[Lowfer] WSPR Weak Sig vs. QRP

[pbunn at patbunn.com]

Don't really want to start an argument. I can sometimes be decoding 4-5 
signals that are running a watt or so ERP and from distances of 
approximately 1000 KM or more. Then the 20-30  watt ERP station comes in and 
nothing decodes again.  I am 1000KM away and he is 20 over 9 on my R75 
running WSPR.

I have plenty of other thing to do on the band  - so I go do them. When that 
station is in the window  - at my location decodes don't happen.

Weak signal and QRP are not necessarily synonymous.  Weak signal
is subjective to the target area for decodes.  Higher ERP can be
more useful for propagation study, ie. observing characteristics
of QSB, where lower power would just result in no decodes during
drop-outs and provide nothing quantitative, but higher power
would potentially show an actual dB variation compared to peaks.
