Subject: [TowerTalk] ALFASPID rotor problem....

Hi there,
First of all MERRY XMAS for all !!!!....I´m using this holiday season to set 
up my new AlfaSpid SPX01 AZ/EL rotor. It´s part of a LEO satellite station 
that I´m building when weather allows.
Yesterday I put the rotor on my workbench and started to test it on azimuth. 
Wiring is correct, power is 13.8v and rotation is smooth. I found out that 
the rotor is missing 25% of its rotation.
Put it on 0º degrees but when it reach 45º, controller says its on 
90º....when it reach 90º it says it´s on 180 and when it´s on 270 it says 
it´s on 359 and stops rotation (got then configured for 360º North stop).
Looks likes it counts 2 pulses for every degree instead of one. The same 
applies for elevation movement. Any ideas???...This is my first alpha spid 
rotor. Happy holiday season.
