END OF PROJECT

 

The ST1 kit/project was designed as an affordable alternative for radio amateurs and schools, to generate interest in satellite communications, and bring space technology into the classroom.  

However, keeping in mind expectations of the many home brewers' who wanted an interface where there was a possibility to "see" Present Position of the Antenna and wanted to know "what is happening between PC & Rotor!!", ST3 was born out of this requirements in mind.

It provides hardware & firmware to interface satellite tracking software with Yaesu rotators, for automatic antenna azimuth and elevation control.

This kit/project greatly simplifies ham radio contact with astronauts on board the International Space Station (ISS), through a program called Amateur Radio in the International Space Station (ARISS). (Detailed ARISS contact and other relevant information about ARISS can be found at: http://www.arrl.org/ARISS/ )

Satellite communication is generally viewed as an expensive endeavor by most hams. Those who buy expensive equipment to show-off their capability further dilute the charm of satellite operation. With some home brewing efforts, excellent results can be achieved at very low cost.

 

Project Bases:  

Project PCB was designed on a PTH PCB measuring 5 x 10cm. Interface supports Server Easycom and Yaesu GS-232.

The Satellite Antenna Tracking Interface is targeted to interface Yaesu rotators to your PC running either a NOVA for Windows or SatPC software.

Project uses LTC1298 SOIC 12bit A/D chip and a PIC16F84A. SMD chip (LTC) will be supplied pre-soldered on all kits and assembled. Interface takes its power from Yaesu Controller. A Free DIN8 Plug is supplied with kits/Assembled.

A few, fully assembled & tested units are being offered at the moment followed by kits getting ready within a month.

It is very important that you study well your Rotor Controller for compatibility with this interface. There are few utilities for Flip operation etc which may be downloaded from this Web page.
