The RF section consists of a Shaded Grid Low Noise, High Gain VHF Tetrode, High Gain Pentode Mixer followed by three Wide Band IF stages, Limiter, Wide Band (0.6 MC) Discriminator and Anode Follower Output. put. 0.95 microvolts, ( 20 db quieting ). 1.9 microvolts. ( 30 db quieting ). 240 KC Bandwidth: 6 db down. 0.6 megacycles. 88-108 M.C. -± 20 KC AFC off; ± KC AFC on. 40 db 70 db Gated beam, constant output. 300 ohms Less than 0,1% IM at 30% modulation. Less than 0.25% IM at 100% modulation. db 20-20,000 c.p.s. including standard 75 microsecond de-emphasis. 60 db below 100% modulation. Within FCC requirements. 1.5 volts for 100% modulation. 5 volts for 30% modulation, AM Low noise, high gain RF pentode followed by a pentagrid converter, two broad band IF transformers, separate tuned AVC amplifier, infinite impedance detector and adjustable 10 KC whistle filter. The separate AVC amplifier circuit avoids overloading of the detector improving linearity. Exclusive noise filter for noisefree long distance reception. 20 microvolts per meter. Terminal sensitivity 4 microvolts. 16 KC Bandwidth: 6 db down. 530-1640 KC 55 db 55 db Built in Ferrite Loopstick with low impedance Terminal for external antenna. Less than 0.8% harmonic. ± 3 db 20-8,000 cycles. 55db below 80% modulation.
