The WT does have a radio station.
I read about it years ago.
WBBR
A quick search of the WTCD found it for me.
Is it still going?
Radio Station WBBR Preaches the Word
Jehovah’s witnesses now declare “the day of vengeance of our God” and at the same time “comfort all that mourn”. (Isa. 61:2) This message of judgment upon the nations and of comfort to the mourners is being published in all the world unto all nations by God’s faithful Kingdom publishers who are ministers of the gospel, by the printed page, by word of mouth, by correspondence and by radio. Outstanding in the field of radio is the Watchtower station WBBR, in New York City.
Many have been the attempts by the misguided servants of darkness to still the voice of this, the only radio station on earth dedicated wholly to the service of Almighty God; but after twenty-six years of uninterrupted proclamation of the Kingdom message giving unstinted praise to Jehovah, WBBR goes confidently on sharing with all other Theocratic instruments the protection Jehovah has promised to his people.—Isa. 54:17, Am. Stan. Ver.
This station being confined to a building, and its voice not being strong enough to reach into all lands, it is unable to fulfill the divine command to preach this gospel of the Kingdom to all nations. The overspreading of the earth with the gospel message is done by the entire body of gospel preachers, Jehovah’s witnesses, as they actively publish the truth in all nations. However, WBBR does have a rare opportunity of preaching to many persons from many nations.
WBBR’s voice may reach some or many of the official representatives of nations, because of its location in New York city. How so? Why, because the focal point of the largest gathering of national representatives ever to exist on earth is New York city. The nations gather there representatively in a United Nations organization. And WBBR has a message that should vitally concern the United Nations, because God’s Word speaks of such international attempts to rule the world, and WBBR preaches that Word.
Over nineteen centuries ago Jesus gave warning of the coming of this great council of nations with its religious backing and said it would presume to stand in the holy place, claiming to be divinely authorized, but in actuality it would be a dreadful desecration under the guise of the political expression of the kingdom of God on earth. “‘So when you see the dreadful desecration, of which the prophet Daniel spoke, set up in the Holy Place’—the reader must take note of this.”—Matt. 24:15, An Amer. Trans.; Ps. 2:1-9.
At the time this great kingdom counterfeit come into prominent view there is to be a mighty world-wide proclamation regarding the true kingdom: “And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.” (Matt. 24:14) The desecrating counterfeit has come into view; God’s people are taking note of this. And WBBR is preaching it, at the very doorstep of the U.N.
Not only are the official representatives of many nations within reach of WBBR’s radio signal, but also there are millions of individuals speaking the languages of the various nations, many thousands of them being foreign-born. The iron curtain may be down between the good news of the Kingdom and those nations behind that iron curtain, and may hinder though not stop gospel-preaching in those lands; but there are still in the great metropolitan center of New York city, WBBR’s primary area, according to the last census, 926,516 Russians; 412,543 Poles; 322,586 Austrians; 123,188 Hungarians; 57,624 Czechoslovakians; 84,675 Rumanians, and 11,355 Yugoslavians.
We might look to Palestine, with its 1,912,000 inhabitants, when we think of the good news of the Kingdom going to the Jews of the fleshly house of Israel, and yet incline to ignore the fact that there are “2,035,000 Jews in New York city alone. We think of Rome as being the city where most Italians would be found in one place; there are 1,500,000 inhabitants in Rome, yet in New York city there are 1,095,000 persons, Italian-speaking or Italian-born. There are 506,635 people in Dublin, Ireland, where the kingdom message is greatly opposed by the Catholic clergy, yet there are 518,466 Irishmen in New York city alone, where the Kingdom message is freely broadcast by WBBR. And while in Greece Jehovah’s witnesses receive diabolical persecution at the hands of false religionists, from WBBR the good news of the Kingdom is within easy reach of 53,253 Greeks residing in the city of New York.
WBBR is indeed a powerful instrument in the hands of the Most High God, privileged to preach not to all nations, but to many individuals from many nations.
