Sorry Bob but that is wrong information! The short version of what SmilingJack posted,
taken from information provided by AOPA as of today:
"Countries with ADS-B Out mandates and proposals:
Canada. Currently no mandate, but operators who voluntarily equip with 1090ES (particularly in the Hudson Bay and nearby oceanic airspace) can receive a higher level of service. Nav Canada is part of a joint air traffic surveillance venture, Aireon, installing ADS-B equipment on low-earth-orbit satellites. Nav Canada will be the launch customer when the service becomes available in 2018, and initially intends to incorporate 1090ES ADS-B into North Atlantic airspace.
Mexico. 1090ES required beginning January 1, 2020, in Class A, B, C, E above 10,000 feet msl, and other specified airspace. Requirement effective now in Class E airspace over the Gulf of Mexico, at and above 3,000 feet msl within 12 nm of the Mexican coast."
Notice both require ADS-B OUT on 1090MHz. Eventually every country will require ADS-B OUT in some form or another. None of them are providing ADS-B IN data.
The Bahamas has not published any timeframe for ADS-B implementation but, given how important US General Aviation is to their economy, it wouldn't surprise me if they wind up accepting 978MHz OUT. Only time will tell.
