Oscar 100 narrowband transponder activity

As you know I take a regular peek at activity levels on the narrowband transponder of Oscar 100. It has been pointed out to me that this has encouraged microwave activity especially in Europe. This is certainly true. 

Personally, I was expecting this to become the de facto way of DXing within its footprint. It promised DX, at any time, without QSB with a small fixed antenna (that could even be at ground level) and modest power.  No tower, expensive beams or linear needed!! Very neighbour friendly. 

In my view, I was expecting it to be far busier. When I last looked at European teatime midweek, activity levels were still quiet.
