21. [AMPS] ACOM Amps (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Mon, 02 Jul 2001 07:08:25 -0500; They are alive and very well. They had a very nice booth at Dayton this year. One of my friends, Tom, AE9B, went and spent some time looking at the amps and talking to the guys. He was very impressed; /archives//html/Amps/2001-07/msg00013.html (8,604 bytes)
22. [AMPS] tvi. (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Mon, 02 Jul 2001 07:16:06 -0500; I agree with Phil's comments about the electrical stuff. Also, tell him to call up Amidon and order their FT-240-77 torroids (I believe the 240 is the largest if I remember correctly). Get a torroid; /archives//html/Amps/2001-07/msg00014.html (11,639 bytes)
23. [AMPS] ACOM Amps (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Tue, 03 Jul 2001 07:49:12 -0500; Running high power with high SWR on coaxial transmission line is not bad engineering practice provided the voltage peaks do not exceed the rating of the dielectric. If everything is kept within the s; /archives//html/Amps/2001-07/msg00035.html (8,631 bytes)
24. [AMPS] Making tubes (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Fri, 06 Jul 2001 07:17:00 -0500; Yeah, but go back through history and look at the first tubes! They sure weren't the equivalent of what we see on the market today. Sure, homebrewing of a tube could be done, but I would bet that it; /archives//html/Amps/2001-07/msg00077.html (8,210 bytes)
25. [AMPS] Input circuit (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Fri, 06 Jul 2001 07:39:26 -0500; Hi Peter, I think most people sort of use a "dead bug" type configuration for their input circuits. At least that's what I used. It was easier that way to group all the proper values around my input; /archives//html/Amps/2001-07/msg00078.html (8,739 bytes)
26. [AMPS] tuned inputs (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Tue, 10 Jul 2001 06:38:30 -0500; I forgot to mention this back when I posted my reply on this topic. It's a most excellent suggestion and works well. One more suggestion is that you leave the tube in the socket and tie the resistor; /archives//html/Amps/2001-07/msg00132.html (7,682 bytes)
27. [AMPS] Setting the record straight--Dick Ehrhorn (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Sat, 21 Jul 2001 10:34:01 -0500; I gotta throw my 2 cents in on this one because this statement is just not completely accurate. Building a stable amplifier that has high gain becomes increasingly difficult the higher ones goes in f; /archives//html/Amps/2001-07/msg00251.html (10,538 bytes)
28. [AMPS] Emails with the big V (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Sat, 21 Jul 2001 23:33:34 -0500; This V is very bad. I get a V update from a service at work. We were alerted to this last week. This one is very destructive. Skips advice to not open unknown attachments is very useful and good comm; /archives//html/Amps/2001-07/msg00264.html (7,173 bytes)
29. [AMPS] about one of the latest v's (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Sun, 29 Jul 2001 07:50:38 -0500; So in some ways this V is easy to detect as you'll get attachments from a lot of people you do NOT know. 73, Jon NA9D -- Jon Ogden NA9D (ex: KE9NA) Member: ARRL, AMSAT, DXCC, NRA http://www.qsl.net/k; /archives//html/Amps/2001-07/msg00350.html (8,287 bytes)

It it's an EXE or a PIF or an SCR when you are expecting DOC, XLS, PDF, etc. then you know you have a problem. 73, Jon NA9D -- Jon Ogden NA9D (ex: KE9NA); /archives//html/Amps/2001-07/msg00351.html (8,289 bytes)
31. [AMPS] Chip Capacitors for Filament ,Grid, or Screen Bypass? (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Wed, 06 Jun 2001 22:59:02 -0500; A couple of companies have high voltage HF chip caps that would work great. Voltage ratings are into the kilowatt range. They are design for these sorts of applications. One specifically is the MRI i; /archives//html/Amps/2001-06/msg00059.html (8,491 bytes)
32. [AMPS] 4cx250* amp building plans (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Thu, 07 Jun 2001 07:04:44 -0500; You're right, Rich. I think the temptation is to look at it and since it's not DC grounded, we don't (at least I don't) always see the AC ground right away. The term "grounded grid" while accurate ca; /archives//html/Amps/2001-06/msg00063.html (9,250 bytes)
33. [AMPS] Review of Antenna Tuner from Dayton (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Tue, 19 Jun 2001 07:33:47 -0500; Hi all, Well, it might not be specifically amplifier related, but I thought I'd let you guys now a little about the new antenna tuner I picked up at Dayton. Yeah, yeah, I know - some of you don't lik; /archives//html/Amps/2001-06/msg00152.html (11,807 bytes)
34. [AMPS] Review of Antenna Tuner from Dayton (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Tue, 19 Jun 2001 21:47:41 -0500; Good point. This sucker is well built. The caps are very large. Again, I've not seen a better built unit. Of course, the Nye Viking unit may be bigger and better, but it costs nearly $1000 too. 73, J; /archives//html/Amps/2001-06/msg00176.html (9,015 bytes)
35. [AMPS] Review of Palstar Antenna Tuner from Dayton (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Tue, 19 Jun 2001 22:04:19 -0500; I think Paul is correct. The inductor in my tuner is NOT the one shown in the AT4K picture. I believe they did do some changes. I believe the quality of the inductor is good. I looked it over pretty; /archives//html/Amps/2001-06/msg00177.html (8,613 bytes)

[AMPS] Review of Antenna Tuner from Dayton (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Wed, 20 Jun 2001 17:52:47 -0500; Well, my problem was that my capacitance on my old tuner was pretty much maxed out. I couldn't add more. Believe me, I remember our conversation. But when the cap is fully meshed when it arcs, there'; /archives//html/Amps/2001-06/msg00202.html (10,401 bytes)

[AMPS] Review of Antenna Tuner from Dayton (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Thu, 21 Jun 2001 09:37:45 -0500; That is a sticky widget with some of the possible configurations of the T-match. However, if one has a good low pass filter installed after one's amplifier (for above HF harmonics) and one has suffic; /archives//html/Amps/2001-06/msg00232.html (8,853 bytes)

It's a half way decent size. Unless your amplifier pulls some excessive current, I don't see why not. They relay was put into the FT-1000D f; /archives//html/Amps/2001-06/msg00248.html (8,635 bytes)
40. [AMPS] re: Board Decorum (score: 1): Author: na9d@speakeasy.net (Jon Ogden); Date: Fri, 22 Jun 2001 07:01:21 -0500; Yeah, we've had some pretty good non-amplifier discussions here over the years. There was one that went on forever about a specific English car a couple years ago. There's been some other good ones t; /archives//html/Amps/2001-06/msg00249.html (8,026 bytes)
