All received datafiles were averaged in 1 minute periods, to surpress static crashes etc... 2. All datafiles were 'shifted' to an average value of -30dB (relative), since all measurements (except for Alan) were relative As a result of 2. you cannot compare the absolute strength of the data, just the trends. Very interesting is the 20 minute 'off period' of CHF just before midnight as this alows to determine the SNR (and that is after all the most important figure in practice). All data are available as an Excel file for those who want to have a closer look, just let me know by (direct) e-mail and I will sent you the file. 73, Rik ON7YD
