Now I have geo link calibrated, Now my pitch curves are all wrong. only -1 to =3 on pitch guage. Before geolink I had -7 to =10. do I have to go through spirit system servo center and servo travel after putting geo link on.

Hello,

GeoLink has completely no influence on collective pitch range or pitch curves.
Probably you have only engaged some feature or you forgot about settings in other banks.

Pitch curves are same with or without GeoLink.

I had to go completely through increase servo trave and pitch curves.when I switch from normal to pos hold I only have 1/2 the travel on trans as per pitch guage. What gains are usually used for position hold on trex 600N. thks

Very likely you are enabling Altitude Hold, not Position Hold.

Position Hold is not changing pitch curve at all. Please use default gains first.

no its position hold and I went through every thing and still the same servos twitching and changing pitch while setting on table .disable postion hold pitch is back to normal engage and it act as if it wants to give less pitch for alt compensation. In house on table steady. It says alt .6 to 1.5 mtrs. That's about how high the table and house foundation off ground. Is that feezable.I bought it to use as gps flight as in drone. because stability doesn't do that at all.

Could you please share settings?

I can't help you without any additional information.

Regarding displayed altitude there will be nothing wrong.
