WSPR discusion on EHAM And still copy WD2XSH/17 @ 0.495890 MHz

I recently posted my enthusiast article about using   WSPR  when i am not in the shack or even not at home.
I got a lot of response some positive reaction even...


It seems that WSPR  is not so well known .
some HAM's  where afraid that there would be an invasion of QRM of Robot stations when everyone would use this like i do 24/7/365..
And they where wondering how much radio spectrum would be used ... although I just explained 200Hz band-slots...
Reading and listening is not as easy as it seems.

Although  i explained  briefly  WSPR  is using a very small band slice 200Hz and low power, still  the old packet radio QRM  stories came up. Some HAM  possible did confuse WSPR with other DIGI modes that are not as silent and effective in power and frequency use. 

Operating a radio unattended is not allowed in USA at some or all? frequencies.  But it can be controlled remote if necessary.
Mainly the pain was about the 7040kHz .
QRP operations could be QRM'd..  
But how many QRP stations actual…
