Folks

Current firmware (0.9) is here:

http://www.g6lvb.com/Articles/LVBTracker/LVBTrackPIC16V0.9.hex

I sincerely recommend upgrading any devices with firmware prior to 0.9 - I don't know what or when it happened, but I believe that a COM port driver update over the past year or so within the Windows OS made the RS-232 port speed rather more picky. Due to a schoolboy error on my part, I'd had a bug in there since the year dot that meant the PIC's baud rate generator was loaded with a slightly inaccurate value. This is resolved with the 0.9 firmware release above.

Hello, What firmware version are you running with your LVB Tracker? About 3 years ago users reported about the same problem (chattering relays). They could fix it with a firmware update (version 0.2 to 0.5, meanwhile there are further updates). 73s, Erich, DK1TB

Changing the time SatPC32 to 30sec did not work! G5500 still chatters! _______________________________________________ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.
