W5GI MYSTERY ANTENNA (Pdf)
W5GI Mystery Antenna A multi-band wire antenna that performs exceptionally well even though it confounds antenna modeling software Article by W5GI ( SK ) The design of the Mystery antenna was inspired by an article written by James E. Taylor, W2OZH, in which he described a low profile collinear coaxial array. This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner. It is approximately 100 feet long, can handle the legal limit, and is easy and inexpensive to build. It’s similar to a G5RV but a much better performer especially on 20 meters. The W5GI Mystery antenna, erected at various heights and configurations, is currently being used by thousands of amateurs throughout the world. Feedback from users indicates that the antenna has met or exceeded all performance criteria. The “mystery”! part of the antenna comes from the fact that it is difficult, if not impossible, to model and explain why the antenna works as well as it does. The antenna is especially well suited to hams who are unable to erect towers and rotating arrays. All that’s needed is two vertical supports (trees work well) about 130 feet apart to permit installation of wire antennas at about 25 feet above ground. The W5GI Multi-band Mystery Antenna is a fundamentally a collinear antenna comprising three half waves in-phase on 20 meters with a half-wave 20 meter line transformer. It may sound and look like a G5RV but it is a substantially different antenna on 20 meters. -

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.

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. -

PERPUSTAKAAN UMP 111111111111111111111 0000080238 DESIGN OF AN AUTOMATIC ANTENNA TUNER SITI AFIFAH BINTI HAS SAN Thesis submitted fulfillment of the requirements for the award of the degree of Bachelor of Engineering in Mechatronic '-- -.---. - • I '•'-. I ••••'• ,'•; Faculty of Manufacturing Engiñeering t ri UNIVERSITI MALAYSIA PAHANG - -_J SEPT 2013 VIII ABSTRACT This thesis presents the design of an Automatic Antenna Tuner. Automatic Antenna Tuner is used to improve the power transfer on the transmission line by matching the impedance of the tuner to antenna. It attempts to convert the input impedance to 50 to matching with the antenna impedance. It is also used to control the switching components to load the signal frequency. The objectives of this project are to develop the software system to control the switching components, to develop an LC circuit and to find the best combination of inductor and capacitor to load the signal frequency. This thesis describes the development of the automatic antenna tuner and the criteria needed to develop the equipment. The range of frequency, that the automatic antenna tuner able to load is 3- 23MHz. ix ABSTRAK Tesis mi membentangkan reka bentuk Automatic Antenna Tuner.
