On March 7, 1935, Munia Zafransky landed at Haifa.

Munia Adam was one of the first radio operators of the Haganah.
He built the first radio stations in the חומה ומגדל‎ Tower & Stockade settlements, and for various Haganah units.
He set up the communication systems for the first vessels of the Maapilim.

Munia Adam became the chief technician and instructor in the communications department of the Haganah.

In 1937, Munia Adam participated in the first course in wireless communication of the Haganah, in Tel Aviv.
He built receivers and transmitters according to the technical data that he learned from books.

By 1939, Munia Adam had built 36 stations throughout the country, as per order of the national headquarters of the Haganah.
He went with the Tower and Stockade settlers, and set up the station, while they were busy with their details of settlement, such as Kfar Menachem, Hanita, Shamir and Tirat Tzvi.

Munia Adam was personally involved in the sailings of 13 vessels; several of which sailed more than once.
The first vessel was Poseidon B, in May,1938, and the last was Tiger Hill, in August, 1939.
Then Mossad leAliyah Bet cut its connection with the Haganah for logistic reasons.
Munia Adam kept a complete record of how and what he did on all of the ships that he handled and in his book, with details of
his work.
Munia Adam described how they would leave for ships in the darkness of night, and perform diverse and misleading moves to make certain that they were not being followed; tThey used music and songs and other tricks to initiate contact or to warn of contact etc.

Palyam.org cites "When Charles de Gaulle and his men set up the Free French underground radio station, Munia was the one who set up the station for them, as recommended by the Jewish Agency.
The first year that the station began broadcasting, it did so from Haifa and it was Jews who ran the station."

was forced to give up contact with all of his friends.
