Shortwave Receivers. The Hammarlund HQ-100 general coverage receiver tunes medium wave and shortwave in four bands: .54-1.6, 1.6-4, 4-10, 10-30 MHz and 20 meter bandspread. Other enhancements include: antenna trimmer, noise limiter, RF gain, S-meter, stand-by and AVC on/off. This radio does not have a built in speaker.In terms of Noise figure, F = Tn/290+1, F is the noise factor (NF = 10 * log (F))Thus, Y = ENR/F+1. In this equation, everything is in linear regime, from this we can get the equation above. Again, let's use MAX2700 as an example of how to measure noise figure with the Y-factor method.The modulated RF signal is received by the antenna and passed to the RF receiver. a) RF Receiver - The RF receiver consists of an amplifier that amplifies the received signal, a demodulator or detector which extracts the modulated signal from the carrier wave, a modulated signal amplifier and an output transducer.
