[USRP-users] Different behavior in fft window depending on central frequency

Hi all!

I have a B100 with a WBX and a couple of VERT900 antennas.

I'm getting completely different readings in the uhd_fft utility depending
on the center frequency.

For example, if I center at 896M I get a peak at 896.2M. But if I center at
896.3M, the 896.2M peak seen earlier disappears..

Also using the RX2 antenna I always get a center peak, no matter the

Is this normal?
