Any better ideas to > avoid this dedicate beacon? To add a beacon is a very good idea. It can be placed near the band edge where S/N is not so good due to aliasing so it would not disturb signals of interest. By having very good frequency accuracy on the beacon one can synchronize all the dongles to get very high stability and accuracy:-) - leif -
