Mission 3 Beholder radio modulation

[WadziuFH]

Beholder (Rockman) 142.3 is on AM modulation, not FM as specified in briefing and documentation, which is weird and confusing because radio automaticaly changes modulation from AM to FM after you change freq from 133 do 142.3. Also kneeboards freqs doesnt specify modulations, its all very confussing
