Hi, I misstated: Should have been the best was several hundred HZ away from what I thought was optimum...
I did a number of tests to see what I "liked", vs what was best based on my ear pass-band, (based on the hearing test), my best guess was 680, my best based on ear pass-band was closer to 490. The 490 is far batter than my best guess was. I had actually placed the CW side tone in a narrow -15 db null, almost exactly. I asked the audiologist about that, and she indicated it might be related to me never actually hearing anything much at 680 Hz, and the perception that when I set CW to the null it seemed in the clear for me. I have verified that I copy better at 490, vs 680 Hz, by setting zero and listening to similar stations at high speed and looking at my copy. -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Sat, 2015-02-28 at 14:01 -0800, Phil Wheeler wrote: > Re "I had a hearing test, and the best frequency > was several hundred HZ away from my optimum...". > Best is not the same as optimum?
