Yep, just wanted to mention it

I played a bit more, and I found that checking the iq balance option makes 
things worse, not better. Maybe the real huge center DC peak is too much? 
Without iq balance checked it looks so far OK, much better than without the 
adjustable filter, and the previously mentioned situation around 800 MHz is a 
bit unfair - I found that right below the LTE band there is a strong 785 MHz 
DVB-T transmitter that mixes things up a bit. Outside the GSM 900 and 1800 
bands the spurs (spurs? Signals almost as fat as the original ones!) seem gone 
with properly adjusted filter.
 
Here some screenshots, taken with 10cm of wire directly plugged into the 
bladeRF; sitting on my table :)
