1. [Amps] tank calculations - MFJ analizer - resistor (score: 1): Author: "chuck" <ka1mwp@comcast.net>; Date: Tue, 21 Apr 2009 10:04:43 -0400; ok, quick question...(it'll be a poll) DO I leave the tube connected to the tank circuit and put on a 1/2w resistor or disconnect the tube from the tank to do the sweeps for tuning calculations some; /archives//html/Amps/2009-04/msg00177.html (6,975 bytes)
2. Re: [Amps] tank calculations - MFJ analizer - resistor (score: 1): Author: "Gary Schafer" <garyschafer@comcast.net>; Date: Tue, 21 Apr 2009 11:18:29 -0400; Yes leave the tube in! You want the capacitance of the tube in the circuit as well as all the other components that are normally in the circuit. Just put the resistor from plate to ground in a short; /archives//html/Amps/2009-04/msg00178.html (8,510 bytes)

Otherwise the output capacity, which becomes part of the tune c, isn't there. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___________________; /archives//html/Amps/2009-04/msg00179.html (7,954 bytes)

Re: [Amps] tank calculations - MFJ analizer - resistor (score: 1): Author: "Bill, W6WRT" <dezrat1242@yahoo.com>; Date: Tue, 21 Apr 2009 09:21:43 -0700; ORIGINAL MESSAGE: REPLY: Definitely leave the tube in - it is part of the tune capacitance, in parallel with the "real" tune capacitor. Here's how I do it: 1. Using the ARRL handbook or a spreadsheet; /archives//html/Amps/2009-04/msg00181.html (8,970 bytes)
