Another one that Fred K3ZO (many time winner of Dayton CW pileup contests) recently mentioned is using extremely low pitch for weak signals. Fred said many commercial ops he knew used somewhere in the 2-300 Hz range so he thought his favored 400 Hz was rather high! I discovered this myself many years ago using the TS-930S which had a continuously adjustable pitch control down to zero! I found 240-270 Hz worked well for weak signals buried in noise on 160m. My hearing is excellent at all frequencies so this is not an issue of hearing loss but simply something I discovered works well for me. Low pitch does not work well for pileups or contests where there are many signals. For those I prefer 400-450 to better catch off-frequency callers, and shift 150-200 Hz on the low side of the center of the passband. Then I can hear most callers pitched at 200 Hz and up. Another thing K3ZO does is to use a wide filter (~1 kHz) and let his ears' 50 Hz DSP filter do the work. I haven't yet mastered that in a contest like the CQ 160! I'm getting by with the K3's lower pitch limit of 300 Hz but hoping for lower some day! 73, Bill W4ZV P.S. Any others...especially from ex-commercial ops? -- View this message in context: http://www.nabble.com/VP6DX----the-true-story---tp15957849p16033692.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
