Bare Bones Low Cost ADSB-OUT
 

Members,
My plane is already set up for ADSB-IN with Garmin GDL39
I want a simple OUT solution.
I already have a GTN650 that was installed with a new altitude encoder.

I am thinking a used GTX330ES would be my easiest solution.
Would I need any other hardware? Air/ground switch or any odd stuff like that?

thanks

A Trig TT22 is probably the cheapest and easiest solution. It has a built-in altitude encoder.it can be wired up in about an hour and only needs one wire from an external source besides power and ground. I have never had a problem with one of these, and I have installed a bunch of them.

Or a Freeflight RANGR Lite UAT out only model. It can use your GTN as a WAAS source and has a built-in digital encoder. Will work with legacy or digital Mode C transponders. Right at $2K if you do it yourself.

In fact you could pick up a used Navworx model and run it legally since you have a panel mount WAAS navigator source that negates any proposed AD action. I bet they would be very cheap on the used market right now.

Another option
 

If your current transponder is a King 76A you may want to look at the Trig TT31. It has the same dimensions as the 76A and will work with the old transponder's encoder. It does require a squat switch which is about $125 if I recall. John

Pretty disappointing options.
 

These "cheap bare bones options" aren't very cheap!!! Are we really going to have to spend 2000 minimum to get adsb compliant?

Yes.

There's still 3 years left. I'd be willing to bet there will be some less expensive solutions by then. The technology already exists and is evolving rapidly, largely thanks to UAV's.

I plan to wait until close to the deadline and aim to spend less than $1k. My Stratux box works great for now (yes, I know it doesn't show all traffic - I use it mainly for wx) for adsb-in. Since I will install myself no need to worry about an avionics shop backlog.

At this point, yes. The $500 rebate helps some too. There was a cheaper option (Navworx), but for some reason the FAA picked on them. I know there were problems with NavWorx, but it could have been solved without threatening an AD to require removal, which effectively shut the company down for an indefinite period of time.

I think time may be on our side allowing technology to develop. The ADSB thing is world wide and some of the products other countries already have are proof of that. If you look up www.uavionix.com/products/echo-att-20b/ you will find a UK approved, manned A/C In and Out ADSB for the equivalent for $750. which meets the UK spec. and is presently available and on Amazon! Now that still needs FAA approval for US and I guess even for the experimental market but at that price and availability someone will challenge the FAA to approve it. And they may be successful at that differential in price.

I just got an email from above link that said :

Hello Dennis,

We will be announcing a new product at Sun'N'Fun for use with Experimental and LSA aircraft.

Stay tuned!

Yes you probably are. Don't think I've seen ADS-B Out compliance anywhere below $2000.
