Just a curious thought occurred today, why was 87Hz chosen as the frequency for these devices?
I'm wondering if a lot of the 'beating' interference encountered around populated areas could be attributed to the alignment with three phase equipment running at the same frequency and stepping down by 10hz (allowing for bandwidth) or up by 20hz (allowing for the harmonics of the 50hz single phase) would help? or am I thinking too simplistic as per usual :-\
