Microhard P900 help

Hello,

I’m Wallacy, and I’m in a brazillian university team of experimental rockets. Few days ago we received as gift 2 P900 (one with enclosure and the other just as chip), and we are having problems to make it work, even after read a lot the given documentation. Could someone help us how to make it work. we are planning to use a 900mhz frequency with adjusted power to achieve different ranges (because we make a lot of different types of rockets) and try to save energy…

Thanks for all the attention.
