And the test didn't include the 22kHz by the Zinwell MS and the modified 0/22kHz monoblock?It's been I while, and I had to read the whole topic again to refresh my memory what this topic was about.Nice to read from you again.  :-)I'm not sure as to the answer to your question (as I indicated earlier), alas. Are your 4/1 splitters completely DC-blocked, or oneway DCblocked?I would expect an slightly attenuated 22kHz signal through those, and interference in the 22kHz signal from the combined multiswitches. But if the 22kHz would be stably blocked by that ~ don't know.Your 0/22kHz switch could be needed again. But that switch might again be confused by the interference in the 22kHz, as in your earlier test.<s>Another option for that may be: a "diplexer" or "UHF/SAT combiner". That combines/splits 0-900MHz from 950-2300MHz, so that port would attenuate the 22kHz even further (don't know if the non-used port should be terminated with an end-resistor). However I don't know if the effect of a diplexer would even be as strong as "blocking" the 22kHz. Would be interesting to see that tested by someone! (Don't know if I could find the diplexer I have stored somewhere, to test this effect....)</s><s>Sorry that I just can give options and opinions to this question</s>. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite73" alt=":unsure" title="Unsure    :unsure" loading="lazy" data-shortname=":unsure" />Edit: No, this would NOT be an option, I think. The satellite port should pass the 22kHz signal, or it wouldn't work properly for satellite. Alas.... I was thinking wrongly...There are "22kHz tone blocking filters" on the market, I just saw on google.Otherwise: I think there are more chances with this option: sacrifice one port of the 4/1 one-way DC-blocked switches (hope you have these?) for the power inserter line, and supply a somewhat higher voltage than your Zinwells give. That way the superimposed 22kHz would never 'win', I would guess, and would never reach your LNB. But... this is just an idea; I've never tested it myself. By the way: LNBs with LOF 10750 are/were used in the USA/ North America (and maybe New Zealand), I read. They are called "standard LNB" or "standard linear LNB" (as opposed to "universal LNB"?). I don't know if they come in dual output versions, or twin versions.Maybe that is of help?Greetz,A33</blockquote>
