*Jack, with respect I would disagree with your assessment of the 1.8Khz filter.
>From experience, I had both the 2.1 and 1.8 fitted and by judicious use of the Hi Cut/Lo Cut adjustment I find the 1.8 far better in practice. Audio quality is easily made pleasant to the ear without introduction of any artifacts that are not wanted and provides a better blocking of nearby strong stations. Many of us have anywhere from mild to extensive hearing issues which vary from one person to another. In my case it is Tinitus and therefore it is essential for me to use a headset and combining the 1.8khz filter with the Yamaha CM-500 I find the audio pleasant. Just last weekend I participated in the VK Field Day contest and spent a solid 24 hours on air with little problem other than sleep deprivation..:-) A quick check of local K3's here in VK4 reveals many are using the 1.8khz filter in preference to the 2.1Khz filter for SSB use. The 400 is popular for CW/Digital use. If your hearing is somewhere in the normal range I do envy you and perhaps the 2.1Khz filter is more to your liking.
