QSO with RU1A with 8 mW

As a milliwatt enthusiast, I often make QSO's with the lowest possible power.
In the IARU HF World Championship 2011 I met RU1A.
Their signal was S⁺⁺+20 dB. Thus S⁺⁺ through a 20 dB attenuator.
When I was answering for the 10th time or more, and my signal was still not heard, I wanted to increase my power. But then I realized (again) that the signal was very, very strong. So I kept answering with 3.6 mW and my perseverance payed off.
He did hear my with 3.6 mW, but he did not copy my call, so I immediately went to 8 mW. Then my call was copied immediately and the QSO was made.

Большое спасибо to the fine operators with their Excellent Ears at RU1A.

This is the card that I received for a QSO with just 1 mW in 2004 .

Sun spots or no sun spots, it is still possible to make QSO's with very low power.
