1. [TowerTalk] Using a dip meter (score: 1): Author: "Scott McClements" <kc2pih@gmail.com>; Date: Thu, 20 Mar 2008 16:10:01 -0400; Hi, Being a new ham, I have never used a grid dip meter or actually seen someone use one. I've read the historical movement from people using grid dip meters to "SWR analyzers". I've also read that u; /archives//html/Towertalk/2008-03/msg00378.html (7,621 bytes)
2. Re: [TowerTalk] Using a dip meter (score: 1): Author: Jim Lux <jimlux@earthlink.net>; Date: Thu, 20 Mar 2008 15:43:40 -0700; Depends on what you're doing. For instance, a slotted line is a fine way to illustrate SWR in an educational setting, but I'd hate to have to use one instead of a VNA. The grid dip basically has an o; /archives//html/Towertalk/2008-03/msg00379.html (9,455 bytes)

Re: [TowerTalk] Using a dip meter (score: 1): Author: "Jeff Carter" <towertalk@hidden-valley.com>; Date: Thu, 20 Mar 2008 19:05:21 -0400; I've been following this thread with interest, largely because I'm ignorant about the utility of these meters. Jim, your description fits with what I had concluded about them, that being if you had p; /archives//html/Towertalk/2008-03/msg00380.html (11,997 bytes)

Re: [TowerTalk] Using a dip meter (score: 1): Author: Chris Wendling <cpwendling@yahoo.com>; Date: Thu, 20 Mar 2008 17:45:46 -0700 (PDT); Jeff, The dip meter is a very versatile instrument, with very many uses. I own several makes, and use them regularly. Some of the applications are: 1) Receiver adjustments 2) Transmitter adjustments; /archives//html/Towertalk/2008-03/msg00383.html (8,290 bytes)

Re: [TowerTalk] Using a dip meter (score: 1): Author: "Jeff Carter" <towertalk@hidden-valley.com>; Date: Thu, 20 Mar 2008 21:50:01 -0400; Jim, My network analyzer will let you choose Z0 (characteristic or system impedance), but I never move it off 50 ohms because I'm almost always working with 50 ohm systems.

I can look at that and determine if there's something a dip meter will do that I couldn't figure out how to do with more recent technology.

It should work fb. The quad loop must be continuous, with no insulators. The small loop that you formed must not be shorted upon itse; /archives//html/Towertalk/2008-03/msg00386.html (10,626 bytes)

You point out something here - this was my 75 meter loop - which is not parasitic. Its driven, so its broken at the feedpoint with an center insulator.

Remove the feedline and put a temporary jumper across the insulator, and you will read the resonant frequency of the loop. You could build your little coupling loop into this; /archives//html/Towertalk/2008-03/msg00388.html (9,523 bytes)
