TE compensation and vario response times

Hello Pilots,

Seeing the question about CAI 302 tones prompts an issue I have with my 302. I have a relatively new V2C. It has a 302 and an LX 16 electronic vario for back up. I am running both off the TE probe in the fin. I had the 302 response times for both audio and pointer set relatively fast as I had done with my previous system and running 0% electronic compensation. The 302 is bonkers in any turbulence or transitions. I have tried adding some electronic compensation w/o improvement. In order to tame it I had to slow both audio and pointer response times down further than I would like.

So the questions:
1) TE off the fin probe or go with static and electronic compensation
2) Operate with TE off the probe and some added electronic compensation
3) If running off static should I run with more than 100% electronic compensation
4) Optimum response time settings
5) Is there a solution that provide a well compensated 302 that is fast AND reasonably stable

Thanks for the insights.

Bob:

That's puzzling. You should be running your 302 on the TE probe (no
electronic compensation) and it should work great with lower response
time (this is how I have mine set up), as long as you don't have it set
below ~1.5 seconds. Remember, *some* degree of dampening is necessary,
you don't want the "air truth" in real time ... in AZ that would break
the needle off.

Mine was erratic when compared to the Borgelt, even at the 2.3 second
setting. Marty Eiler at Caracole added a restrictor to the line
leading from the "T" to the 302 and it's worked well ever since, smooth
response and a good match to the B40.. I now leave the response on the
302 set to 1.5 sec..

At Marty's suggestion I did the same thing as Ray describes. It works
great.
Try a Sheuemann restrictor on the TE line.

Where does on get a Sheuemann restrictor?

I tried to get some from Sage, no reply. Called Noelle at Williams
Soaring, had them in a couple of days. Tim Mara may have them too.
