My TS-440s has a wide band filter that allows almost 6KHz. I'm not a fan of it as there seems to always be images in it but it seems to work fine when I set the rig to 134.630KHz USB. This would place each area of interest at the following in the local passband: HGA22 - 800Hz Local PLC? data carrier thingy - 1044Hzish EU DX - 1688Hz NA DX - 2348Hz DCF39 - 3400Hz 73 Scott Scott Tilley wrote: > Hi Markus > > Wonderful suggestion!
