hi, thank you Ralph. It looks like I should have known about not packing two receivers in the same band in the sme box, but anyway, rf parts are not in the same box, and I intended to keep them at the distance of arround 5 to 10 meters. Antenna of 434MHz in is more or less conected directly do the pin, there just matching cuircuit between. The 10.7 MHz out will be with 5 - 10 meters long cable connected with USRP. Power supply of external frontend runs through twisted pair of a UTP CAT 2 cable, which is kind of shielded, and I have a few capacitors on the other end for filtering supply line. As for the LP filter on the 10.7 MHz, i think that LFRX itself has cuoff frequency of arround 50 MHz or so. Will it help a bit if I put some alu plates over WBX board?
