Radiation pattern after adding radials.
The other day, I battled the heat and installed more radials for my Hustler 4BTV. I have an extra 14-gauge wire left over from when I first installed the radials, and for some time, I was planning to install the remainder, but never got around to it. Well, it is now done, and I am about 15 radials richer, bringing the total to close to 40. After the install, I was wondering if my radiation pattern has changed at all? I connected my WSPR transmitter over the period of 24 hours. For some reason, when I set it up, it was only sending signals out on 20 and 40m. I found out I neglected to save the settings, and the 20m and 40m setup was from the last time I used it. So I only have at this time data for those two bands.
Below are the patterns before the radial additions.

Can you see the issue?
Have a look at the above picture and see if you can see an issue? I operate SO2V in contests now, and this shot was taken during the RAC Canada Day contest on July 1. Operating SO2V is new to me, and I am still getting used to things. If you are familiar with the Icom 7610, you may see the issue in the picture.
Now that you have looked at the picture, let me tell you what I did.....Since I am new to SO2V, I have been trying to get used to VFO A sound in my left ear and VFO B in my right ear. At this time, I had been listening and operating on 15m but just had 20m up on the screen with no audio. Things started to pick up on 20m and drop off on 15m. I then pressed a key on my keyboard (Pause key), and this put me back on 20m and set up N1MM+ to log contacts on 20m.
The odd thing was I was calling CQ contest on 20m for about 5 minutes and no answers. I could hear a noise floor, but I was not getting any replies to my CQ. Then it clicked, I looked at the radio and forgot to take VFO A off mute! The orange light you see in the picture on the main VFO AF/RF control means the audio is muted for the main VFO. I was hearing VFO B in my right ear but I did not click into that. Who knows how many ops called me, but I just could not hear them as the audio was muted. Live and learn, I guess.

Hustler 4BTV cleaning event.
My Hustler 4BTV has now been up for 5 years and is serving me very well, I might add. I felt it was time to take it down and clean it. I know, as Murphy would have it timed that something went wrong and it would be the middle of winter on a very cold and windy day. The items I used were a wire brush to get inside the tubing to clean, 99% alcohol for cleaning and a roll of 3M 33+ tape. This tape has a good temperature range. Finally, a Scotch Brite pad....which I never ended up using. I had read online that it was great for cleaning the aluminum tubing....found out not so much. It has been retired to the kitchen for pots and pans.
My plan was to take each section apart and clean it, and then back together again. I did not want to get too far ahead of myself by taking the whole antenna apart. Before taking a measure section of tubing apart, I measured it and also marked the tubing with a Sharpie marking pen. I wanted to take a measurement and mark it down just in case I removed the Sharpie mark while cleaning. Oh, speaking of cleaning, I thought the wire brushes would be great for cleaning the inside of the tubing, BUT....the 4BTV tubing is 1 1/4 diameter, and I used the 1 1/4 wire brush. The brush went into the tubing just fine, but the bristles refused to go in the opposite direction to bring the brush out! It did take me some time, but I did get the brush out and lesson learned. I used the 1-inch brush instead, which did a great job. All the traps looked great and were still nice and clean. The lower section of the tubing support needed some cleaning, as well as the section of tubing. Overall, for being up 5 years in the ocean air, the antenna looked great. The spider arm required the most cleaning, and I did find a broken spider arm. I do have replacements that I needed to drill a hole in, as I figured some time ago, the spider arms are the weak point of the antenna.
