I'm finding the uBitx signal/noise ratio on CW to be almost intolerable. ?The background hiss is loud and irritating, and weaker signals get lost in it. ?I haven't tried hardwiring in a narrower filter, but when I plug in a Hi-Per-Mite SCAF from another rig, suddenly the background noise drops way down and signals that I didn't know were there pop out of the background. ?Obviously to be a cw rig, my uBitx will have to have a narrower filter, and plan to install a Hi-Per-Mite SCAF. ?But I'm wondering if others are finding this issue.
