Some control units allow you to store only a few channels while others allow you to store a greater variety of channels. Some antenna rotators are powerful enough to rotate a huge antenna fitted to a long mast while others can only handle small antennas.

Once you have the channels set up on your device, you can easily flip between different TV stations with the remote and your unit will automatically direct the antenna in the right direction so you can enjoy a crystal clear view of the stations you want to view.Īntenna rotators differ quite a lot in strength and they come with different types of control units. This rotator allows you to turn your antenna with remote control and it comes with a control unit where you can store various channel settings. When broadcasting towers are based in different directions you may need to turn your antenna on a different channel so you can get a clear view of different TV stations.Ī TV antenna rotator set is just what you need to ease the process of looking for and fine-tuning your antenna every time.

See the downloads page for the manual and HEX files updated 28 Oct 19.Are you switching over to radio broadcasting so you can save money on entertainment and enjoy free TV? One of the most challenging parts of enjoying free TV is to locate the right signal settings and direction for your TV antenna. My system switches higher current so I use relays.

For example if driving a Yaesu G-5500 satellite system you would not install relays and use small signal transistors to switch the logic level in the G-5500 control box. I used 1A output transistors to switch the antennas but depending on your needs these may be small signal types. The main board in the shack unit is shown bottom/left. This suits my supply of parts and my shaky hands with a soldering iron! I have sets of bare boards for sale. The components used are traditional through hole parts. See this page for further information on my Orbitron interface.Ĭonstruction: the boards are double sided, plated through, screen printed. I have developed a capability so that a satellite tracking program that outputs the right data (Az and El for the satellite) will be able to control the beam. All chips are pin for pin compatible, no hardware changes are required from earlier versions. The advantage of the bigger chips is that I have been able to add extra features including a more accurate doppler calculation and add support for the SCA61T inclinometer chip from Version 8.00. The preferred PIC for the shack unit is the 18F4685 (90KB of memory). A similar result to many other tracking programs. The moon calculations are usually accurate to < 0.1 degree but there may be variations up to 0.2 degree. The latter is useful for direction calibration purposes using shadows or sun noise. Because the sun's apparent motion is much easier to calculate, the sun routine produces results within 0.01 degree of the Astronomical Almanac. All the direction control is managed within the unit.

Alternatively this serial stream may connect to the Internet using a WIZ110SR (serial to network adapter) for remote operation.īecause moon and sun tracking software is contained in the PIC© program the system is a self contained unit. A third serial stream may be established with a computer providing information on the location of satellites or alternate Moon information. The 18F4685 in the main shack unit converts the number stream from the antenna to degrees of movement. The shack unit may also talk to a computer or a network. In addition the Shack Unit computes the position of the moon/sun, then decides which way it should turn the antennas to track depending on north/south stops. The AZ/EL boards are polled (9600 baud ASCII) by the Shack Unit to gather the antenna position information. At the antenna the AZ/EL boards communicate with encoders that provide the absolute position of the antenna system. The beam/dish controller unit - how does it work? The project supports a variety of direction encoders including: an AS5040/AS5045 magnetic absolute encoder chip MA3-P12 device and SEI system for A2, A2T from US-Digital HH-05 and HH-12 from DF1SR, Screwjack output potentiometer output 16 bit Gray Coded wheel S CA61T inclinometer chip for elevation and now a magnetometer. The unit supports GPS setting of date/time/lat/long for field work.įeatures are extensive. The project has built in accurate sun and moon tracking, but may be optionally interfaced to a computer for satellite tracking ( Orbitron software) and for EME Doug McArthur’s (VK3UM) AutoTrack software. The purpose of this project is to present a PIC© based project for accurate manual or automatic tracking of a dish/beam.
