1. [TenTec] FS: Ten-Tec Orion 565 AT (score: 1): Author: Martin Ewing <martin@aa6e.net>; Date: Sat, 05 Jul 2014 18:57:29 -0400; The penultimate rig from Ten-Tec -- Put an Orion on your desk! It works fine, but it is surplus to my needs as I am rebuilding my station. I'd say the value proposition is there, even with TT's "summ; /archives//html/TenTec/2014-07/msg00112.html (7,945 bytes)
2. Re: [TenTec] New Orion Firmware (score: 1): Author: Martin Ewing <martin@aa6e.net>; Date: Sat, 4 Dec 2004 06:57:39 -0800 (PST); I think we have a problem with Orion's signal processing. Not that it can't do wonderful things and run circles around older rigs. The problem is that the signal processing is not properly documented; /archives//html/TenTec/2004-12/msg00159.html (8,742 bytes)
3. Re: [TenTec] My new Orion and a question... (score: 1): Author: Martin Ewing <martin@aa6e.net>; Date: Mon, 1 Nov 2004 05:31:25 -0800 (PST); Hi, Eric, Yes, the knob puzzle. You have to pull off the silver plastic sleeve, which you can do carefully with a knife blade or small screwdriver. Then there is a set-screw to loosen the main knob.; /archives//html/TenTec/2004-11/msg00008.html (8,875 bytes)
4. Re: [TenTec] B&W low pass filter rating (score: 1): Author: Martin Ewing <martin@aa6e.net>; Date: Mon, 1 Nov 2004 17:50:58 -0800 (PST); For what it's worth (OT), I expect the power ratings (and frequency response, too) are based on 1:1 VSWR / 50 ohms. It would be useful to know what they can do with say 2:1 VSWR. I.e., you want some; /archives//html/TenTec/2004-11/msg00039.html (8,159 bytes)

6. RE: [TenTec] TXCO unit [OT] (score: 1): Author: Martin Ewing <martin@aa6e.net>; Date: Thu, 4 Nov 2004 07:39:32 -0800 (PST); John, In a way, it's simple. That's what a frequency synthesizer does. You take a 10 MHz reference, divide it down and/or multiply it up by various ratios, mix and filter, etc. Doing it well and chea; /archives//html/TenTec/2004-11/msg00115.html (10,041 bytes)
7. RE: [TenTec] TXCO unit [OT] (score: 1): Author: Martin Ewing <martin@aa6e.net>; Date: Fri, 5 Nov 2004 12:55:48 -0800 (PST); Cheap PLLs, yes. A lot depends on the quality of the controlled oscillator. You can use a PLL to steer a crystal oscillator (oh so gently), and get minimal phase noise. Effectively, the crystal filte; /archives//html/TenTec/2004-11/msg00131.html (10,450 bytes)

The relay is a fact of life. Mine is pretty quiet and not bothersome to me. Others report total silence, but still others have your complaint.

Re: [TenTec] Orion sub receiver (score: 1): Author: Martin Ewing <martin@aa6e.net>; Date: Fri, 03 Sep 2004 10:27:54 -0400; Yes, I've seen this behavior, and some other random artifacts in SubRx tuning that come up for no apparent reason and need a power reset to fix. (v 1.371) These must be firmware programming problems.; /archives//html/TenTec/2004-09/msg00050.html (7,991 bytes)

And the "A" and "B" VFO titles, too. Not to mention "POWER" and "ALC". Saves a couple of pennies. You have to; /archives//html/TenTec/2004-09/msg00076.html (7,520 bytes)
