transponder

Came out of my own airplane for a panel upgrade. Worked flawlessly prior to removal, I have witnesses that are registered users here as well, if needed. Display is 100%, no dead pixels. The condition is mint. Unit was purchased directly from Garmin and spent only 18 months in the panel until a...

I'm a former Navy and small aircraft pilot, and now fly unpowered paragliders in the Seattle area. I'm interested if there are small lightweight transponders a paraglider could carry to simply squawk 1200 to show up on our local Seattle Approach radar. I've ridden thermals to 15K' and had 6+...

Over the past year I've noticed the pressure altitude reported by the transponder is routinely off by 100' when compared to my altimeter when set to 29.92. In every case it reports me being 100' lower (never higher). On some rare occasions it's been 200 feet (since there is only 100' resolution...

Hello All- I'm having a 750xi installed in my Archer, and am wondering how to reconfigure the data buttons that are used for transponder and audio. I'm just using the demo on my PC. I don't have a Garmin transponder, nor a remote audio panel, so I would like to use those buttons for other...

Trying to get used to glass in the cockpit after being away for a few years. Does the 430 have the transponder built into it like (I think) the 9000 does? Thanks.

How to enter "Configuration Mode" on a Bendix King KT 24 transponder? I need to check and possibly change some communication parameters.

My Narco AT-150 went poop. Bench test says that it isn't repairable. I'm not quite ready to do a complete upgrade (already have ADSB out) on the transponder but think that a AT-165 side-n-replacement is a good option right now. So if anyone has done a panel upgrade and has an AT-165 lying...

Rather than restart an old thread on Transponders (6yrs), I'll start fresh. It has been years since I've been on POA. Recently moved (returned after 38 yrs away) to Southern NH. I will need a shop this spring for 24 month transponder check. Searching GoogleFOO does not reveal much. Any...

My Narco transponder Is on its way to greener pastures. I’m planning a panel upgrade to G3X Touch (experimental), but I’m not ready to do it all yet. Ideally, I want to replace the transponder now, and reuse it when I do the full panel. The GTX 45R is what I was planning for the...

Narco AT 155 TSO transponder. Worked without problem when it was removed for a panel upgrade. What you see is what comes with. $100 + shipping OBO.

Hello, We removed our KT76c and SSD120 for an upgrade. Everything was working before removal. $350 plus shipping for both the transponder (Includes Tray) and the encoder.

Everything you need in a transponder setup except the antenna. This includes a KT78 TSO transponder, tray, ACK Model A-30 encoder, coaxial cable, wiring harness. I got Appareo's ESGi I/O last weekend and preserved the wiring & tray to make it easy to reinstall. Great for experimental or setup...

Hi. I have been using Avare for more than 5 years & it's been very stable. Now im thinking of adding an ADSB in I heard a lot about Stratux If anyone is using Stratux on an Avare, I could clear some doubts. 1.Does this connect only via WiFi or it can connect via Bluetooth too. 2.Does this...

On the Aircraft Spruce website the FAQ for the GTX 335 says that a software update is in the works for using the 335 as a WAAS source for a G5. According to the Garmin website, they are on version 2.12 now. Does anyone know if the updates allow it to be used as a WAAS source? Can you use the...

I'm pretty fresh to learning about the nuances of ATC and want to know why ATC assigns squawk codes in the first place. I've seen pictures of an ATC's radar scope, and it includes the ICAO airline designator and the flight number. Without a squawk code, would that information still be there? If...

So this is an odd one. When flying now ATC is telling me my transponder is reporting an altitude about 2500 feet too high (and they haven't been too happy about it, either). I figured out, however, that if I pull the breaker on my Air Data Computer, the problem goes away... WTH?? These 2 things...

As there is only one very busy avionics guy at my airport, it helps a lot if I can debug things on my own... hoping someone can point me in the right direction. On my last flight ATC kept telling me they were seeing me on radar at around 6000 but I was at 2000-2500 at the highest. I cycled the...

Hi guys. I have installed a KT76A classic transponder on a 1957 C172, did a bench test on it at a shop about 2 months ago and it was just fine. Last week I flew and was told by atc upon arriving to the terminal area the they were not getting my transponder, just raw primary radar, I cycled my...
