I forward to the BB the following message \nfrom Juan Antonio EA4CYQ:\n----------\nHi all,\n\nI have published several articles in relation to ham satellites in AMSAT and \nother magazines such as URE, CQ-DL, Megahertz Magazine and several Webs. \nBut most of them were in Spanish. I have translated them into English, you \ncan find the following issues:\n\n- The CJU antenna. It was designed by EB4DKA and EA4CYQ to improve the UHF \nreception with your HT, it is thought to uplink with your VHF mobile \nstation. You will receive the UHF downlink in the same way a fix satellite \nstation.\n\n- The IOio antenna. It was designed by EA4CYQ to work V/U and U/V amateur \nsatellites with an HT. It has an amazing performance, it is even better \nthan the Arrow antenna in some features.\n\n- A dual band portable yagui antenna. This is a very well known antenna into \nthe amateur satellites world. Here you can find how to build it with normal \nstuff and an impressive performance.\n\n- The EGGBEATER II and TPM II antennas. They were designed by Jerry K5OE. \nIn this article I tell my experience at the beginning in the amateur \nsatellites world and all the vicissitudes to work amateur satellites from my \nshack with the minimal equipment. Here you will find all the details to \nbuild these fantastic antennas.\n\n- The 2.4GHz DISH ANTENNA. Taking advantage of my AO-40 experience I could \ngo more deeply into the microwaves world. Here you can find all the details \nto build two different 2.4GHz dish feed systems, which you will be able to \nuse in wireless terrestrial communications.\n\n- The LINEAR TRANSPONDERS. A lot of amateur satellites use this system. \nThis article will help you to understand how they work.\n\n- HF or SATELLITES?. I try to demonstrate with this article that a \nsatellite fix station is at least as good as an HF station. You will get \nthe same performance with small antennas and low power out.\n\n- The DATA CONNECTOR. This connector has much more possibilities than to be \nhooked to a TNC. In this article I study its features and I propose to use \nit with a PC soundcard, to receive meteorological satellites and I even \npropose to build a cross band repeater. You will be surprised about its \npossibilities.\n\n- CIRCULAR POLARIZATION. If you want to know more about this kind of \npolarization and you want to see a comparative of VHF and UHF circular \npolarized commercial antennas, you should read this article.\n\n- TRANSCEIVERS TO WORK SATELLITES. If you are thinking about setting up a \nfix satellite station, here you can find all the transceivers in the market \nand combinations between them to be successful.\n\n\n- THE EA4CYQ SHACK. Here I describe my shack, perhaps it could be useful as \na reference if you are thinking about setting up one.\n\n- THE EA4CYQ LOG. If you have contacted with my station between June 1.996 \nand March 2.008, here you can find it. It is in call sign alphabetical \norder. We will upload it in the near future.\n\nYou can find them at the following Webs due to the generosity of Pedro \nEB4DKA and Rodolfo EA4CAX:\n\nhttp://eb4dka.laserenadigital.com (also www.eb4dka.tk ). This Web is \ndevoted to ham satellites and Pedro has an impressive collection of photos, \nvideos and interesting articles. He is an authority working in portable \nconditions.\n\nhttp://personales.ya.com/ea4cax/ Rodolfo is specialized in LEO and \nGeostationary meteorological satellites.\n\nO hope you enjoy this articles devoted to promote the amateur satellites.\n\nJuan Antonio\[email protected]\n73s\n----------\nBest 73 from Spain\nPedro EB4DKA\[email protected]\nhttp://eb4dka.laserenadigital.com\n\n\n", "attachments": [] }
