Antenna...solve one problem only to create another.

 The antenna I have is the Hustler 4BTV, and I have owned it for about four years. I had been noticing that after a couple of days of rain, the SWR on 15 meters would increase.As the weather warmed up, the problem disappeared. My suspicion was that water was making its way into the 15-meter trap and causing the SWR issues.

I waited for a forecast of a few nice, dry days before taking the antenna down for inspection. The first thing I noticed was that I had accidentally covered the drainage slots at the bottom of each trap with electrical tape. If water was getting into the traps, those slots were intended to let it drain out. My first course of action was to remove the tape from all three traps.

RFI is either giving or receiving.

 

Without any RFI issue. 

In my last post, I was on the receiving end of RFI—you can read about that HERE. This post is about being on the other side of the equation: being the source of the RFI.

RFI found and removed

Where we live, I have a very quiet noise floor and have enjoyed it for years. Recently, however, while operating on 40 meters, I noticed an offending signal on the Icom IC-7610 waterfall display. The noise repeated approximately every 15 kHz. If a CW signal happened to fall within the hash, I was unable to hear it.

CQ WW WPX CW results

 

This CQ WW WPX contest was my first major contest in a few years, as we are usually away on vacation and I end up missing it.

This year, my best bands were 20m during the daytime and early evening, before moving over to 40m later in the evening. Overall, the early evening and nighttime hours seemed to be the most productive, with both 20m and 40m really opening up.

During the daytime, I just could not get a good run going. At times, it felt like I was simply calling “CQ Contest” into the ether with very little response. Because of that, this contest turned into mostly search-and-pounce for me, with only the occasional attempt at running.

Throughout the daytime hours, I kept VFO A on 20m and VFO B on either 15m or, at times, 10m, constantly watching for openings. When conditions looked promising, I would jump down to those bands and was able to pick up additional contacts on 15m and 10m. Most of my 10m contacts ended up being with South America.

One thing that definitely kept me in the radio chair was the weather. It was quite chilly here, with daytime highs reaching only 8°C and evening temperatures dropping to around 2°C. In fact, I even had to break out the portable heater I use to keep my hands warm. I find that when my hands get cold, they just do not work as well on the keyboard when entering call signs and serial numbers.

This was also the first major contest for my new Icom 7610, and I am happy to say it performed flawlessly throughout the event.
