Hi Larry,

Have you tried the automatic notch filter (ANF button)?  If not, setup
instructions can be found in this document:


If you have set it up correctly and it is not meeting your needs, please
give me a little more detail on the specific situation.  There may not be a
better short-term answer; however, this would be good to know for future

A tunable  variable notch filter for receiving would be nice for eliminating
carriers in the middle of a voice channel. If it is available in PowerSDR I
have not been able to find it.
