From Becker data sheet:

The BXP6401-2-(01) is a compact and lightweight single block Mode-S transponder. It is certified according to ETSO-2C112a and is suited for VFR and IFR operations up to 15.000 feet.
The transponder is equipped with extended squitter and SI code function and it provides an interface to the central aircraft data system. It allows ELS, supports EHS, as well as ADS-B via extended squitter.

I have FAA AC 20-165A (ADS-B Out requirements). There is no reference in this document titled class 1 or 2 transponders.

Seems to me Becker designed this unit for ops below 15,000 feet, including ADS-B. Why would it have an extended squitter if this were not true?

It's in the document you mention... just hidden as minimum output power requirements in a chart on page 30.

And having the appropriate GPS source to generate the correct values for SDA and SIL to not lose traffic this coming January.

Looks like to Dynon beat me to it.

David,
Becker is a European company. The E in ETSO stands for Europe. Yes, they have different rules than the US.

Becker responded - they have an upgrade for my transponder being certified. No cost estimate at this time.

GRT has GPS box coming this fall that will meet ADS-B rqmnts and serial port into Sport EFIS - about $500.

So - we have 4 years to go and this may all work out.

If only this whole ADSB thing was that simple. You will have to wait and see, and hope, that the GRT will output the gps data in a format that your Becker can read. Unfortunately there is no universal standard.

You can add ADSB-in (not required) at anytime, for about $500. Good for weather, and limited traffic.

I am afraid you can expect the Becker upgrade quote to surprise you....

For comparison remember that GRT will sell you a remote mounted TT-22 transponder which meets ADSB-out requirements (and I hope will talk to their GPS) for $2.2K. Subtract what you could sell the Becker for, compare to their upgrade quote.

or anyone who knows the rules:

For ADSB-out compliance, is it allowed for the approved (e.g., meets the standards) gps signal to "pass thru" an uncertified box (like most EFIS boxes) on its way to the transponder? Or is a direct connection required?

I watched Denys fly the Gipsy Moth in Out of Africa for the umpteenth time last night and thought we are living at the end of a wonderful era.
Flight freedom as we have known it is ending. The box is getting smaller and smaller. The change is gradual but it is relentless. When all the technology behind ADS-B is fully implemented, there wil be no freedom of flight, every minute flown will be a matter of government record.
We have indeed lived through wonderful times in aviation. It will never be the same.
