|20m without balun|
14.100 to cover the CW and Digi section of the band. The local time was around 22:37 and without Balun Designs 1:1 balun installed the section of 20m from 14.000 to 14.100 showed somewhat I called washout sections. I did notice around the 14.040 mark there is some RFI on the waterfall. When I moved the VFO over to that section the RFI was very faint. Also a very faint indication of RFI on the waterfall just past the

When the 1:1 balun was introduced the band cleaned up regarding the washed out sections. I was able to see Digi signals, in the posted picture the Digi signals are almost gone from the waterfall. There were some CW signals close to the noise floor that I was able to hear (not shown in the picture). I did notice the RFI what was in the waterfall without the balun installed is gone BUT after the balun was installed at 14.080 there was a stronger RFI signal and I could hear it very well when tuned to it. This RFI was not there all the time I would say it was on and off. Not sure what it is but that is not the purpose of this post.....save that for another post.

Because it was later in the evening 40m seemed to really shine when I preformed the comparison with and without the balun installed. The span of 40m was 7.000 to 7.100. Without the balun, there was some CW signals as well as some Digi signals that I noticed. I was pleased with what I saw until I placed the balun in the picture. This cleared up the band and I was able to see more CW signals and the Digi section was much more pronounced. I also noticed according to the S-meter with the balun was around S-4 and without just over S-5.
I am very pleased how the balun has improved the receiving end of things.
