Hi Scott! If I understand your question correctly, you have a K3 with the KRX3 sub-receiver installed and now you want to add CW filters for both but are not sure as to whether you should order and/or install matching filters in both. Firstly, the only reason to purchase matching filters at the same time is to insure diversity receive coverage such as low signal work on 160 meters with specialized antennas. If that is not your goal, then it really does not matter. Secondly, matching offsets on CW filters only applies to the five pole filters. (200Hz & 500Hz). If you are purchasing the 8 pole filters (250Hz & 400 Hz), there is a 0 offset so there is nothing to match. Thirdly, you do not have to have the same filters in the Main and Sub-Receivers. For example you could have narrow filters in the Main to allow copying of the DX station and moderate filters in the Sub to listen for the pileup.
I hope this answers your questions. 73, Charles, N2SO On 7/24/2012 10:44 PM, Scott Dunlavey wrote: > going to order some cw filters ... what I would like to do is this... > (with a sub rx!) get 400 Hz X 2... and 200 Hz x 2... my question is, > would it be better to wait on the 200 Hz if I cant get both 200 Hz at > the same time or can I get one at a time... get the other later on... > > > scott > w2ntv > ______________________________________________________________ > 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 > -- Test Charles R Tropp Staten Island NY 10314 USA ______________________________________________________________ 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
