[TenTec] WAS: Omni 6 Logic board failure

[Ron Notarius W3WN]

Hi Neal,

Well, as a "new" (to me) owner of an Omni VI since last fall, of course this is of more than academic interest to me.  I like this rig!  I'd hate to see it become nothing more than a paperweight and a display item in the shack.

Also, we need to keep in mind that this is not just an academic discussion for the Omni VI, but will happen with more and more radios of that era going forward as time goes by.  And not just those by Ten-Tec.

I guess the first specific question I'd have in mind (and I don't know who at Ten-Tec could answer this) is whether or not the original bare circuit board either is available or if a few more could be run off?  If that's possible,  then the next obvious question is what part(s) are now made of Unobtanium & what would be involved in replacing them?

That would strike me as the most cost-effective way of coming up with a direct "plug-in" replacement.  And it MAY be a case that IF someone was willing to build a quantity of the boards on behalf of Ten-Tec, a deal could be worked out to do just that... or if not on behalf of Ten-Tec (as that may not be practical for any of an unknown number of reasons), on behalf of those willing to service their radios themselves.

However:  If the original board is no longer available and can not be recreated, we are dealing with a complete re-engineering effort.  At what point does it become worth it regardless of the cost?

This all being said, we are now getting into a realm beyond my own level of knowledge, and I don't want to make a presumption on what can or can't be done when I don't know what I'm talking about.  (I know, famous last words).  

But at least Ten-Tec's service people were willing to talk to you.  I know quite a few owners of, ah, radios of other (off-shore) manufacturers who have questions of a similar nature, and simply get told "sorry, can't be fixed" and nothing more.

Hi Ron,

I'm happy that other people are thinking about this! It's complicated.

Whew! That's quite a task, and as you alluded to, but I don't imagine
the company would be interested in helping - and they might have
intellectual property issues with some of this, too. It's one thing to
do a run of custom chips if there was a SPECIFIC part that was
failing, but to re-engineer a board ... The other idea would be to use
a "daughter-board" scenario where an add-on board with replacement
circuitry would plug into an IC socket. 

But this is all academic unless we can zero in on a specific part of
the board, and apparently we are not going to get that from the
company. Someone has to troubleshoot to the component level, be willing
to pay for it, and then share the information. Or a user group takes a
collection and pays for a radio to be fixed. How much are you going to
donate to the cause? It could easily be in the $500 range. 10 people X
$50 = Hmmm.
