I: Antenna Pointers



For all the gang, this is my direct answer about the subject.
Friday night, at our local radio club we had a successfull test with this
inexpensive tracker.
At the moment there isn't a PCB, but Vincenzo iw3fol is hardly working on
it, expecially to separate the logical part (PIC, LCD etc) by the power
circuit. In this version the motors are drived by optical triac, but relays
and other device are allowed.
The firmware is able to receive data in EASYCOMM format, and we have
succesfull tested all the stuff with NOVA and Predict.
IMHO Predict is better because is less "aggressive" than NOVA in sending
data via serial line: pointing data are sent only when there is a difference
of 1 degree in azimut or in zenit by Predict, otherwise Nova sends data
twice at second.
Any comments are welcomed.
