CQ WW DX CW 2025

In the CQ WW DX CW contest 2025 I used my new FT-818 for the first time.

I had great fun with low and very low power. 
To work with very low power I use the PA1B 10 dB attenuator behind my QRP set.

I made a total of 83 QRP QSO's.
On Saturday, I started late and made 6 QSO's in half an hour, using an output power from 98 mW to 5 watts.

On Sunday I started on 7 MHz with 5 W. Then I went to 20 m.
Propagation on 14 MHz was good, so I started a series of QSO's with 98 mW.
Later I used 98mW, 250mW and 980 mW alternately.
In the last half hour of my activity, I returned to 7 MHz.
There I made 6 QSOs at 5 watts.

The Table


The DXCC countries in the table are partly in alphabetical order. At the top are the DXCC countries with the lowest power (98 mW from 9A till YU). Followed by DXCC countries with more power.

The QSO with Kazakhstan (UN) is special, because of its low power.

Patience and perseverance
I sometimes have to call 5 times before I am heard.
Especially when it's busy on the band.
Then it's very tempting to increase the power, when I am not heard.
I often must wait until the frequency is absolutely clear. Hi.

43 dB Attenuator built by Kees PE0CWK

I met Kees PE0CWK on a meeting of the Benelux QRP Club in Harderwijk. 

He has successfully built the PA1B 43 dB Attenuator.

When Kees showed me his 43 dB attenuator, I took a few pictures.

Kees tolt me that attenuator works great and is very pleased with the attenuator.

I made photo's of Kees and his attenuator.


43 dB Attenuator built by Kees PE0CWK

The PA1B 43 dB step attenuator is a very accurate attenuator.
Built with good available resistors from the E12-series.
The attenuator is built with carbon resistor of 2 W and 400 mW.
