KR> Transponder

[codylee.cramer]

I recently bought a working garmin gtx 327 transponder that I planned to use in 
my kr2 but have decided on a different route. Looking to sell for 550 shipped. 
Please contact me offline for questions or pictures.?

That is not the case in the US.  The 2020 rule requires ADS-B out.  You are 
allowed to equip with either (Mode S) 1090-ES or UAT out.  Other planes with 
ADS-B in will see either, as will the FAA.  The Mode-S is received by Radar and 
the UAT is received by the ADS-B towers (they look like a little outhouse with 
a small antenna).  In a congested area like the San Diego and Los Angeles areas 
it shouldn't make any difference as the FAA has lots of ADS-B towers.  However, 
in remote areas, it does make a difference.

Flying internationally (like crossing into Mexico or flying into Canada), or 
flying at or above 18,000', you will be required to have 1090ES.

On our trip last weekend, I was flying my KR and broadcasting UAT out.  My 
buddy flew the exact same route at the exact same altitude in an RV-7A using a 
Dynon feeding a headless Trig TT22 Mode S transponder.  We flew direct from 
KRYN (Tucson) to KLAM (Los Alamos [near Santa Fe]).  The report for his Mode-S 
transponder showed the complete flight from Tucson to Santa Fe.  My report only 
showed the last hour of the flight.  We were flying over a very remote and 
desolate area for most of the flight.  But what the reports showed is that they 
saw him on radar for the whole trip.  My ADS-B out (and In) was out of range 
from an ADS-B tower for over half of the trip.  Of course I was also able to 
see the RV-7's 1090ES transmissions and was tracking him on my GPS.

Yes Jeff- good feedback but I am still working on that comment that mode S is 
only required above 18000' , most folks around here (within 30 miles of a major 
airport) seem to think that we will need it at all altitudes.

Bill,

Since the others on here have cleverly suggested used mode C transponders 
rather than answering your question, I'll give this a shot.

If you're looking for a Mode S transponder that will be compatible with the 
ADS-B out equipment, I would suggest buying a Trig, either a TT22 or TT31 
depending on panel space available.  The TT21 will also do 1090-ES, but the 
broadcast power doesn't meet the 2020 standard.  The Trig TT22 without a face 
is also the transponder of choice used in conjunction with the Dynon Skyview 
Avionics suite.

Of course your other option would be to go with a compact Mode C transponder 
and a UAT ADS-B out unit like the NavWorX unit.  If you are starting with a 
clean slate for an installation, it will be less expensive to equip with mode-S 
(1090-ES) than to buy a mode C transponder, then add a compliant UAT 
transmitter.

We did some ADS-B performance testing last weekend while traveling from Tucson 
to Los Alamos.  The FAA now has an email address you can email some basic data 
and they will check your last flight with ADS-B out and email you a report on 
the performance of your ADS-B unit.  We tested my Skyguard TWX and a Dynon 
Skyview with a Trig TT22 mode S transponder.

The Skyguard unit meets the performance standard, but fails to meet the ADS-B 
rule because it doesn't have pressure altitude as part of it's broadcast.  That 
is a problem come 2020 as their current units don't have any methodology for 
adding pressure altitude.  

The Dynon Skyview unit with the Mode-S Trig transponder meets the ADS-B rule, 
but failed to meet the performance standard due to the inaccuracy of the Dynon 
GPS unit.  That can be easily corrected with a new GPS puck, which Dynon will 
undoubtedly be offering. 

For today, if one was planning to use a mode-C transponder and a UAT out (which 
I wouldn't recommend for a new installation), I would use the NavWorx unit.  It 
is listed at $799, but you'll find once you get done equipping it to actually 
work, you'll have roughly $1600 invested.  The NavWorx unit can be used with an 
inductive pickup that goes around your transponder coax cable to pick up your 
pressure altitude and squawk code for retransmit in the UAT Out signal if you 
don't want to have to run a gray code cable to the unit.

