That had occurred to me as well, although I notice they are now offering a 65.52 MHz LO[1] and their full SDR receiver box does advertise having a 40 MHz LO, so I presume they have to adjust the high pass filter for those models. The 40 MHz signal comes through quite strongly and is detected by the RTL-SDR. I sent them an email earlier today, I'll see how they respond, maybe it was just a manufacturing issue. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
