Adi, How much you can "fool" the offset depends on the filter bandwidth. 70 Hz is a small percentage (2.6%) of a 2.7 kHz bandwdth - you will hardly notice the difference, and if you do, you have very good ears, or are using instruments to measure it - most of us simply use our ears for SSB.
For a 400 Hz filter width, 70 Hz makes a big difference (17,5%), so if you want to operate diversity mode with narrow CW filters, it is best that you have them matched or use only the 8 pole filters. 73, Don W3FPR On 4/13/2011 8:07 PM, Adi Andrei wrote: > I have the 5 pole 2.7 filters for main and sub RX. > One filter offset is -.94, the other is -.81 > In order to do diversity receive, I have to set them both to about -.88 > > My question is: what happens when you set a filter offset differently than > the one specified (as in my case) ? > How is this supposed to influence operation (normal as well as diversity > mode) ? > How can things be improved, short of buying new filters? > > Thank you, > > Adi > 2E0TTX > ______________________________________________________________ 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
