I'm currently running two receivers on 20m. One antenna works best east west, the other north south. Despite a noisy suburban location I'm doing extremely well in the distance ranking on http://wspr.pe1itr.com/score.php?band=14 but I feel this might be cheating as I think it's adding the distances when I get two spots of the same station in the same slot.

Should I use a second call or is it ok to run two receivers at the same location?
