Re: [TowerTalk] Slow Attenuation of Incoming Signal (score: 1): Author: "Jim Brown" <jim@audiosystemsgroup.com>; Date: Thu, 19 Oct 2006 11:44:16 -0700; On at least two occasions, I've traced that symptom to a T-R relay in an amplifier that died soon afterwards. It could be a relay in a transceiver, and even a bad coax connector. Jim K9YC ___________; /archives//html/Towertalk/2006-10/msg00530.html (7,198 bytes)
3. [TowerTalk] Slow Attenuation of Incoming Signal (score: 1): Author: <john@kk9a.com>; Date: Thu, 19 Oct 2006 15:37:58 -0400; If it's only on 40m, it is probably a bad antenna relay. If it is on all bands it's probably an amplifier relay. I have experienced both problems and I now never mount an antenna relay up on the towe; /archives//html/Towertalk/2006-10/msg00535.html (7,893 bytes)

Is the 40 an ungrounded dipole? If the answers to both of these are yes then the choke from the center connector on the chassis connection to ground may be open; /archives//html/Towertalk/2006-10/msg00563.html (9,796 bytes)
