Dec 21 2019 Yaesu Azimuth and Elevation Rotator Yagi Antenna Cross Polarization Right Hand Polarization TAPR Tucson Amateur Packet Radio AMSAT GEO31 Satellite need reference 8051 Processor IBM Clone Computer Kenwood TR751 Transceiver Yaesu FT 790R MK2 MFJ 1278 Technion University Amateur Digital Satellite Television QO100 Qatar Es Hail Satellite AMSAT DL Some of you know at Field Days past we have used my single 2m 440 beam with a simple azimuth rotor to track the satellites. A very fine antenna used until 1995 48 foot diameter dish two views built refurbished from government surplus see QST May 39 96 in 1995 by N2IQU. This rotor system is available in several Performances SPX 01 Standard version AZ amp EL rotation Resolution 0. 1 Options gt CAT to Radio OmniRig gt OmniRig Settings. 41 W2IMU feed for 23 cm and switchable dipoles for 70 cm. A M2 2M9SSB 9 element Yagi 14. Dec 20 2012 Azimuth and Elevation rotation Tests compared to the single element 20 10 meter loop amp 17 meter elevated fed ground plane with 45 deg sloping radials. com is an archive of Rod AC6V 39 s webpages and is no longer being updated. Manuel has also created a blog post about his antenna rotator which includes a full parts list and a link to all the files. PstRotator includes automatic tracking for satellite or EME communications and some well known loggers are supported Moon tracking WSJT Z Track Trak_SM GJTracker EME System This weekend following the acquisition of some fibreglass poles at the Rosmalen hamfest I decided to set up my bayed 144 MHz beams with the azimuth elevation rotator. Rotator Yaesu GR 5500 Azimuth and Elevation rotator to allow Satellite Operation if required Digital Modes 3Ghz DualCore PC with 2Gb RAM and 560Gb HDs running various programs you will find mentioned on this web site Digital Interface from PC to and from radio ISOTERM USB from G3LIV Cheap. To use a 4 conductor Rotor Control cable and control 2 axis of rotation requires some form of programmatic control at the rotor units. To mount antennas on the rotator two identical flanges are provided at both ends of the elevation polarization axis. The azimuth drive is a HyGain Rotobrake 400 modified for selsyn readout as per the system devised by Vince Vargas W7JRF 8. I wanted to check it and get it ready to be at hand for when I am at the construction assembly stage. b. At 5 degrees above the horizon the first carrier was heard. On the left is a machined aluminum adapter to allow the 3. This interface was rotor moves at about the same speed as the libration fading. Azimuth elevation antenna rotator The rotor was a Yaesu G 5500 AZ EL rotor in order to rotate the dishes to a totally horizontal position in order to reduce dramatically the wind load when in transit. Move the elevation to zero degrees. C 964. This interface was implemented on an azimuth elevation satellite tracking system made from ORBIT 360 TV antenna rotators but the same approach could be used to provide a computer interface on any antenna rotator system that uses a potentiometer for positioning feedback3including the Yaesu G 5400 5500 5600 units. For start ers we need a simple reliable fixed an tenna or set of antennas to see if we really want to pursue this aspect of Ama teur Radio to its limit. With the bit of a blunt pattern due to the last 2 directors being longer that they should be it allows me to just be close and not dead on the bird. Azimuth Pattern Radiation pattern of the antenna when viewed from above. indd 2 30. I do use the interface to control my Yaesu G 400 Azimuth Rotator. Sun 2nd Jul 2017 11 43 9 Abdel then set up his own satellite station which comprises a Yaesu FT 847 with a 5 element horizontal polarised Yagi on 144 MHz a 6 element vertically polarised Yagi on 430 MHz and a Yaesu G 5500 Azimuth Elevation rotator. 86 . Homebrew Antennas for The ACT Meteor Showers VHF Propagation Depending on WX EWWA Countries List Homebrew Az El Rotator Do you think to rotate a Satellite Antenna array in azimuth and elevation costs and arm and a leg Think again. Updated 2020 01 01 nbsp Azimuth Elevation Rotator for Arrow Satellite Antennas. Azimuth Rotator with omni. All I needed was a plate welded to a short mast pipe to attach to a rotor. You can choose between Azimuth and Elevation If you want to start and stop smoothly if the rotor allows rotation of more than 360 degrees if the center of the rotor is North or South etc . We also added a Yaesu GA 300 Shock Absorber Mount to the azimuth rotator. 7 Nov 2012 Set of two M2 rotators OR2800P used for azimuth positioning and of these rotators is the ability of tracking objects both in azimuth and elevation planes. exe v. Much of the design effort was in the software that controls the system. We re hoping that the weather will cooperate and enable us to get these steps completed during this winter. Azimuth AZ Elevation EL Satellite Rotor Controller for Ham Radio. As on the original Texas Potato Masher no elevation rotor is employed. homebrew azimuth elevation rotator
