21. [TenTec] Orion still available (score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Tue, 5 Jul 2016 18:52:51 -0400 (EDT); I still have an Orion which is surplus to my needs. If you are interested contact me off list. It's a nice radio I just don/t use it anymore and somebody should keep the electrons flowing!! de K8RYU; /archives//html/TenTec/2016-07/msg00038.html (6,673 bytes)

Re: [TenTec] Omni VI+ filter problem (score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Fri, 15 Jul 2016 12:10:31 -0400 (EDT); Don't know if anybody mentioned it or not...but on the Omni-V as I remember there was a switch or jumper to compensate for gain with the narrow filters. Also...at least on the O-V the pass band tunin; /archives//html/TenTec/2016-07/msg00130.html (7,079 bytes)
23. [TenTec] Orion for sale (score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Wed, 20 Apr 2016 13:55:23 -0400 (EDT); I have one of the last Orions sold and I don't use it much any more. It is plain vanilla, no tuner, etc. I've changed the display (now blue) and replaced the caps on the Power Dist Board a few times,; /archives//html/TenTec/2016-04/msg00123.html (6,742 bytes)

Re: [TenTec] Field day antennas (score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Tue, 14 Apr 2015 12:07:44 -0400 (EDT); In my experience the 80M antenna on the higher bands will be a dud. If you must, use a loop rather than an dipole, and feed the loop with 300 (NOT 450) line via a true balanced link-coupled tuner, li; /archives//html/TenTec/2015-04/msg00136.html (8,932 bytes)

Re: [TenTec] Field day antennas (OT) (score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Wed, 15 Apr 2015 12:35:25 -0400 (EDT); My preference for 300-ohm line over 450 is that at the tuner end of the line with line lengths that seem typical I have a more moderate load for the Matchbox to deal with. I'd prefer to avoid either; /archives//html/TenTec/2015-04/msg00152.html (10,611 bytes)

Re: [TenTec] SERVICE MANUAL OMNI 5 (score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Sat, 7 Mar 2015 15:11:03 -0500 (EST); I have the manual that came with the radio and I think that is the "service manual". However, a word of caution. Some years back I did a bunch of work on my O-V and learned that all of them are not c; /archives//html/TenTec/2015-03/msg00061.html (7,720 bytes)

Key Clicks (score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Sat, 7 Mar 2015 15:21:20 -0500 (EST); Some years back W1AW was using an Omni 6 for transmissions on 1820khz and the clicks were awful. There was a modification created for the radio which fixed the problem, but I don't know if and where; /archives//html/TenTec/2015-03/msg00062.html (9,197 bytes)

Key Clicks (score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Wed, 11 Mar 2015 13:31:37 -0400 (EDT); A "Google" of "W1AW + 160 Meter Key Clicks" brings up a posting or two regarding the click problem. It was promptly fixed, partly by eventually a freq change but mostly by mods to what I believe was; /archives//html/TenTec/2015-03/msg00088.html (8,990 bytes)

(score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Mon, 31 Dec 2012 00:40:30 -0500 (EST); I chased a similar problem in my Omni-V a few years back. It turned out to be a TR switch problem. You can test this idea by pulling the input to the Rx board, or even switching to the Rx antenna usi; /archives//html/TenTec/2012-12/msg00249.html (8,205 bytes)

It is modified for 5W per TT instructions, has the much desired Noise Blanker Card, and comes with a 10-Meter an; /archives//html/TenTec/2012-04/msg00262.html (7,496 bytes)

(score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Sun, 15 Jan 2012 23:18:48 -0500 (EST); Replaced mine about a year ago. However.....since that time when I first turn the radio on, the screen is dim and re-adjusts over a few minutes. I've not explored the problem, and I wonder if that ra; /archives//html/TenTec/2012-01/msg00069.html (8,508 bytes)

Generally like the v.9 firmware, but I have stumbled upon a "bug" (to me). When I operate "split", if I use the "tune" button it clears the radio out of split mode; /archives//html/TenTec/2010-10/msg00244.html (7,497 bytes)

[TenTec] Century 21 FS (score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Sun, 24 Oct 2010 11:00:06 -0400 (EDT); If anyone is interested in picking up a Century 21 Analog give me an email.

[TenTec] sick Orion (score: 1): Author: Ralph Matheny K8RYU <mathenyr@marietta.edu>; Date: Tue, 19 Jan 2010 23:03:29 -0500 (EST); Before I ship it off, I thought I would shoot out a message and see if this is one that can be delt with here. My Orion has no RF output, appears to draw current in transmit, heat sink gets warm and; /archives//html/TenTec/2010-01/msg00235.html (8,017 bytes)

It seems the problem was not in the Orion, but rather the TR relay in my amp, one of the Kilovac jobs. It seems that it makes contact well enough to receive OK, but; /archives//html/TenTec/2010-01/msg00248.html (7,352 bytes)

There is NO money coming in to pay for the development. I would have (and still would) pay fo; /archives//html/TenTec/2009-11/msg00131.html (8,686 bytes)

It isn't "perfect" but is "nice", I don't use it and would send it out on approval. I have no idea what it is worth these days.; /archives//html/TenTec/2009-10/msg00178.html (8,787 bytes)

Trouble-shooting wise, any of the electrolytic caps on the board that has the AF amp chip would be good suspects.
