I have always done the same thing with signals at the noise floor, or below. The biggest change I've noticed by doing this is the band noise is much more attenuated through the headphones lying on the table and the signal one is trying to copy jumps out in the clear since band noise is attenuated. 73 Gene N9TF
----- Original Message ----- "Fred Jensen" k6...@foothill.net Related subject: An old CW RO's trick when copying a weak signal in noise and QRM is to lay the headphones on the desk face up. I learned this years ago on the Holy Frequency. I have no idea why it works, but it often does. Maybe one of the acoustic experts here will explain it. 73, Fred K6DGW Sparks NV USA Washoe County DM09dn On 10/14/2016 6:53 AM, brian wrote: > This test may be a bit out of date. > > With digital modes decoding signals ~10 db below the noise these days, > one may need at least two S-units of noise. > > 73 de Brian/K3KO ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to n...@comcast.net ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
