Late reply to Martin:
I very rarely see FLARM targets, but I also don’t fly near areas known to have gliders. I mostly use the Sentry now because of the CO functionality.

Probably because the SkyEcho doesn’t have FCC approval. Technically you can use it in receiver-only mode and nobody would know the difference.
Still have just Mode S. CAA cash ends 31/3/22. I hear Canada is requiring ADS-B out to go up as well as down for satellite reception.
No idea what EU or CAA will require. (But they will likely be different.)
I’d like to fit something.

Thanks Dimme; so it would not be possible to use its ADS-B Out capabilities in the US, right? I mean legally.

Can you even do it technically, given that the US and Europe have chosen different standards for ADS-B out?
The RSA are have an agreement here with an outfit called " Flying Neurons" and have an offer at the moment where groups can get together and buy the system in bulk through the RSA. Of course the more aircraft and clubs commit to buy the cheaper the system becomes.
This is an an traffic warning system which shows all transponder traffic as well as Flarm.
As an EFB we have SDVFR which as a base is free and has enough information to satisfy a PPL examiner. It can also be added to by buying further charts which I believe now cover the whole of Europe.

Yes, with a mode-S transponder with extended squitter (and I know quite a few planes in the US that switched to a new mode-S transponder when the ADS-B mandate came in). It’s UAT that’s specific to the US.

Isn’t it just that the USA gives one the choice between UAT (below 18 000 ft only) and Mode S ES (Extended Squitter), and Europe requires Mode S ES? So by installing the same Mode S ES, one is compliant in Europe and USA (not necessarily Canada because of the diversity (two antennas) requirement)?

I understand that Sentry (now) works fine in both the USA and EU/UK; if so it seems that technically it can be done. But perhaps I’m missing something? 
.. and today the Sentry Plus was released with support for Flarm (and other things). Looks nice, will only work with FF I guess.

Blimey; for a long time I hesitated between the Sentry and SkyEcho 2. Really liked the features of the former but opted finally for the latter because of the FLARM support. Yesterday ordered the SkyEcho 2 and today saw this; fortunately, I was able to cancel the order
