Martin, About the 2.7 filters and matching.
I have two of those and they do not match. I set the offset between the two and they are now both 50 Hz off or so :-) . No need to worry about this. In SSB you cannot hear any difference. (It will be a problem with the low bandwidths so if you plan 200Hz 5-poles, then they MUST match. But we are talking about the 2.7s now) I think that you should choose on the filter characteristics, not on the price. The price difference between two 2.8s and two 2.7s (matched or unmatched) is peanuts compared to the K3-rigprice. My choice were the 2.7s because they are actually wider than the 2.8s so I can well listen AM broadcast stations and wide SSB with it, without sacrificing much roofing-effect. In the end, it is your choice. 73 Arie PA3A ------------------------------------- <Snip> The expense on 2 matched 5 pole or 2 8-pole filters is about the same, so the criteria here is performance. May i call for a run-off? <snip> ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
