LF,

I have been having e-mail problems and may miss some recent discussions.  
Someone asked me how I could identify a WSPR signal without a decoder:

The times and frequencies of transmission were known.  I saw nothing else 
remotely similar on the band.

The bandwidth was about 6Hz with Argo set to 10s dots.

Posting reports on the reflector elicited confirmation that I was receiving 
WSPR.

PS sorry for terseness.  I haven't been sleeping well and currently feel 
several turns short of a microhenry
