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 :) http://dk5ras.dyndns.org/screenshots/ > Cheers, > > Sylvain Ralph. _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
