Add the following: 40m, 30m, 17m, 15m. >30-m, 20-m, 17-m, 15-m >80-m, 30-m, 20-m I don't think those two are good combos without some filter redesign to allow 20m and 30m to share the same low pass filter circuits. Normally 40m/30m share one LP filter section; 20m/17m/15m share another. You'd also have to be careful in re-arranging the capacitors that are switched in the RF and Premixer bandpass filter circuits to support these combos. >80-m, 40-m, 30-m >80-m, 20-m, 17-m >80-m, 20-m, 15-m >80-m, 17-m, 15-m The standard KFL1-4 filter board, *as supplied* from Elecraft, can be built for 40m/30m plus ANY TWO of the following: 20m, 17m, 15m. I've never understood why Elecraft advertises the *standard* KFL1-4 as supporting 40m/30m/20m plus ANY ONE of the following: 17m, 15m. It is a little more versatile than that. I guess the assumption is that no one would ever forgo 20m coverage. That's still no reason to inaccurately describe the technical capability of the standard KFL1-4.
