Thanks ETOPS,
FWIW. Lynx said "....The Pilot Aware Rosetta does not transmit ADS-B out in its own right. It can provide GPS to a suitable ES Mode S Transponder, to give ADS-B out at Sil 0, which means uncertified ADS-B out. "
So smooth coversage isn't definite if "I" choose stuff based on the Flyer pages conflicting 'expert' contents this week !
The 12 hr battery & attracive SE2 OUT is self contained and conforms to a growing state supported UK.,US Canada standard method.
So far so good, but to translate its potential ADSB IN then requires another firm's offerings.
One such I read up demands a regulated 5 volt 2 amp uninterrupted supply and recommends one buys "a good cigarette socket device".. Which I'm left to acquire.
I do realise you do have it sussed, perhaps in the end one copies someone else: though workable it remains a rather Heath Robinson solution !
It needs a minimum of three or more separate components, plus wires and blue tooth etc. - all for obtaining a DIY fledgling EC scheme. It's deffo cobbled together.
Lynx meanwhile have kindly offered to demonstrate various conglomerates they sell to potential purchasers visiting Turweston, which could provide a sort of way through.
By example of a single'together' solutuion to a pilot's instrument take my EFIS. A complete system arrives, fits a standard 2 1/4" panel hole & only needs a 12 volt feed, it comes with quality plug/socket connecting lead to its remote GPS head. All self contained , all from one maker & works without compromise.
Apart from being kind to others SE2 alone isn't really enough, fees for proprietry translating gear use don't appeal either. Effectively that's a tax on safety,
Shirley our CAA want universal in/out implementation ?
Now it's a confusing time, one wants to do the right thing however it's too early yet to find any single make whole solution, in the interim it's a DIY Beta effort using cottage industry products.
