I bought the 1.5 kHz filters instead of the 1.8 kHz filters, and I don't find them particularly difficult to tune even in a contest. The key, of course, is to adjust the Shift down to somewhere between 950 Hz and 1050 Hz. The only problem I've ever had with them is that some voices have such an extreme pitch that it is necessary to adjust the Shift for clarity, but that is rarely necessary.
That all being said, I don't think the 1.5 kHz filters provide that much of an advantage for SSB compared with the 1.8 kHz filters. We're talking roofing filters, after all, and generally speaking there are very times that very strong adjacent SSB signals occupy the space between 1.5 kHz and 1.8 kHz AND are clean enough not to spill over into both passbands anyway. I think the great majority of the time the 1.8 kHz filters with a narrower DSP setting would work excellently, and some voices have better intelligibility at 1.8 kHz than they do at 1.5 kHz. If I were buying them again I'd probably go with the 1.8 kHz filters. 73, Dave AB7E >> I find the 1.5 KHz filter to be too tight (I have a couple).
