Should this have been posted on the Flexedge?
Well, I am also having the same problem. I put up a 6 meter antenna today and tuned it to 50.125. At 50.125 the SWR is 1.27:1. So I went up and down and the SWR varies from 1.21:1 to 2.05:1 at 51.400 I changed frequency at .1 intervals. So that 50.015 was 1.21:1, 50.1 was 1.27:1 and so on up to 51.4 was 2.05:1. At each interval the ATU did not seem to do anything. The ATU button did stay "on" but when I pressed "Tune" the SWR would be the same as if the ATU did not match anything. In each case when I pressed ATU the tuner seemed to try and tune, relays clicked etc..., but no match and in each case the tuning failed at about 61% complete. The tuner stayed in "ATU" mode and did not switch back to "Bypass". I am using Win. 7-64 (as Administrator), PowerSDR 2.0.6 and a Flex-3000. I have no experience with the other HF bands because I don't use the ATU. For the other bands I use a Palstar BT1500A balanced tuner. So never tried the ATU before. Don kd6hq Freq.
