Dear all

Actually it took me quite a while to decipher Rogers callsign and in 
doing so it occurred to me that 500kHz in the day is a good band for 
testing DSP noise reduction as it is noisy but the groundwave is very 
constant.
I did just that with the FT1000 here and found that none of the four 
noise reduction options helped. What did help was the 60Hz DSP filter. I 
estimate that it gave between 1 and 2dB improvement over my ears which 
was just enough to lift the callsign from unreadable to just readable 
(with difficulty). I have never been able to do that sort of test as 
easily on the other bands.