Wow, I'm looking at putting $8,000 of Dynon stuff in my panel and engine

I'd suggest you search the used market and salvage yards for a

No external antenna to collect gunk.  KISS (Keep It Simple Stupid)

FWIW, I don't see planning ahead and mounting antennae internally so they don't

FWIW, at best count, I think I have approximately 10 antenna that either 
transmit or receive signals external to the aircraft.  All are mounted within 
the confines of the aircraft making them all zero drag.  There is no reason to 
mount an antenna externally on a KR other than for convenience as an after

I sure hope you weren't taking the acronym as an insult. None intended. I'm not

Mark,?
One of the things from that CD on making your on antenna you let me use is that 
the transmission of that transponder antnna is in the microwave band. ?You 
should have some type of grounded barrier between the antenna and your 
important parts of you body. ?You don't have this issue with metal skin

Another reason I did this was because I was told by a very sharp EE/avionics
guy that oil and crud accumulating on the outside of my fairing (when it was
mounted outside) would change the impedance of the antenna, reducing its
efficiency and even presenting a chance of damaging the transponder due to
mismatch.  The reason I am sensitive to this is because we were discussing

I can't imagine 3/32 plywood having much effect on RF at that frequency, 
which is why I put mine inside.  Proximity to cables and other steel is 
apparently not a problem at all for any of the antennas, and I have the 
radio, transponder, ELT (which admittedly isn't doing anything MOST of the 
time) and APRS.   I don't remember ATC ever complaining about seeing my Mode 
C.  I'd put it inside, again.  Come to think of it, that's exactly where I 
put it in N891JF.  Glue a little triangle of 3/32" plywood with a hole in it 
to the top of a crossmember, and stick the antenna in it.  Done, and no 
holes in the outside of the plane.  See enclosed photo...

The PDFs I have show different pin-outs for the 76 vs 76A.

I gave him both.

Hi Larry. If you want to send me scans of (or links to) all the
paperwork you intend to use, I can look at it and tell you whatever I
can  regarding what I would do in such an install. The last Garmin 530
install I did on a Commander 114B had the encoder connected to it, and
it was pretty straightforward (not to be confused with EASY, my least
favorite word). Be Well Mi Amigo

I've been carrying a King KT 76A in my panel for 430 hours and 7 
years and have finally decided to wire it to an encoder (AK-350) and 
power it up.  I think I have all the info I need but I would like to 
verify the "male" pin out layout on the AK-350.  Several hours of 
surfing on the net has provided me with what I hope is the correct 
pin to pin wiring between the units and the pin identification on the 
transponder.  I think I have the pin layout on the encoder but would 
like to verify.   Also, can anyone suggest a good source for the 15 
pin plug that connects to the encoder.  Thanks.

Met with my welder for what I hope is the last trial fit on my new 
exhaust.  It would have gone much quicker, like one day, if I had 
hauled the KR to his shop.  Hope to be flying in a week or so.

 Bob, 
Just to be fair I have the exact set up, but if the upgrade is
not done on the transponder it can go out at any time and it will. They
fixed mine under warranty after 3 years but it could cost a couple
hundred dollars if it is not done by warranty.

Guys,
All the details escape me after a year but as I recall it had to do with
interrogation by mode S facilities. Basically the unit became overwhelmed
by this and confused and shut itself down. Any unit that has at least
revision 7 done to it should be good to go. Mine has operated just fine
since I got it back. In fact it was repaired by the state sides dealer in
Erie Pa. and I had it sent and returned in 4 or 5 days.

[Mark Langford]

I finally got word back on my Terra transponder today...unrepairable.  Parts 
are unavailable.  Apparently those particular components are no longer 
available, and there's nothing comparable.  I have a EE buddy who wants a crack 
at it, but he's pretty busy rebuilding a Yak 52 at the moment, so I'm probably 
going to order a Microair T2000 that will fit in the hole that the g-meter now 
lives in (it doesn't see much action now that I've learned how to land).  

My EE buddy thinks my transponder fairing may have been a contributing factor 
(see http://home.hiwaay.net/~langford/fairings.html ) because he says anything 
touching it will change the impedence, and therefore the load the transmitter 
sees.  I don't know how critical that is, but he gave me a Bendix blade antenna 
that I may substitute in its place.  He says painting the thing may even screw 
it up.  He also pointed out that if the coax is disconnected even for a few 
seconds, that 200 watts has no place to go and can blow something up.  I would 
hope it would be more robust than that, but the bottom line is that mine's dead 
and I have to replace it.  It should be mentioned that the Terra transponders 
have always had a spotty record.  If I remember correctly, Jeff Scott's came 
out of the box DOA, so maybe I should be happy with a good year of service.  
But because that leaves a half sized hole in my panel, and there are a lot of 
things I'd like to change now that the panel is sort of "finalized", I may make 
another instrument panel one of these days...

Mark,
Check with the Microair customer service before you order. If you
remember they have a problem that they are working on a patch. The mode
"S" operation screws them up somehow and you go blind at the most
inopportune times like last week entering class B airspace .

Yes, there's a new "rev 7" version that fixes that.  I'm looking for one of 
those, but it may be a few weeks or months before they're in the pipeline. 
I've sent emails to several suppliers looking for exactlly that though. 
They will also upgrade a rev 6 to a rev 7, but you have to send it off to 
have that done, and I'd rather just do it once.

