You want to cut the filter out of the path, but you don't want to cut the main signal path.

The filter affects both TX and RX, but not the auxiliary RX path (RX2). If you just want to receive, use the 2nd SMA port and make sure to set that in the software. If you want to bypass the filter for transmit, you will need to put a cap of about 50 to 200 pF in the path, and cut the traces to the filter.

Hi all, Does anybody know if the ISM filter on the RFX900 board affects both the Rx and Tx paths or only the Rx? Is there a easy way to disable it? Thanks for your help! ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
