Revision history for FodTrack
=============================
Version 1.0: First release. October '94.
Version 1.1: November '94.
- Dropped support for serial ports (anyway nobody has enough of them...)
- Cured slight instability in the output
- Added support for nonstandard parallel ports at any address
- Increased output resolution to full 8 bits
- Minor changes in appearance
- Added some error handling
- Added rotator calibration command
Version 1.2: March '95.
- Fixed bug with rotator stopping position at north
- Added parameter to disable flipping, for stations without elevation rotator
- Fixed bug in command file reading
- Small updates in the DOC file
Version 1.3: April '95.
- Added Doppler tracking and rig control for the FT736
- Minor bug fixes
- Schematic diagram for the rotator interface is now provided in PCX format
Note: WRONG schematic was distributed with version 1.3!!! If you got that,
delete file FODTRACK.PCX and replace by FODTRK11.PCX.
Version 1.3 beta: May '95
- Added support for IC970 and TS790 in beta status
- Version 2.0 of the rotator interface is now included
- Schematics for RS232 adapters for Kenwood and Yaesu are included
Version 1.4: July '95
- Icom radio support has been tested by IK0XBQ, and Kenwood by IK3NWV
- Added parameter to configure address of different Icom radios
- Added delay for Yaesu CAT OFF command, necessary for fast computers
Version 1.5: August '95
Again a note: I just found out that ALL Fodtrack Rotator controller
schematics distributed with previous versions contain a
silly error: The window comparator reference inputs are
interchanged. This will cause the rotator to oscillate around
the target position. Please DESTROY files FODTRK11.PCX and
FODTRK20.PCX. The former is no longer used (D/A chip costs
too much), and the latter is replaced by FODTRK21.PCX,
included in this release.
- Fixed bug that in some cases caused wrong flipping decision.
- Dropped display of Keps, replaced this by telling how old the Keps are.
- Added display of AOS, LOS and maximum elevation.
- Modified the command help window to make clear that some commands are
only available in manual mode.
- Fixed small bug that caused overwriting on the PPM display.
- Added configuration parameter for minimum elevation at which to track.
- Time is now displayed with leading zeroes. That was a lot of work!!!
- Added step tracking: The program will now update the rotator position
only when the position error exceeds a configurable amount.
- Added antenna parking.
Version 1.6: December '95
The usual note...: Yes, still another bug in the schematic! The power
supply leads to one of the opamp chips in FODTRK21.PCX
are reversed. FODTRK22.PCX fixes this error. By now
several people have built their interfaces according to
FODTRK22.PCX, so I'm quite confident that now there is
no other bug in it...!
- Added support for two separate Icom radios for RX and TX.
- Added a second way for automatization: FodTrack will now read a satellite's
name from the command line, and will exit after a pass, if the proper
parameter is set in the CFG file. The traditional way for automatization
is still supported and recommended.
- The colors are now configurable, making the program usable on some strange
graphics cards which couldn't make it readable before. Also useful for
realizing your very own aesthetic feeling on the screen!
