1. [Amps] how to measure tank (score: 1): Author: Lynn Osterbur <no9z@yahoo.com>; Date: Sat, 29 Nov 2008 18:50:47 -0800 (PST); I am starting to forget all I know! Components Homebrew amp and cushman service monitor What is the proper way to measure a pi network with a tracking generator and spectrum analyzer.

Re: [Amps] how to measure tank (score: 1): Author: George Badger <gbadger@sbcglobal.net>; Date: Sat, 29 Nov 2008 21:02:21 -0800 (PST); Lynn Put a resistor from plate ground to simulate the load and look into the output with an MFJ 259. Tune for a match. Works like a charm. George W6TC I am starting to forget all I know! Component; /archives//html/Amps/2008-11/msg00251.html (7,713 bytes)

Re: [Amps] how to measure tank (score: 1): Author: DAVE WHITE <mausoptik@btinternet.com>; Date: Sun, 30 Nov 2008 12:53:24 +0000 (GMT); I'd echo W6TC's good advice - a resistor of the same value as your calculated resonant load impedance or that off the data sheet for the drive and ht you're using. Just make sure it's a non-inductiv; /archives//html/Amps/2008-11/msg00253.html (10,119 bytes)

Re: [Amps] how to measure tank (score: 1): Author: Rick Stealey <rstealey@hotmail.com>; Date: Sun, 30 Nov 2008 13:33:55 +0000; One way is to hook up like the other guys are saying, but also put a directional coupler in series with the tracking generator. Any reflected power will show up in the coupled port, where you attach; /archives//html/Amps/2008-11/msg00254.html (7,920 bytes)

I don't own a monitor, but could an MFJ-259 be used to tweak the bandswitched input tuning coils of an AL-811 by sweeping the input (while keeping the; /archives//html/Amps/2008-11/msg00255.html (9,326 bytes)

Re: [Amps] how to measure tank (score: 1): Author: Robert Groh <rgroh@swbell.net>; Date: Sun, 30 Nov 2008 07:50:34 -0800 (PST); One thing to keep in mind - the input impedance of a GG amplifier is strongly influenced by the output tuning of the amplifier and the output levels of the amplifier. Hence the suggestion that checki; /archives//html/Amps/2008-11/msg00257.html (10,105 bytes)

Hell, I wish there'd been an Amps Reflector when I built my first multiband HF amp. In fact, I wish there'd been an internet! :-) cheers Dave G0OIL One thing to keep in mind -; /archives//html/Amps/2008-11/msg00258.html (10,893 bytes)