KR> Transponder Requirements

[Kenneth B. Jones]

The real answer, regarding transponders, is found in FAR part 91.215, 
nowhere else.  Unless you get prior permission from ATC, and if your plane 
is (or ever was) certified with an engine driven electrical system, you are 
not allowed to fly it above 10,000 ft without a transponder. Also, you are 
not allowed to fly in class A, B or C airspace, or above class B or C 
airport lateral bounderies at or below 10,000 ft.  Also, you are not allowed 
to fly from the surface upward to 10,000 ft. within 30 nautical miles of an 
airport designated in Part 91, Appendix D, section 1. (That includes 34 of 
the busiest airports in the U.S.)

The rules are different for planes never having been certified with engine 
driven electrical systems.  The AIM does not accurately reflect the rules 
governing planes which have never been certified with an engine driven 
electrical system.  I think this is a reflection of how complicated 91.215 
is written.

DON'T TRUST WHAT ANYONE HAS POSTED ON THIS SUBJECT, INCLUDING ME.  READ THE 
RULES FOR YOURSELF TO BE SURE!!

KR> transponder connectors

[Brian Kraut]

The 15 pin version with two rows of pins is a DB-15, not to be confused with
the three row version HD-15 as used on monitors.

Best place to get the standard connectors is at www.jameco.com.  This link
should get you there:
http://www.jameco.com/webapp/wcs/stores/servlet/CategoryDisplay?storeId=1000
1=10001=-1=302550

If you can't get that to work go to jameco.com, click on interconnects on
the left, then d-sub connectors, then solder cup.

The other does look similar to the cable on a hard drive. Longer though.

I have on the back of my computer a  2 row female 15 pin connector commonly for

commonly used for such data transfers that such devices use.

You should be able to find these but they may becomming scarce because of the

Are you sure that "18 pin" isn't really  a 25 pin D-shell (extremely common) 
that's only using 18 of the pins to do anything?  The 15 pin might be the 
same way, but 15 pin connectors are also very common.  Have you actually 
seen the connections on the transponder and radio and counted the pin 
sockets, or are you going by a wiring diagram (which would explain the 
18-pin thing)?  Radio Shack sells the connectors and shells that you'd need 
to make one of these (see
http://www.radioshack.com/search/index.jsp?kwCatId=2032058=15=15 
for instance)...

KR> transponder connectors

[Mark Langford]

I should add that I made my cable out of an old "parallel port extention 
cable" by chopping one end off and rewiring with a new connector.  That 
guarantees at least one end is "factory good", and cuts down the workload a 
lot.  You have to spend a little time correlating pins with wire colors, and 
of course double check when you're done, but you'd have to do that anyway. 
This only works if you're not carrying a lot of power through the power and 
ground wires, so I had to make my own radio connector because it required 
20ga wire and the parallel cable was only 24 ga or so.

Yup, I counted them ma-self.  The 15 pin looks for all the world like a 9 pin 
serial port connector that I've wired hundreds of for scale interfaces. The 
other does look similar to the cable on a hard drive. Longer though.  I'll try

See:

http://www.krnet.org/mvn2004/040929271.jpg

I've been flying my KR for two years now and have not gotten around to wiring
up the transponder.  It depends on where your home base is and where you
intend to fly.  Personal choice.

I purchased the Ameriking based on price and it seems to be a quality unit.
Change the batteries every year regardless of what the date is on the battery
or what the reg's say.  I had a battery go bad during the second year and
nearly ruined the unit.

Radio performance has more to do with the antenna installation than almost
anything else.  I use a JRC handheld with an external antenna and I often
communicate with other aircraft 50+ miles out.  I think the JRC is 
the "sleeper"
in the handheld class of radios.  $250 from Aircraft Spruce for the nav / com
unit with rechargable battery pack and non-rechargable pack.  It has all the
bells and whistles you get on the ICOM for less money.  You can even select
the power output you want, low or high, to save battery.  Hook it to 
aircraft power
and 5 watts is all you'll ever need.  I have a two place intercom 
that plugs directly
in to the top of the radio and a push to talk switch on the 
stick.  My only probem in
that area is the high cockpit noise level keeps breaking the squelch on the
intercom.  If I squelch out the cockpit noise I have a hard time breaking the
squelch with my voice.  ANC headset is the only way to go and I have someone
working on a ANC unit for my mic circuit to eliminate my squelch problem.  That
reminds me, I need to give him a call and check on his progress.  The
"Sporty's" handheld is about the same price but has some things that I was
not impressed with.  For example, the plugs for headset adapter on top
of the radio were not standard width so it would not accept the one piece
plug on my intercom that plugs directly in to the radio.

