ADUCRF101QSP1Z at 865Mhz

Hi,

  I have EV-ADUCRF101QSP1Z. We have requirement to run our modules at 865MHz. Can I do it on this board by modifying the frequency from software alone?

I understand this board works optimally at 868MHz. Will the radio performance be degraded greatly at 865MHz for this board?

Thanks and regards,

Vamsi
