My ears are still ringing from the noise i had to endure while waiting for K4M, 3D2,3D2C to come out of the noise on 160. Hours were spent to no avail. But its just bare physics.

Another frustrating experience led me towards some more thinking about why some signal seem to take a deep dive on the "last mile" and become inaudible.

Topband: one way prop (score: 1): Author: <df2py@t-online.de>; Date: 11 Nov 2007 12:00 GMT; Hi reflectees ! the term "one way propagation" merely describes the fact that on a given path one station can hear another and the reverse is not the case. Of course there are factors like noiselevel; /archives//html/Topband/2007-11/msg00056.html (7,036 bytes)
