Noise blankers are difficult to design and to use. They work by blanking out the receiver during noise pulses. The user defines what is a noise pulse and how aggressively to blank it by adjusting the NB parameters. If you don't blank out enough, you still hear the noise. If the signal is below

The advantage of controlling the gain manually is not an "old wife's tale". Rather, it's clearly just a technique that is not for everyone. AGC will reduce the gain according to the strongest signal inside the I.F. passband. Manually riding the "RF" gain ensures that a very weak signal is not

Depending the type of noise, for repetitive pulse type noise only,  the Noise Blanker does it job.  Now one must understand that all pulse noise is not alike.  Therefore, different values of NB, both with the  IF values and with DSP values, will require some adjustments.    If the noise is not

Just a couple of points. In the K3(S) there is no "RF Gain" control unless by RF gain you mean "It's not the audio gain gain control." The "RF" gain control operates on the i-f amplifier, which is after the analog noise blanker. In this regard, it is little different from AGC, which operates
