Dear allActually 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. 73 Richard G3CWI |