Done right, a handheld setup performs just as well as a panel mount and
you can put the $500 you save in your fuel tanks.

Finally, remember that OPINIONS are worth what you pay for them.

is in the original box and unused.  I got it with my Midget Mustang, but I
have two other transponders already so won't be installing it.  It sells for
$1,349.00 at Aircraft Spruce.  First $1,100 takes it.  Email me direct at

KR> Transponder for sale

[Brian Kraut]

I have a brand spanking new still in the box Garmin GTX320A transponder for
sale.  I have the tray, manual, and connectors it comes with still unopened.
It sells new for $1,263.00 at Spruce.  I will sell it for the first $1,100
including shipping in the U.S.  I will put it on the RV list in a few days
and it will probably be snatched up in hours, but I want to offer it to the
KR list first.

This transponder came with my Midget Mustang when I bought it and was not
installed yet.  Since I am going to sell the Stang soon I don't want to
install it because it will neve increase the value of the plane for what I
can sell it separately for.  I already have a transponder for each of the
KRs so I don't need another one.

[Timothy Bellville]

Can anyone tell me if I need a transponder in my KR2 due to the fact that it
has a battery ignition and some elec. instruments and strobe?
Thanks
Tim

KR>Transponder

[Brian Kraut]

Depends on where you want to fly.  Where you need a transponder is defined
by FAR 91.215.  You can look it up online so I won't repeat it here, but the
basic gist of it is over 10,000' MSL excluding airspace at and below 2,500'
MSL, and within other airspace as designated in the reg that is too much to
type here.

As a practical matter, depending on where you live and where you are based
you can likely be fine without a transponder.  I live in Jacksonville and
have flown to Gulfport, MS without having to bother with restrictions, if I
wanted to go as far as New Orleans a transponder would be a concern.  Other
than that, Orlando and Atlanta are the other areas in my range where I would
need a transonder.  I could land at Jacksonville International without a
transponder with no problem though.

You can get a waiver to fly into airspace and land without a transponder.
The first time I did this I flew into Sanford within the Orlando Mode C area
to visit Colin Rainey.  I simply called Orlando approach on the phone, gave
them my information and expected time, and they gave me an authorization
number that was good all day, simple and pain free.

Aside from the fact that you may not need the transponder it is nice to
have.  On my XC to Gulfport and back I tried to get flight following.  With
very few exceptions, most centers would not give it to me when I told them I
had a transponder.  Several of them said it was not possible because they
could not see me on radar and some said they could see me, but would not
give it to me without the transponder(probably depends on controller
workload and laziness).  I tried to do a touch and go at Daytona Beach once
without a transponder when they were very busy and they said no.  On another
occasion they let me do it, but told me to get the transponder working
before I came back.  For some reason they had a problem with the touch and
go, but said a full stop would have been fine.  Go figure.

One other thing to consider is that a KR does not show up very good on
radar, or at all on TCAS, without a transponder.  That thought crossed my
mind plenty of time cruising along 2,000' over the clouds at 9,000'.  I have
seen jets pass under me and have heard controllers tell jets in my area that
there is traffic at "altitude unknown" at their 1:00 position and 5 miles
knowing it was me.  Those are the times that you wish you had a transponder.

Also, if you get a transponder you will need an altitude encoder.  I don't
know of any situation where you are required to, or would want to, have a
transponder, but not Mode C.

The fact that your KR has an electrical system does not mandate
that you have a transponder.  You only need a transponder if you 
fly your KR into AIRSPACE that requires a transponder.  Does that
make sense? If not, give us more info and your reason for asking?

Transponder and Mode C encoder are airspace requirements not equipment 
requirements. Unless you like getting a special flight permit every time you 
want to fly into bravo airspace, or Charlie airspace, you need and altitude 
encoding transponder.  FAR 91.215 states all Class A, B & C areas must have a 
Mode C encoding transponder to operate in those areas.  This should answer your 
questions.

KR>Transponder ground plane

[Serge F. Vidal]

Just two words on the situation, otherwise you will not understand the
question: I am in Tunisia, my KR2 is in France. I want to prepare my trip to
go there, and I will make a few mods to the aircraft. So, I am now busy
preparing parts, but I have no access to the aircraft now to check layouts,
dimensions, etc.

OK, here is the problem.

The transponder currently installed is a Bendix King KT 76. The transponder
antenna is probably a KA60. The antenna has been installed under the baggage
compartment shelf. As we have debated a few months ago, this is very bad,
because it probably frys my brains. So, I want to move the transponder
antenna to is normal location: under the belly. And I also want to make a
ground plane.

