The box draws about 200mA at 12V.

I know this is a pipe dream and there are probably all sorts of reasons it's not possible...

Would it be possible to multiplex the XPDR antenna with the ADS-B box in some fashion?

RF is *not* my area of expertise, so I have no idea if this would work or not, and why (or why not)...explanations welcome for my own edification

Yes, it is possible to use a multiplexer to combine the signals into one antenna. But it isn't cheap, like $1000. That can be good for certified planes where adding an antenna is an issue, but for experimentals it's generally cost-prohibitive. It also means the antenna isn't optimal for at least one of the bands.

It's my understanding that with the Dynon 261 transponder future software update that both 1090 and 978 traffic can be received on a single band 978 receiver as well as standard mode c traffic! Is that correct?

The transponder update will be out at the same time the ADS-B receiver ships, and yes, this makes the Transponder DO-260B certified, which allows you to see 1090 and 978 traffic on just a 978 receiver.

In areas with radar coverage you'll even see Mode-C aircraft.

Excellent!! Been waiting for this..nearly full traffic and weather for under a grand and NO monthly fees. Way to go Dynon!

Put me down for one of them too! I need some LNAV guidance as well (approved for IFR).

How will the transponder firmware update occur? Is it part of a software release for the Skyview system whereby the transponder will be updated through the normal skyview network, or will the transponder need to be sent to Dynon for update? Something else entirely?

The transponder will update as part of a normal firmware release. You'll need to go into a menu and press an extra button and the power cycle the transponder, but that's it. You don't need to take it out of the plane or do anything drastic.

No charging for updates or making you mail it in to the manufacturer here!

Except for that little SNAFU with the servos that had to go back so they could accept Skyview...
