Replacing 1200 Baud AFSK FM with PSK and Deploying DTN Iain Young [email protected]
Replacing 1200 Baud AFSK FM with PSK and Deploying DTN Iain Young [email protected] Agenda ● Introductions ● AX.25 Link Established! ● Exactly What Are We ● Adding TCP/UDP/IP Planning To Replace ? ● Adding DTN ● Why Replace It ? ● Results ● Computer Network Theory ● Conclusions ● How We Replaced It ● Future Experiments – Tools and Utilities Needed ● Acknowledgements – RF Setup and Maps Introductions ● Two major areas of focus – Replacing AX.25 1200 baud AFSK FM with PSK – Deploying DTN ● Who ? – Iain Young, G7III, MAXPAK Chairman – Dave Madew, M0DCM, MAXPAK Committee Member ● MAXPAK – Formed as a dedicated AX.25 Packet group for the Midlands – Constitution changed a couple of years ago, to include all digital modes So What Are We Replacing, And What Are We Not Replacing ? ● The AX.25 Physical Layer – In “Network” Parlance, Layer 1 – We mean the 1200 baud AFSK FM transmissions ● We are not replacing what the network world would call “Layer 2” or “The Data Link Layer” where you send and receive AX.25 frames to and from AX.25 addresses ● The mode we are all familiar with could be more formally described as AX.25 over 1200 baud AFSK FM ● The mode we will be creating could be more formally described as AX.25 over PSK Why Do This ? (1) ● 1200 baud AFSK FM is not exactly well known for it's effeciency, especially with regards to: – Spectrum usage, – Power requirements – Link budget ● Even it's 300 baud cousin is not particularly well thought of on HF, can be improved on and that's only a quarter the throughput! Why Do This ? (2) ● Plenty have claimed -
Overview of Ham Radio Software
OVERVIEW OF SOFTWARE FOR DIGITAL HAM RADIO Where to download free software: (often there are helpful help files also, so you might want to peruse around a bit more than just download) FLDIGI https://sourceforge.net/projects/fldigi/files/fldigi/fldigi- 3.23.15_setup.exe/download https://sourceforge.net/projects/fldigi/files/fldigi/ Downloading FLDIGI can be a bit tricky. Try going to the above page and then selecting (for Windows) the file ending with “setup.exe”. WINLINK EXPRESS http://www.winlink.org/sites/default/files/downloads/winlink_express_insta ll_1-4-2-0.zip UZ7HO http://uz7.ho.ua/modem_beta/soundmodem95.zip is the actual download. SOUNDMODEM.EXE WINDOWS BPQ http://www.cantab.net/users/john.wiseman/Downloads/LastestInstaller/ is the directory http://www.cantab.net/users/john.wiseman/Downloads/LastestInstaller/BPQ 32_6.0.13.1_20160927.exe is the actual download link Malware Detection Software: Many commercial virus checkers and malware detectors will consider very rare software to be automatically suspect, and delete or refuse to run or load it. You will have to find out how to tell your malware detection software to accept these quite- respectable programs. Every malware detection program works differently, so read your instructions! Digital Ham Radio has many facets. Characters from a computer become some version of “tones” going to a transmitter microphone input; audio from a receiver speaker output gets transformed into characters in a computer and possibly visible on the screen to a user. Software & hardware combine to make this magic happen. This paper will attempt to categorize the major software required to accomplish several communications. -

Digital Mode Presentation
Digital Mode Presentation General Knowledge Digital communication is the exchange of digital data over the air • Email, Digital files, Keyboard-to-keyboard (chat), and others Protocols on today’s menu • RTTY, PACTOR, JT9/65, PSK31, FSQCall, Olivia Communication = digital mode if info is exchanged as individual characters encoded as digital bits. Example: A = ASCII 01000001 Some consider CW a digital mode. (an A = di-dah) Some modes are old, like radio-teletype, invented in the 1930’s. Some modes are new, like FSQ, invented in the mid-2015’s. Where? • Look at an amateur band chart (80 meters and 20 meters) • Look at a band plan (2-4, 2-17, 6-2) • Show CW, PSK31 (3.570 & 14.070) and RTTY • Look at http://bandplans.com Definitions Air Link – the part of the communication system involving radio transmissions and reception of signals. Bit – fundamental unit of data; a 0 or 1 in binary Bit rate – number of bits per second sent from one system to another. Symbol – signal characteristics that make up each distinct state of the transmitted signal • CW symbols = on and off • RTTY symbols are tones • Baudot or ASCII (simple methods) encode one bit in each symbol • Sophisticated codes use complex audio signals to carry the data and encode more than one bit in each symbol Baud – number of symbols per second that are sent from one system to another. Duty cycle – ratio of transmitting to total on/off time • Important to know duty cycle of mode because most transmitters are not designed to operate at full power for extended periods of time. -
