I have seen this problem come up quite often, not only with TT equipment, but with a variety of things. The one USB to serial converter that has worked every time for me, including with my Orion II,
Interesting that there is a new part instead of the older Siward unit. Siward no longer lists the device, so TT must have gone somewhere else. It would be interesting to see the warm-up drift plot of
Doug: Looking at the schematic of the A0 board where the switching and QSK blocking is done, I can't see that there is any special protection. All inputs have a gas tube and parallel RF choke to disc
There are lots of 'interface boxes' on the market that can send audio between your computer and radio, although in my experience, they're not really needed. The Orion II has audio inputs and outputs

That's probably the easiest one to replace with a doorknob cap. I haven't had problems with that one yet, but maybe next time I'm looking for a project, I'll replace it with a 'Ruskie' unit. Ron N6IE
http://n6ie.com/Ten_Tec_238.html Ron N6IE www.N6IE.com Instead of doing the tuner cap mod with doorknobs why not simply use higher v. disk ceramics? Mouser has 8 KV 470 pF for around 50 cents each. Y
If you do a search on e-bay for "capacitor doorknob" and you'll be surprised at the values you find. I'm looking at one right now with 5 of the same capacitors I used for $24.50 "Buy it now" price. H
I would be very interested in participating, and yes, I believe the "original" Orion used the same oscillator. While the mod on my website mitigates the problem considerably, it can't really cure it.
If there is a problem in the radio, it would most likely be on the A0 board, but would be hard to diagnose. It could simply be that the radio is at a 'hot spot' on the beverage transmission line. A q
I avoided getting into the recent food-fight on this reflector about problems with the Orion and Orion II firmware since the volley seemed more emotional than objective. Those of you who know me or h
It's probably worth sending a copy to Jack Burchfield...maybe I'll do that! Ron N6IE www.N6IE.com Thank you for keeping the list, Ron. But I don't think just publishing it to the web or talking about

I just wrote an e-mail to Jack last night summarizing the problems. Ron N6IE www.N6IE.com Have all these known issues been reported to TT? Maybe someone should send it to Jack B. At TT? 73, Lee, KC9C
Rick--a lot of those problems are common to both the O1 and O2, but I'm sure there are problems that only effect one or the other. If you go over the list I posted here a few days ago, or check the o
What you see is normal for 2.041XT which is a beta firmware load. You'll also notice that when you tune, the S-meter stays exactly where it was when you started tuning until you stop, so if you're li
It's the hardware adjustment for the mic input level. Ron N6IE www.N6IE.com There's an access hole on the bottom of the Orion about 1 inch (2.5 cm) behind the USER2 button. It provides access to a tr
This is a well-documented problem in the Orion II that has to do with a different attenuator/chip scheme between the speaker circuit and headphone circuit. It's not impedance related, although large
Hank: It would interesting to see the difference in output levels to the phones with the new firmware. It's definitely louder, but I haven't measured how much. Ron N6IE www.N6IE.com The headphone out
