2025 ARRL DX CONTEST Phone Nonassisted (Limited) 28MHz at 100W

This is my first post in six months.

Participating in the 28MHz Low power limited category on Phone following ARRL DX CW.

Started at 9:00 AM Japan time.

However, A index was over 30.

I was able to make only 7 QSOs and 3 multis after about 3 hours of operation with a few stations on the Pacific Ocean side.

I thought that the season of 28MHz was finally over.

But I was hoping that as long as the A index goes down, there will be a chance to open it up.

On Sunday morning (22:00 UTC), the A index started to drop slightly, and the East Coast and the Central region started to open.

I was able to recover about 120 QSOs here.

At this rate, I expected that conditions would improve further on Monday morning (around 22 UTC).

As expected, the A index dropped to around 10, and the conditions recovered.

The East Coast stations continued to call me continuously.

However, the Pacific side stations were not as good as expected.

By the end of the day, I had slightly surpassed my top score in Asia last year.

The contest started out as a struggle, but I was able to enjoy it.

I think I will still be able to enjoy 28MHz for the rest of this year.

And since self-spotting was allowed in this contest, I took advantage of it actively.

I think it was effective, because when I spotted it, I started getting called in, albeit only slightly.

2024 ARRL DX CW/PH Certificate

After a series of problems, the ARRL web has been restored and

ARRL contest certificates are now available for download.

In ARRL CW, I was able to contact with many stations, but I could not make JA top.

On the other hand, the PH score was not so good, but

I was able to get the top position in Asia.

Serious Noise to shortwave band

About a month ago, I began to notice noise in the shortwave band every day at irregular intervals. This time, I received the signal in AM mode and recorded the waveform using the IC-7610's audio scope.

Noise peaks can be observed almost every 100ms.

This noise is characterized by alternating occurrences and stops at intervals of several to 10 seconds, lasting several minutes in the shortest case and several tens of minutes in the longest case.

The final results of the CQ WPX SSB held at the end of March are already available.

The tabulation process is getting faster.

I was able to top JA again this year in the 10m band 100W and under category.

The top Asian competitor was VR2T operated by VR2ZQZ and I was 2nd, not an easy win!

2024 WPX contest SSB raw score and posted a videos on Youtube

WPX contest SSB raw scores are now available. 

So far, I am leading among JA in the 10m band Lo power category, but in Asia, I am completely defeated by Hong Kong stations. It is hard to win when they are active participants.

I have posted a video on Youtube showing a scene of contest that I participated from Japan. 

They are audio only, but I would be happy if you could take a look at them.

See you again at the contest!
