Thank you Howard...
Suggestion for the AMSAT LVB Tracker Team; perhaps on future versions of the assembled kit you might provide a MAX232 chip as a spare part on the USB models. The USB daughter board needs to be removed and the MAX232 inserted for reprogramming the PIC as all documentation suggests USB programming is not reliable.
If anyone has successfully reprogrammed though the USB, please let me know and I'll try it.

Folks
A few weeks ago my attention was drawn to a compatibility problem with Nova and the LVB Tracker 1. I believe that I have found the fault, but it is not clear why it has taken so long for this problem to occur, especially as Nova has been my tracking program of choce for many years! It may only affect more recent versione of Nova.
I have adjusted the LVB Tecker's Baud Rate Generator slightly to be much closer to 9600bps. I must have made an error in my calculations all those years ago, so it was only operating at 9259bps. I have adjusted the BRG by one to make 9616bps and things seem to be much better now. Technically, we were only 3.5% out anyway which normally would be OK (ISTR that 5% timing error is the limit).
Anyway, new 0.9 binaries and source here:
