likely become effective around mid-1983 3 FCC will asked leave technical specifications except modulation limita tions equipment type certification currently 4 Existing RC equipment may able used

channels future committee will seek approval AMA Executive Council purchase two experimental RC systems 900 MHz 7 For near term AMA will mount campaign discourage new com mercial radio station applicants using existing seven RC channels 8 A new computer program printout has proposed pinpoint power lo cation commercial radio stations operating present seven RC channels throughout country 9

require frequency change remain legal after 10 year phaseout period present frequencies generally thought peer pressure radio environ mental conditions may force us metropolitan areas change newer technology narrower band receivers smaller clubs rural areas can probably use present equipment indefinitely proposal now has no planned mandated obsolescence Another problem thrashed out consider ably Frequency Committee meeting identify various frequencies flying field decided channel numbers would practical way further combination colored flags numbers would serve us best am pres ently working frequency control system will include ability lock out other frequencies would either cause caused interference due har monics images Eventually radios will probably use IF strip something other 455 KC order eliminate some problems time being will probably use primarily low half roster until new receivers developed 86 Model Aviation hope newsletter editors others smarten up get behind proposal continue talk against it ulti mately denied FCC reason will probably take least four five years get back now proposal increasing interference industrial users frequencies cant wait long endangering very existence RC may dis agree proposal did got six 27 MHz spots instead got 72 MHz obvious pub licity opposing particularly print will have detrimental effect sport general dont like proposal suggest specific changes made NOT want clear channels unhappy committee members petition AMA President change As saying goes Lead follow get H - out way Now bad news Dont look proposal go

likely become effective around mid-1983 3 FCC will asked leave technical specifications except modulation limita tions equipment type certification currently 4 Existing RC equipment may able used
