Mal,

Whilst agreeing with you that QRSS or CW can be copied by most people on= the LF bands, with WSPR you get an immediate S/N report via the internet database, which proved very= useful to me on 500kHz earlier this year.  It helps to see any impro= vements that are made dB by dB with great accuracy.

Of course, you're correct that it needs a decent number of people on WSPR= for this to work. I can only hope that more people give this excellent mo= de a try on 136kHz in the coming months.
