I never suspected that power supply was generating noise. This was a major improvement to my station. I had always had such a high level of noise across 17 meters. The power supply feeding the B radio was causing noise! I checked the other bands and the most significant change was 17 meters. While setting up the 2nd radio, I just happened to be looking at the spectrum display on Radio A on 15 meters when I turned on a DXP38 connected to Radio B and saw this area of noise immediately move on the display. With the spectrum analyzer, I would be able to spot new signals on the band - or at least I think I would. I always start the Roundup on 10 and 15 meters. Since RTTY signals are basically solid carriers, I was thinking the spectrum analyzer would help tremendously on bands with low activity, like 10 meters might be in the contest. It did not quite fit in the slot under the shelf of the operating desk so I had to remove the handle. I have to think the radio had something to do with it. In the following days, I listened for the VU4 stations on CW for many hours without making a contact before the earthquake and tsunami hit Andaman and Nicobar. At Z, I made my first contact with the radio. The first thing I noticed was how well the noise blanker and noise reduction functions worked. Since my office is located in an industrial park, there is a lot of noise. In a couple of hours, by going through the manual and testing the different functions of the radio, I felt comfortable with it right away.Įverything was quite well laid out, the manual was informative and operation of the radio was quite easy.
