Nano-40 heard in Holland

I still haven't made a contact with the little Nano-40 QRPP transceiver I made, but after listening on several occasions I finally heard its signal coming back from the Web SDR at the University of Twente in the Netherlands at 2100 this evening.

I sent a few V's and clearly heard them come back with a second or so delay from the remote receiver. I then attempted to send CQ, but the distraction of the delayed signal made it difficult. The signal was lost in the noise some of the time, but at other times it was perfectly clear and readable. I calculated the distance between my QTH at locator IO84hp and the Web SDR at JO32kf to be about 750km or about 450 miles. Not bad for 150mW to an MFJ magnetic loop antenna in the attic! Isn't QRP amazing?

I will treasure the first contact I make with this little radio, so for the time being I am not going to cheat and try to arrange a sked because it would be much more of an achievement to make a contact that happened naturally. But if you should hear me one evening calling CQ close to 7.030 please reply slowly because I can probably hear 4 or 5 different stations at the same time and my CW is not that hot so it will take a lot of concentration for me to read you. A bit more power might help too because the little guy's receiver isn't as sensitive as the one you'll be using.
