1. [AMPS] Metering a GG amp (score: 1): Author: kb7ww@chatusa.com (Arthur Moe); Date: Mon, 01 Feb 1999 10:37:48 -0800; I have some very vice 1ma meters that I would like to use in my amp project. Question is, which method to use, wind shunts or use them as volt meters and measure the voltage drop across a 1 ohm resis; /archives//html/Amps/1999-02/msg00030.html (7,356 bytes)
2. [AMPS] Metering a GG amp (score: 1): Author: G3SEK@ifwtech.demon.co.uk (Ian White, G3SEK); Date: Mon, 1 Feb 1999 20:14:22 +0000; Shunts are better when everything is working normally, because they produce the minimum voltage drop, -BUT- in the event of current surge (due to an arc or whatever) it's more difficult to protect sh; /archives//html/Amps/1999-02/msg00039.html (8,939 bytes)
3. [AMPS] Metering a GG amp (score: 1): Author: measures@vc.net (Rich Measures); Date: Mon, 1 Feb 1999 15:46:22 -0800; Simple shunts also have the disadvantage of one's not being easily able to calibrate the meter. I like to start with an easy to obtain standard value such as 0.1 ohms for the shunt, and then calibra; /archives//html/Amps/1999-02/msg00041.html (8,158 bytes)

5. [AMPS] Metering a GG amp (score: 1): Author: Peter_Chadwick@mitel.com (Peter Chadwick); Date: Tue, 2 Feb 1999 10:18:26 -0000; No disagreement with Ian or Rich on this: just a warning. Stick to old fashioned moving coil meters rather than fancy digital ones, cheaper though they may be. I've had enormous grief from digital vo; /archives//html/Amps/1999-02/msg00054.html (7,635 bytes)
6. [AMPS] Metering a GG amp (score: 1): Author: wlfuqu00@pop.uky.edu (William L. Fuqua III); Date: Tue, 2 Feb 1999 08:18:45 -0500 (EST); A friend of mine had built an amplifier and his plate current meter would read very little current when the transmitter was keyed. In fact the current would decrease some times. He showed me the sche; /archives//html/Amps/1999-02/msg00055.html (7,914 bytes)
7. [AMPS] Metering a GG amp (score: 1): Author: km1h@juno.com (km1h@juno.com); Date: Tue, 2 Feb 1999 11:50:34 -0500; Home made shunts work fine if you have the ability to accurately calibrate. Fine copper wire shunts also are not very temperature stable and suitable resistance wire is not a common item in small qty; /archives//html/Amps/1999-02/msg00073.html (8,764 bytes)
