consider ST2 Interface
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 PCB was designed on a
PTH PCB measuring 5 x 10cm. Interface
supports Server Easycom.
The Satellite Antenna Tracking
Interface is targeted to interface Yaesu rotators to your PC running
either a NOVA for
Windows or SatPC
Project uses LTC1298
DIP 12bit A/D chip and a
PIC16F84A. Interface takes its power from Yaesu Controller. A
Free DIN8 Plug is supplied with kits/Assembled.
ST3 is preferred for use with G5500 rotor and
is supplied with a 450 Deg Firmware on PIC16F84A.
A few, fully assembled & tested units are
being offered at the moment followed by kits getting ready within a
