This afternoon, I was calling CQ on 17 meter CW at the bottom of the band
near 18.068. Lots of Japanese stations were coming in. This morning, on
the other hand, the band was filled with moderate to strong Europeans and
quite a number of them were up and down the band. I have very little line
noise above 80 meters. On 80, unfortunately, my noise runs from S9 to 10
over S9 but from 40 meters on up through 432 MHz, there is little noise, if
at all, and what noise there is, the noise blanker takes care of about half
of it. While calling CQ, as I was saying, on 17 meter CW, a J A called me
but he was right on the threshold of what noise I did have. The noise
blanker helped some but not enough because the signal was weak. So I
quickly snapped on the Digital Signal Processor DSP. The signal popped
right up to a Q5 signal and I worked him without any problems. In other
words, without it, he would not have been Q5 copy. So, at least on my
radio, I have been taking advantage of the DSP often in recent days.
