If someone builds a 6m design, 7-element LPF which will fit on the kit PCB, I am happy to stock them in the shop. I think it would be good if someone proves it works first ;-)
One free Ultimate2 kit (or other kits of equivalent value) to whoever proves the U2 works on 6m, and has reception reports to prove it!

I ran a fast 6 meter filter design from the AADE software and put the schematic and calculated plot in my Photos section KE7HR. This might be a starting point.
