So is the information in the manual just the easy way to set it up, and you can actually put them in whatever slots you want? >From reading the manual I understood that they had to be in decending order starting from FL1, and the filters in both receivers had to match for diversity receive.

You can put your widest filter in FL1 and install them from there in descending bandwidth. Use the K3 utility to set up the filters, much easier than doing it with the config menu. The radio automatically switches in the matching filter that matches WIDTH going down. This will be done separately in each RX regardless of what filter slots were used. You do not have to make slot assignments identical. 73, Guy.

Im populating the roofing filter slots in both receivers with matched filters, and the question came up: When the K3 automatically selects the correct roofing filter to match DSP filter bandwidth, does the K3 do this by filter bandwidth, or by FLx number? > > In other words; when I use the width control, and decrease DSP bandwidth from 3.0 Khz to 2.0 Khz on the front panel, the K3 switches from the 2.8 Khz roofing filter located in FL3 to the 2.1 Khz roofing filter located in FL4. With the sub-receiver on, and in diversity receive, does the K3 switch the sub-receiver roofing filter from FL3 to FL4, like the main, or is it smart enough to know that my sub-receiver has its 2.8, and 2.1 Khz roofing filters in FL1 and FL2 respectively? Does the K3 select the correct roofing filter by bandwidth, or by FLx number? Is the selection logic the same for main and sub-receiver? > > > > > > The KRX3 manual is a little foggy on this. It says you have to have at least one roofing filter, and if that happens to be the KFL3B FM filter, it MUST be in the FL1 location. It also says that you must have the widest bandwidth nearest FL1, but does not say it must be located at FL1. > > > > > > Bill, W7QQ > ______________________________________________________________ > 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 ______________________________________________________________ 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 ______________________________________________________________ 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