And here are the questions:

- What is the correct size and shape for the ground plane?
- How is the antenna mounted? How many holes, what size? How many contacts?
- How does the antenna contact to the ground plane? Is it through its
mounting washer?
- I intend to make the ground plane with a sheet of aluminum foil, which
will be reinforced by a sheet of Vinyl on top. Must I leave a large hole in
the middle of the Vinyl, to allow the foil to make contact with the washer?
- What can I use to glue the antenna plane to the floor?
Is double sided adhesive OK? Is contact adhesive glue better? Or is it
better to glue the foil to a hard sheet of plastic, and screw everything in
place without glueing? Or is it better to cut the ground plane out of a thin
sheet of aluminum (0.8mm is the thinnest I can get)?

Ground plane... I have some 10" x 11" sheets (4) of double sided copper on

sheets are .022 inches thick, quite light.

 I haven't looked up the right size, but I think it's about 9 inches in
diameter. Someone else can chime in with that info.  Free to whoever needs
one, my KT76 is for sale on eBay, and I'm bailing out of the homebuilt
business.

KR>Transponder ground plane

[Colin & Bev Rainey]

Transponder ground plane is 5 1/2" in diameter, of any thickness and material, 
mine is aluminum, as long as the diameter is right.

KR>Transponder antenna location

[Serge F. Vidal]

In my KR , the transponder antenna has been mounted under the baggage
compartment shelf. Aneat, uncluttered location, with way more space
available than under the seat.

In trying to hold the cost of my KR2S project in line, I want to use a 22"
COM antenna that I have, but need some help on how to create a ground plane
for it. Also, want to do the same thing for the ELT, GPS and Transponder.
I want to put the antennas vertically in the rear of the fuselage, except
for the transponder which I will put under the pilot seat projecting to the
exterior.  I am thinking alum disks would work,  but have no idea as to what
size they would have to be.  Any help or suggestions will be appreciated.

Thanks

Can you clarify this?  My transponder is being serviced.  To legally fly
above 10K I must be using flight following or  ??I cannot file
IFR.

How does one use Flight following without a transponder?

The reason I ask is because 9500 feet in CO is not high enough for me
to fly to Red Oak.

KR> Transponder

[Dana Overall]

Above 10K a operational transponder is required equipment.  I have flown IFR 
with a transponder on the blink so flight following may be possible with 
altitude verifications.  Try it and see, but above 10K you gotta have a 
transponder.  What I meant by my saying 1200 or on flight following or IFR 
was if on either of the two, you will be assigned a code other than 1200.  
Look it up as there may be a provision if you are less than 3000 above the 
ground.

KR> Transponder

[red-bri...@juno.com]

Perhaps I can add some clarification to the transponder issue from an 
operational "real world" perspective. That is to say, from my perspective as a 
22 year ATCS at Indy Center.

Yes, you are required to have an operational transponder with mode C above 10K, 
both IFR and VFR. If you are IFR and your transponder fails in flight, you can 
expect to be assigned victor airways and or compulsory reporting points and 
handled as a non-radar flight. This is especially true for an aircraft such as 
a KR which will have very little primary (non-transponder) radar return. Also 
bear in mind that, although the controller is still required to provide you 
with IFR separation, beyond the minnimum requirements, the level of service you 
will receive is at the descresion of the controller and may be subject to other 
operational concerns from an ATC perspective.

If you are VFR in a KR without a transponder, don't expect much in the way of 
flight following, especially from center, as our primary radar is poor at best. 
In fact it may be non-existant in many areas, especially at low altitudes. This 
is why my KR will have a transponder with mode C despite the weight concerns.

I hope this answers some of your questions.

KR> Transponder

[ron...@pcisys.net]

Thanks for the info on transponders.  I got good news today that
my transponder has been fixed and I asked them to "next day" UPS
it to me.  Should install Wednesday and be able to fly at 11,500'
13,500' or 15,500' as I choose!

I did a seated "happy dance" when I got the news.  As much as I 
have avoided ATC services in the past, that is changing as I fly
more.  Flight following...YES.  Traffic advisories above my 
airportYES.

KR> Transponder

[Ross Youngblood]

Thanks for the Xponder info...
I have a nice little Terra Mode-C unit with an
encoder from another vendor... need to get the
system calibrated soon, but the Terra unit takes
up very little space (1/2 width of a normal radio).

So my Xponder and Com radio take the same panel space
as a standard radio.

Too bad Terra is out of business...
