I've seen discussion about the possibility of building a 160M QDX-M... But haven't found anyone that's documented doing it, other than Hans saying he ran some WSPR on one?
I see filter values for someone's 2200m build, but curious if anyone has done a 160m QDX-M build, and if they could share what they worked out for BPF and LPF values?
