Hi Clinton,
What do you mean exactly?
Do you mean that you will see planes in a wrong position?
That could be.... reason that you have not entered your home position.
Home Position is important for the calcualation of the plane position.
Please give me information what kind of receiver you have, Serial number would be fine. Secondly I would like to know the framerate you receive.
Because of the antenna we have a new one which is working very well with the GNS 5890 and will give you + 10dB. Normally you will see than very high frame rates mostly around 20.000 f/min or higher.
regards
Bernd
