Regarding concerns about quality variation in Sangean ATS-909X models, Jay Allen, who posts excellent radio reviews (see link below), writes:
I have now had six ATS-909X samples to check out...three white ones from original production and three black ones from current production. All six have worked properly with no issues and no QC variations I could detect.
However they have made at least one important change with current production and I have also discovered a characteristic which helps explain why different people have such different feelings about its sensitivity. I will be posting a complete update on my site within a few weeks and I think ATS-909X owners will find it interesting.
