It boosts the RF signals from the antenna to the detector, and it minimizes the amount of oscillator RF going back out to the antenna. Again, we hope you'll also look at the somewhat more technical explanation of how your MFJ-8100 Receiver circuit works., Also, most of the time the RF voltage measurement is made on a "sampled" signal via a coupler. This allows the coax to have a straight-line through to the load (Antenna) with very little loss. Since it is sampled via a coupler, you would need to calibrate the voltage readings which usually requires another quality lab style RF voltmeter. - K7PEH., Receiver Sensitivity and Noise. Sensitivity is defined as the lowest power level at which a receiver can detect an RF signal and successfully demodulate the data. Thus, a receiver with a smaller (more negative) sensitivity rating will be able to detect weaker RF signals and demodulate the data. This behavior translates into superior range ..., For example, If putting an AM modulated signal into point 1 that is within the RF range—550 kHz to 1600 KHz for an AM receiver—yields nothing from the receiver's own speaker, but putting in a 455 kHz IF frequency signal passes a tone through the speaker, it is probably that the local oscillator is not running—a fairly common failure., Terminal 1.
