121. Re: [TenTec] Orion ll Audio (score: 1): Author: "Ron Castro" <ronc@sonic.net>; Date: Sat, 25 Mar 2006 22:19:21 -0800; Absolutely right, Bob. Throw in some loud linear noise, mic level too high, some RFI, too much compression, and you hear what I'm hearing in the contest this weekend!

Re: [TenTec] Orion II NR Performance Measurements (score: 1): Author: "Ron Castro" <ronc@sonic.net>; Date: Sun, 26 Mar 2006 12:47:55 -0800; I haven't played with the NR much on SSB, but I do notice some bandwidth reduction, but the DE is still there. I does help on CW if you get the RF gain set right. Ron N6AHA __________________________; /archives//html/TenTec/2006-03/msg01164.html (9,925 bytes)
