Spirit1 - SPSGRF-868 high data rate

Hi,

   I'm working on the module SPSGRF-868 (868Mhz) connected to a PIC24F; the datasheet state that the maximum datarate for FSK is 500Kbps, but after a lot of test I can reach only 100Kbps with frequency dev of 32Khz, channel cut off filter at 200Khz and modulation FSK; every comunication test with data rate greater then 100Kbps and different modulation and freq deviation end with no comunication at all.

Is possible to achive a data rate of 250Kbps or more ?

Thanks.

Just an update, maybe should be useful.

Using a frequency deviation of 48Khz and a channel filter at ~260Khz the system is correctly working with datarate of 250kbps.
