It would be nice to set up a detailed scientific investigation, however this
would take a lot of organising and time for the analysis.
But we may get  useful information from a simple exercise.

If on saturday April 17 we all received the DCF39 "beacon" at 1200 UTC and
filled in and E-mailed a simple questionaire as below direct to me at
peter.cleall@tms-ltd.com I will do some simple analysis and see if it
reveals anything.


Please send direct to avoid clogging up the reflector.
