The bandwidth in which you’re listening probably is restricted, so you might make adjustments that over-compensate for this, leaving you with too much treble, too much bass, or both! Also, you don’t have the benefit of hearing all the net effects of AGC, etc., like other stations’ receivers, are employing. It’s much better to listen in a separate receiver because that is the only way you can get a “real-world” appraisal of your audio passband characteristics. The first step is to disconnect the antenna on your monitor receiver. You may need to shove a very short piece of wire (an unfolded paper clip, for example) into the antenna jack, depending on the shielding of your transmitter’s dummy load. The objective is to listen to a signal at a level of about “S7” on the monitor receiver’s S-meter. The next step is to turn off the Noise Blanker and any DSP Noise Reduction systems, as well as any DSP bandwidth or shaping features “such as Yaesu’s “Contour” control).
