341. [AMPS] ICE Filter Update (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Tue, 27 Apr 99 15:28:04 -0500; Well, I think so too. Although, ICE admitted to my dealer that they have had some recent problems. I think what the real problem is is that the series caps in the filter are silver micas. These I be; /archives//html/Amps/1999-04/msg00404.html (7,484 bytes)
342. [AMPS] Power Meter Readings Question (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Tue, 27 Apr 1999 23:05:23 -0500; Hi all, Got a question for you about power meter readings. I have a Daiwa NS-660PA cross hair power meter. I have taken everyone's advice and eliminated my antenna tuner for the time being. I am just; /archives//html/Amps/1999-04/msg00405.html (8,789 bytes)
343. [AMPS] Power Meter Readings Question (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Wed, 28 Apr 99 09:48:50 -0500; Yep. That's what I've seen! It looks decent on 40M but reactive elsewhere. VSWR is about 2.5 or 3:1 which isn't too bad...... So I've learned. I've heard lots of people say that it's an all band ant; /archives//html/Amps/1999-04/msg00410.html (10,284 bytes)
344.

345. [AMPS] Bandpass filters - where to put them? (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Wed, 28 Apr 99 13:44:08 -0500; The guy at ICE suggested putting the filter between the transceiver and the brick. He said that it would still filter the spurious output of the radio and provide a clean signal to the amplifier. Whi; /archives//html/Amps/1999-04/msg00416.html (8,955 bytes)
346. [AMPS] Band Pass Filtering (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Wed, 28 Apr 99 17:00:44 -0500; I must say that ICE's customer service has been good. The point is that I do believe a filter should go AFTER an amplifier. But I've been wrong on other things and I could be wrong on this too. I am; /archives//html/Amps/1999-04/msg00420.html (8,940 bytes)
347. [AMPS] Bandpass Filtering (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Wed, 28 Apr 1999 21:36:17 -0500; Well, any amplifier except a PERFECTLY linear amplifier (which doesn't exist) will produce harmonics and intermod. A class B device will produce more than a class AB device which will produce more t; /archives//html/Amps/1999-04/msg00430.html (8,192 bytes)

I am still trying to figure out what their duty cycle really is. Good. Sounds like you have a working unit. One of my 2M filters does work and work at 150 W.

349. [AMPS] Band Pass Filtering (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Wed, 28 Apr 1999 21:41:04 -0500; Huh? In all my years in both amateur radio and engineering commercial products I have always seen filters AFTER the final amplifier, not after the exciter. Are you saying that's incorrect? 73, Jon K; /archives//html/Amps/1999-04/msg00432.html (8,723 bytes)
350. [AMPS] Band Pass Filtering (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Wed, 28 Apr 1999 23:42:04 -0500; Hi Dave, Thanks for the note. With regards to ICE's HF filters, Mike Koss there told me today that older designs of their HF filters would fail at less than 200 Watts. They have done some redesigns; /archives//html/Amps/1999-04/msg00434.html (9,603 bytes)
351. [AMPS] Band Pass Filtering (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Thu, 29 Apr 99 09:49:59 -0500; Why can't the bandpass filter knock out the amps harmonics? Surely it does some benefit. These ICE units are kind of interesting. They use impedance transformation techniques. Basically, they consis; /archives//html/Amps/1999-04/msg00446.html (9,003 bytes)

[AMPS] Care and feeding of your Eimac 3-500 (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Tue, 2 Mar 1999 19:17:04 -0600; Actually, we are looking for "Care and Feeding of Power Grid Tubes." Perhaps it's very similar to yours, but probably more generic. That would be great if I had 3-500's. Everyone talks about this "my; /archives//html/Amps/1999-03/msg00032.html (8,681 bytes)

(score: 1): Author: jono@enteract.com (Jon Ogden); Date: Thu, 4 Mar 1999 22:41:38 -0600; Phil, I think John said the opposite (at least how I read it). That is, the 105C caps have less performance than the 85C caps. That would only make sense. Something always has to give when you impro; /archives//html/Amps/1999-03/msg00096.html (9,422 bytes)
355. [AMPS] Ripple current ratings of high voltage caps. (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Fri, 5 Mar 99 16:05:28 -0600; Hmm? Not necessarily.
