Hey, folks...
Why go off list? I am soon to install engine and would like to see
representative photos.

Apply a ground to this pin to have the encoder output on all the time. This
is required to be on all the time with every modern transponder.

I have been using xPanel and I like it. In my opinion it is much better
than the online versions since you can easily add instruments that it
does not have in the data base. Also you get side and top views. It is
a good product for laying out panel design concepts. However, there is
no measuring tool or easy way to move instruments into an exact
location. You would need to use some other tool to actually cut the panel.
They do have a free web based product.
You can try XPanel 5000 in trial mode to see if you like it.
XPanel software is here <http://www.xpanelsoftware.com/Index.htm>

I spoke to Superior at the RENO air races this weekend and was surprised to
find that they reduced their price several thousand dollars AND have a
special this month of $500 off and free shipping if delivered before
12-31-06. I Originally planned on a TMX but I will have to look at all the
options now.

For the encoder I plan on using a seperate fuse to the POWER IN pin (8) supplied
from the a/c power to reduce warm up time and then use pin (14) SWITCHED POWER
IN as indicated by the schematic for the switched power back to the transponder.
Now for the question. The transponder schematic shows two pins together
(8,20) used for SWITCHED POWER OUT. Do both of these get wired to the switched
pin number 14 or bacause I'm powering the encoder pin 8 with its own power is
one of these pins left empty?

The transponder schematic shows a suppression OUT pin 1and a EXT. DME suppression
IN pin 6. Because I do not have a DME I understand that both of these pins
would be empty. Would this be what the encoder schematic is showing as the strobe
input? If so then this pin would not be used and would be pigtailed to the
fround pin.

Dennis,
What Transponder and what encoder are you using? Supression I/O is only used
for other L band devices like active traffic (tcas) and DME.... They all
work around 1030-1090 MHZ and the suppression lines are only used so only
one device is active for a split second.
Strobe input at the encoder should be tied to ground, I run my gray code
wires A1, A2, A4, B1...etc and power and ground to the encoder. some
transponders supply switched power out to simplify the wiring to the
encoder. If your transponder has switched power out, thats what I would use
to power the encoder. It does not need its own circuit breaker in general.
I would supply ground to the endcoder by splitting the ground to the
transponder (at the transponder rack) and sending one leg to the encoder.
Then I would take that ground and split it into two at the encoder, one
hooked to the ground pin and the other hooked to the strobe pin. Like I
said before, most all transponders want to see the Gray Code (altitude)
input at all times, and the strobe pin being tied to ground means that the
encoder will always be sending out gray code info.
If Im too confusing or you need more info just let me know.

Dennis,
If you are powering your encoder right from a fuse from the bus (to reduce
warm up time) the switched power pin out of the transponder will be left
empty. 8 and 14 are tied together on multi voltage encoders.... the old
convention was 28 volts on pin 8 and 14 on pin 14....
Run your fused encoder power to pin 14 and leave pin 8 empty, run no other
power wires from the transponder swithced power.
I just read this message after i sent the previous. I still want to know
exactly shich encoder and transponder you are using. I could draw you up a
schematic and fax it to you.
Let me know.
Charlie

Several years ago Gary Hansen had a crack propagate along the inboard top
wing skin along his rear spar. By the time he discovered the problem it had
propagated along several aft spar to skin rivets (paint hid some of the
problem for a while). Only solution was to remove the wing and replace the
entire inboard skin. This is not an easy or fun job on the RV-6A as the wing
cannot be removed without removing the main gear mounts, you RV-7/8/9 guys
have it sooooo easy. I think the problem is more common than we hear about,
guys who have cracks in benign areas just stop drill them and don't give it
a second thought! Unfortunately Gary and his RV are no longer with us so I
can't ask him what he believed caused the problem.

...........This is the first report I can recall of a crack in any of the
wing skins. I think there was something unique about this situation....
