given area will become major problem espe cially near future last sentence ought etched field box Bob went say AMA estab lished District Frequency Coordination func tion advise members current potential interference commercial transmissions Lets next review RC receivers old fre quencies use before 1983 spaced 80 kHz apart first 11 new frequencies use now spaced 40 kHz apart After January 1991 will have 50 new fre quencies aircraft use spaced 20 kHz apart time spacing between channels nar rows need selective receivers 1991 receiver must able reject adjacent channels 20 kHz awayso dont shoot other down primary use station 10 kHz away can still get Thats FCC gave us 50 channelsto enable us dodge primary guys sounds like 10 kHz selec tivity long shot well does sound way time So what Its pretty obvious need determine channels avoid area conversely appear clear District Frequency Coordinator should able help info make workable system please sure inform Coordinator interference
