I called them this afternoon and I was told that the 40 MHz oscillator is normal now, they still have to update the docs. Can anybody comment on my other queries about this device, should I be using it with an LNA or band-pass filter or both or I should have satisfactory results with the upconverter by itself? _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
