WSPR DXCC active and needed

When starting with WSPR in 2009 I immidiatly got the  idea to see how many DXCC I could reach with only 1 Watt and a simple antenna. The ultimate goal of course is to reach 100 DXCC. Now, 7 years later I have not reached my goal yet. It seems not to be easy and it's not the propagation or my power. With only 1 Watt I can easily reach all the DX I want around the world even on longpath. I already have proof of that. The problem only is that there are not 100 DXCC on WSPR. That makes this list even more difficult compared to reaching 100 DXCC with 5W QRP or even with QRO. It's a matter of time, sometimes you see a "new" one in the activity list and then you have to be on WSPR and try just like I did last weekend. I'm not on WSPR every day 24/7 like some stations are. It certainly helps if I was. But I don't like the idea of having a WSPR system 24/7, that means you have the system online also when no one is at home and besides that it costs a lot of electricity. For me radio is just a hobby and I don't want to spend money to just keep a system on for just a few more DXCC on WSPR. Anyway, I kept a eye on the activity list and found some stations I need. Sometimes they are on, sometimes not. I still have 19 to go for 100 and I hope I will reach it before I have my 10 year anniversary on WSPR.
