirements A vt100 terminal and or X11 server. A Maths Coprocessor is useful, but not essential, for good performance. Detail 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. 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 5MB 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 SatTrack WWW Home Page . Where and How to obtain it. The commerical version of SatTrack can be found at: SatTrack WWW Home Page . The free version of SatTrack may be found at: ftp.jvnc.net or ftp.amsat.org . Licensing/Copyright The software is Copyright of Manfred Bester.

Magliacane, KD2BD, kd2bd@amsat.org Description A satellite orbital prediction program that also tracks the sun's position to predict visible satellite passes. Status Complete and working. Updated 01 Apr 97 System requirements 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. Detail 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. 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.

CLX Packet DX Cluster Program Author Franta Bendl, DJ0ZY, and Bernhard ("Ben") Buettner, DL6RAI, root@dl6rai.muc.de Description A PacketCluster like system running on Linux. Status Current version 2.07 Updated 01 Apr 97 System Requirements Linux Kernel version 2.0 or greater, TCP/IP networking, SysV IPC. Also requires Perl and optionally Expect. Detail PacketCluster nodes have been available for about seven years. The original software was written by Dick Newell, AK1A, and is running under DOS. CLX 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 CLX. So it fits well into an established network of PacketCluster nodes. CLX 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: · It is fully compatible with the internal PCxx protocol and from a users point of view. It allows multitasking and different priorities. · The software detects looping DX spots without generating endless messages. CLX 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". CLX knows of so-called "active" and "passive" links. The outcome is that more DX information is seen by CLX users. · An interface for extending CLX with your own programs and applications. · Extended connectivity through the use of connect scripts. CLX now can build up and maintain virtually any connection using TCP/IP, UUCP or any other communication programs. · CLX uses modern programming concepts like shared memory for common data, lex and yacc to implement command language, shared libraries to keep binaries small, remote procedure calls for interprocess communication. It is strictly modularized with its own dedicated process for every major task. · Comprises of several modules running as separate processes. Where and How to obtain it You can obtain the software from ftp.funet.fi There are five files that make up the package: 00Index clx_206.tgz clx.txt README Licensing/Copyright CLX (c) by Franta Bendl (DJ0ZY) and is available for non- commercial use, but the authors want to keep track of who is using their product, so before you can actually use the software you have to ask for an encrypted callsign string to be placed in the configuration file. You must send mail to clx_us@dl6rai.muc.de to organise this. Contributed by Bernhard ("Ben") Buettner, DL6RAI 5.16. DPTNT Terminal and DPBOX BBS package.

Status Stable and working. Updated 01 Apr 97 System requirements TNC supporting WA8DED hostmode or KISS protocols. Detail 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: Multiple sessions: 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. Data capture, file transfer and logging: 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. Remote Shell operation: 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. Redirection of devices to a channel: TNT allows you to redirect input/output from a channel to a device, a modem for example. Umlaut conversion: TNT provides umlaut conversion if necessary. Remote mode: Remote users can issue command themselves if allowed to do so. Socket mode: 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. New versions will support the Linux kernel AX.25 code. DPBOX is a full featured BBS supporting the following features: · F6FBB, W0RLI, TheBox style forwarding protocols. · 8-bit transparent handling of messages using AutoBIN protocol. · BBS data compressed to save space on disk, forwarding and downloading. · "Live message capture" off BBS frequency, saves network traffic. · PACSAT style bulletin broadcast transmitter and receiver. · up to 200 simultaneous users.

Author Mike Westerhof KA9WSB (original code), then Bdale Garbee N3EUA (port to BSD), then Ron Atkinson N8FOW and John Paul Morrison (port to Linux), then Bdale rolled it all back together again. Description A daemon that will allow you to use your linux machine as an IPIP encapsulating gateway. Note, this probably isn't necessary any more in most installations because recent kernel support a kernel device to perform encapsulation. Status Ron is running this code himself, and the other version have been run quite successfully. Updated 01 Apr 97 System requirements KISS TNC, any version of Linux supporting RAW sockets. Detail 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. Where and How to obtain it. This software is available from the col.hp.com ftp site. Licensing/Copyright etc. Freely distributable, though Bdale asks that if you use the code and like it you might send him a QSL card or a postcard.

Michael Westfall's TTYLINK Daemon Name ttylinkd - a ttylink daemon for Linux. Author Michael Westfall, N6KUY, mwestfal@.csci.csusb.edu Description A split screen terminal program that listens on the ttylink port and accepts incoming connection requests. Status Seems to work fine. Updated 01 Apr 97 System requirements none special. Detail 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. Where and How to obtain it. You can obtain ttylinkd from: sunsite.unc.edu or ftp.ucsd.edu . Licensing/Copyright Unknown, presumed freely distributable. 5.22. Craig Small's TTYLINK Daemon Name ttylinkd - a ttylink daemon for Linux. Author Craig Small, VK2XLZ, csmall@triode.apana.org.au Description 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 ax25d program so that AX.25 users may also make use of it to connect to you. Status Alpha, but working. Updated 01 Apr 97 System requirements. Kernel networking support with AX.25 support if desired. Detail Because the talk protocol is a non-standard, that is it isn't actually defined anywhere (except the source), the ttylink 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. Where and How to obtain it. You can obtain the latest version of ttylinkd from: sunsite.unc.edu or ftp.ucsd.edu . An slightly enhanced version of this software is now included in the Linux AX25 utilities package.

Author Alan Cox, GW4PTS, alan@lxorguk.ukuu.org.uk Description A Morse Code trainer that uses the PC internal speaker Status stable, works quite well, unfinished. Updated 01 Apr 97 System requirements Linux, any version Detail 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. Where and How to obtain it. 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 from sunsite.unc.edu .

How to contribute or update an entry. 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: Name The name of the software in question. Author Who wrote, or ported the software. An email address, or some other means of contacting them is also essential. Description A single line description of what the software does. Status An indication of the software's status. Is it still in testing? Is it a production release? Is it still in the design stage? System requirements 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? Detail 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. Where and How to obtain it. 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. Licensing/Copyright Is the software Copyleft? Copyright? Shareware? Public Domain? Restricted in use in any way? 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: terry@perf.no.itg.telstra.com.au I'd list a packet radio address too but I'm still not properly operational again yet after moving house. 15.
