Good Morning gmcjetpilot,
That unit looks very interesting, but I found no data in the brochure
concerning the shape, weight and footprint of the antenna nor of the switch and
test unit that is normally mounted in the cockpit for such units. Is that not
included with the unit?
Happy Skies,

--> AeroElectric-List message posted by: Sheldon Olesen <saolesen@sirentel.net>
In wiring my audio panel I found I have 4 unswitched audio inputs but
seven devices to hook up to the inputs.
Can I run 2 wires into each input? Furthermore, if I use 2 wires per
input do I need some protection (diode?) to keep the 2 devices
electrically separated ?
Or would it be better to use the ADF, DME and AUX switched inputs?
Thanks

A rubber duck antenna on a decent ground plane is only slightly
degraded from a full sized 1/4-wave in terms of performance. I
almost got a rubber duck stuck on top of a Beechjet (under the
fiberglas dorsal fin cover) until some well meaning but uninformed
bureaucrat decided the antenna supplied with the ELT was part of
the TSO and a substitute could not be made legally without getting
the TSO ammeneded. Sooooooo, instead of a decent performing antenna
with good SWR we have a reasonable performing antenna with poor SWR
because of proximity to metalic components in the fin cap.
If it were my airplane, I'd have no problems with a rubber duck
antenna designed for hand-held, VHF comm transceivers.

Sheldon -
The tech who wired our stack said that it would be OK to double or triple
up on the inputs. He suggested that a 300 ohm resistor be put in series
with each input wire. We ended up putting 4 or 5 into the single
unswitched audio pin of the Garmin 340. However, I have read on one of
these lists that a 1000 ohm is recommended. Can't vouch for the accuracy
of that or the author's qualifications. If you use the ADF or DME input
lines, then you must placard the button or position on the selector switch
as to what signal it is controlling.
Hope this helps,
John

Check your audio grounds from the KNS-80, make sure they go to a
dedicated audio ground. Also check that you audio line out is going to
the correct place( the proper pin on you audio panel. I should mention
the audio out from the KNS-80 should be a shielded pair with the shield
ground being terminated at the audio panel ONLY.

I have a Lancair 320 with a KNS 80 Nav system installed. I did all the
wiring myself, ( probbly why I have a Problem). With all the other
avionics
on, and the KNS 80 "OFF" I have no static noise going through my
headset.
When I turn the KNS 80 "ON" I get static through my headset. Something
else
thats weird is when I turn the volume up on the KNS 80, the static gets
louder, and the audio panel is "OFF" Any Advise???

Hi to all
I am presently working on the fuse of an RV7A. Finish kit is on the way. I
know now is the time to decided on the wiring of the plane. The plane will
be all electric. Two e-Mags, electronic fuel injection, Dynon avionics /
engine monitor.............My intentions are dual alternators / batteries
/plit bus. Easier said than done. Other than my study of aeroelectric
connections and some electronics for dummies types books I am a real novice
in this area.
Your suggestions and help would be greatly appreciated. Where to place the
second battery?Is the dual system really essenstial?
Thanks in advance for your help

Thanks Mike, I know I didn't have a shielded wire on the audio out, I'll
change it and see what happens. Thanks, Guy

You don't say what your intended type of flying is to be. Keep in mind the
RV7/7A is not a really good IFR plane due to its sensitivity. I would first
decide what your desired flying requirements are and then decide if you
really need dual everything (battery,alternators) for safe flights. The
reason I mention this is because I started with this dual everything goal in
mind to start with. After looking for ways to mount the second battery and
more carefully determining why I needed it, I found that I did not for my
intended type of flying. By rotating in a new battery every year the extra
alternator may not be needed. Keep studying the manual and determine what
your flying needs are first. IMO, it is better to think about keeping it
simple as possible for your flying needs. do not archive.

That's a lot of trouble to keep a dual e-Mag system running. Why not one E
and one P-Mag and you have a lot more backup with much less complexity.
Dual Alternator's Ok and you could get by with a smaller battery for the
avionics BU. Take a look at the Z-13 diagram with dual E/P-Mags. Add a
smaller avionics battery and simplify the system. Or not,...:-)
