station started transmitting in 1979 and currently broadcasts on 15476 kHz shortwave and 96.7 MHz FM. It is one of the southernmost radio stations in the world and its range signal includes audio identification in multiple languages. The host of "Panorama Nacional" Marcelo Ayala told at the beginning of 2024 about his life experience and broadcast by LRA36 Radio Nacional Arcángel San Gabriel.
A
wind generator was installed in 2008, mounted by
INVAP.
The 43 buildings of the station have a combined space of covered; of fuel are used annually by the four generators to produce electricity for the station. Research projects include:

. Shortly afterwards, Argentina issued a diplomatic apology, saying there had been a misunderstanding and the military commander on the ground had exceeded his authority. Despite this initial outward show of deference, the party was later welcomed back to Argentina with a hero's welcome. In the meantime, the ''John Biscoe'' had returned from the Falklands with a military escort and completed rebuilding the British base.
The
Antarctic Treaty of 1959 now treats the continent as a laboratory open to all, and provides that "no acts or activities ... shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty."
People
The base was the birthplace of
Emilio Palma, the first person to be born in Antarctica. There have been at least ten other children born at the base.
Climate
Like the rest of the Antarctic Peninsula, the base has a polar climate characterized by strong winds that descend downwards from the
Antarctic ice sheet.
These winds can exceed , leading to
blowing snow and reduced visibility.

General Martín Güemes Refuge
Refuge General Martín Güemes is the name given to two shelters in Antarctica. The first one is covered by ice, the second one is active. The refuge is Administered by the Argentine Army and depends on Esperanza Base, which is responsible for maintenance and care. The two refuges are located on the Tabarin Peninsula on the eastern tip of the Trinity Peninsula

on the Antarctic Peninsula south of Esperanza. The refuges pay homage to Martín Miguel de Güemes, a military man who served an outstanding role in the Argentine war of independence.
General Martín Güemes I Refuge
The first refuge was located on the north east coast of the Duse Bay of the Trinity Peninsula and opened on October 23, 1953. , at that time head of the newly created Esperanza Base, participated in its construction, being one of the first refuges installed by the Army and the second in the continental Antarctica. The refuge was destroyed by the ice in 1960.
General Martín Güemes II Refuge
The second refuge is active and is located in the Tabarin Peninsula and was inaugurated on September 15, 1959. It has capacity for six people, food for a month, fuel, gas and a first aid kit.[ :es:Refugio General Martín Güemes]
