What you *can* do is take advantage of dual-DDC functions, if the two frequencies you want to receive are both within the analog bandwidth of the card, which is typically 40Mhz. There's no requirement that those two frequencies arrive on different antennae--physics doesn't care. -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
