[TowerTalk] ALFASPID rotor problem....

[ssc]

To be clear the SPX01 serious of rotators in NOT sold be Alfa Radio and 
is therefore not a AlfaSpid rotator.

Not sure which controller you have but it sounds like you have the wrong 
ratio in the controller.  If you have the ROT2Prog - Press the "S" to 
get into the setting for the ratio setting - use the arrow key to change.
