1. [TenTec] Strange FD RFI (score: 1): Author: Kim Elmore <cw_de_n5op@sbcglobal.net>; Date: Mon, 25 Jun 2012 20:26:58 -0500; I'll pop this out here to see if anyone has any good explanations for what I experienced. As I said in a prior post, I proudly produced my freshly aligned, roofing-filter equipped, vintage (high seri; /archives//html/TenTec/2012-06/msg00115.html (10,572 bytes)

It's not pretty - the switching PS in them puts a lot of garbage back; /archives//html/TenTec/2012-06/msg00119.html (8,512 bytes)

Generators don't like rapid load changes such as trying to follow the waveform of a SSB signa; /archives//html/TenTec/2012-06/msg00121.html (10,048 bytes)

We used a standard, old-fashioned rotary AC alternator, probably 8-10 kW or so. It's not a DC-AC inverter type, so I expect that it mak; /archives//html/TenTec/2012-06/msg00122.html (9,511 bytes)

As far as I know, this is a standard rotary AC alternator so doesn't do any inverting to get to the AC. As such, I expect (but didn't verify) it makes a more-or-less sine wave-ish; /archives//html/TenTec/2012-06/msg00124.html (13,536 bytes)

That might help determine if the issue came from the RF or t; /archives//html/TenTec/2012-06/msg00127.html (9,054 bytes)

I briefly thought about doing something like that, but (horrors!) there were no dummy loads to be had on site and I didn't want to go back home (again) to grab mine.

Re: [TenTec] Strange FD RFI (score: 1): Author: "Frederick Mott" <fredmott@zoominternet.net>; Date: Tue, 26 Jun 2012 09:30:10 -0400; I think that a good line filter such as the Corcom EMI F3482 / F3482X just might be the solution. The filter that I mention is rated at 55 amps @ 110 VAC & at 40 amps @ 250 VAC. Something else that m; /archives//html/TenTec/2012-06/msg00131.html (8,664 bytes)
