I am in the process of building a SO2R station and have a question of interstation interference and bandpass filters. I live on a very small lot and have no room for antenna separation. I only have wire antennas and a vertical for 20 meters. I have a set of bandpass filters for each radio. I still get quite a bit of phase noise hash on adjacent bands even with filters. It doesn't seem that the filters make any difference at all ? The biggest reduction in noise is between the dipole antennas and the vertical. Can I ever expect to get the noise to acceptable levels with antennas so close to each other ? Thanks -Joe N3HEE
