I think the problem is, as you say, the decoder isn't sensitive on weak signals. But what's the point, anyway? There are a number of programs which will tell you what beacon you will hear at any given time, so you don't need to decode it, just know that you heard something.
If you want a record of what's heard use the program Faros. This is much more sensitive than any ordinary CW decoder for this specific task as I suspect that it digs into the noise looking for exactly what it expects the beacon to send.
