1. [TowerTalk] Power line filter question (score: 1): Author: Grant Saviers <grants2@pacbell.net>; Date: Tue, 20 May 2014 08:23:30 -0700; With Field Day coming, I need to build some line filters for a multi station setup. The goal is two-fold, reduce hash from the Honda inverter-generator and reduce conducted noise from other stations.; /archives//html/Towertalk/2014-05/msg00380.html (9,059 bytes)
2. Re: [TowerTalk] Power line filter question (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Tue, 20 May 2014 18:48:18 -0700; Advice? Honda generators put out trash as a common mode signal on the green wire. It is NOT acceptable to choke the green wire, but it IS acceptable to choke all three conductors. Thus, the solution; /archives//html/Towertalk/2014-05/msg00393.html (8,689 bytes)

I made up a little pigtail extension cord, and used a type 31 ferrite. Forget the exact model, but it is about 2.5" long with about a 1" or so inner diamete; /archives//html/Towertalk/2014-05/msg00396.html (8,582 bytes)

Re: [TowerTalk] Power line filter question (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Tue, 20 May 2014 20:21:03 -0700; Yes -- that's what I'm using on power cables with permanently attached connectors. I'm using 1.4-in i.d. cores when I there's no plug attached yet. 73, Jim K9YC ______________________________________; /archives//html/Towertalk/2014-05/msg00398.html (8,593 bytes)

Re: [TowerTalk] Power line filter question (score: 1): Author: Grant Saviers <grants2@pacbell.net>; Date: Tue, 20 May 2014 22:02:07 -0700; So why are x uH's of green wire inductance ok in the three wire case and not for a single green wire (engineering pls, not UL regs)? Grant KZ1W Advice? Honda generators put out trash as a common mode; /archives//html/Towertalk/2014-05/msg00399.html (9,999 bytes)

Re: [TowerTalk] Power line filter question (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Tue, 20 May 2014 22:46:18 -0700; First, if all three conductors go through the choke, a fault on the circuit will blow a breaker faster. Second, at RF, the capacitance between conductors tends to put the conductors in parallel. 73,; /archives//html/Towertalk/2014-05/msg00400.html (8,823 bytes)
