Thanks Richard,

Well this may sound odd but I distinctly remember hearing quite a bit of MCW on the HF 
bandds in the 1960s and early 1970s. I think perhaps even hams were using it. I loved how it 
would BLANK the receiver and you could listen to CW with zero noise. Maybe it was all while 
I lived in England growing up though...

Some of my listening was done in those early days in the Cambridge area, using a fine 
Hallicrafters S39 and also with a nice old R1155A receiver.

Both worked exceedingly well for this young SWL designated as "A4941" by the RSGB which 
expertly administered the registration of all SWLs back then!
