Does anyone know if that practice still exists, and what frequency it
is?

Thanks.

Buck, that was probably the trans-Atlantic link at Gander, Newfoundland.
That airport was vital to trans-Atlantic planes as a refueling stop back
in the days when planes couldn't make a crossing from the states to
Europe on a carried fuel load, so they refueled there for the trip
across. That hub then became important as the tracking center as a
result. Once planes could make non-stop long distance flights, the
airport declined and with it the role of reporting station. The airport
was vital on Sept 11, 2001...handling and landing over 40 trans-atlantic
jets when the grounding order came.

The MWARA centers (Major World Airway Routes Areas) still use the
shortwave bands. Gander (VGA) is still active I think, as well as
Azores and Iceland radio. I haven't heard the station in Ireland for
some time (used to be Shanwick?).

Someone here will have the freqs.
