Some actual data from my 'deaf' receiver.

Formatting is making it harder to see, but N3FL 50 mW signal was 
received from a distance of 725 km.

K5DNL's 5W signal from 2163 km.

This data is freely available on wsprnet.org.

My Mini-Whip is literally a 10 cm wire soldered to the pre-amp board. 
It's an active antenna. These Mini-Whips can be purchased on eBay for as 
little as $15 without enclosure, a bit more with it, and that includes 
shipping. :^)

Obviously for CW, power will have to be higher, but most Topbanders use 
more than 5 Watts anyways.

The point again is, if the remote receiver is in the 'area', it does not 
take much, and with the proliferation of remote receivers, one is always 
bound to be in the 'area' of interest.
