82. [TenTec] Orion at QRP levels (score: 1): Author: Ralph Matheny <mathenyr@marietta.edu>; Date: Tue, 3 Feb 2009 21:06:33 -0500 (EST); This past weekend I wanted to make a few Q's in the QRP SSB contest, so I cranked down the Orion to 5 Watts and called away. In a few minutes, I received what I believe was an accurate report that th; /archives//html/TenTec/2009-02/msg00077.html (7,318 bytes)
83. [TenTec] Orion display (score: 1): Author: Ralph Matheny <mathenyr@marietta.edu>; Date: Wed, 18 Feb 2009 11:19:22 -0500 (EST); I wonder if anybody has successfully changed the display in an Orion in the field. My display is getting pretty bad (lines, dark places) and I am going to nhave to give in and make a fix. I hate to s; /archives//html/TenTec/2009-02/msg00267.html (6,805 bytes)

Re: [TenTec] Orion display (score: 1): Author: Ralph Matheny <mathenyr@marietta.edu>; Date: Wed, 18 Feb 2009 16:34:27 -0500 (EST); Thanks, guys.....the caps have been replaced after a failure a few months back. I'm pretty sure the problem has to be with the display itself. I just got word from TT that the display is available at; /archives//html/TenTec/2009-02/msg00276.html (8,903 bytes)
85. [TenTec] BC Freq selections (score: 1): Author: Ralph Matheny <mathenyr@marietta.edu>; Date: Mon, 27 Apr 2009 12:11:13 -0400 (EDT); You can select BC freqs on either VFO, IF the VFO is not assigned to the transmitter. This is true on the ver of firmware I have (1.372, I think) but may be different on other versions. So--to answer; /archives//html/TenTec/2009-04/msg00344.html (7,598 bytes)

Trouble-shooting wise, any of the electrolytic caps on the board that has the AF amp chip would be good suspects. Those sometimes fail when un; /archives//html/TenTec/2009-09/msg00282.html (7,458 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 (7,906 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/msg00130.html (8,536 bytes)

[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 (8,327 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 (7,662 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/msg00246.html (7,346 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.

(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 (8,475 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/msg00252.html (8,515 bytes)
