Heaven's Radio is a gospel song recorded by the Carters in 1940. Stamps-Baxter music copyrighted a song by Brumley title "Heaven's Radio Station Is In The Air" in 1943. Not sure if there's a conncetion.

From a 1942 book: Such items as a Negro woman singing a song she composed called "Heaven's Radio" in which the words are the expression of a simple mind.

The song was refernced to a Freddie Lee Kirby who was a black choir director in Texas during the 1930s. [Popular Song Index: Third Supplement By Patricia Pate Havlice Published by Scarecrow Press, 1989]

There's no direct source I could find. Anyone?

HEAVEN'S RADIO Carter Family

There's a wonderful invention
It's called the radio
You can hear it every where you chance to go
But the static in the air
Sometimes makes it hard to hear
But it is not so with heaven's radio.

CHORUS: Heaven's radio on the other shore
For my precious savior always listens in
It's the same old radio that was used long time ago
For my precious savior always listens in

Daniel in the lions den
With this power should surely win
For my precious savior always listens in
And I know without a doubt
Honest prayers will bring you out
For my precious savior always listens in

Well He set the Hebrews three
From the fiery furnace free
For my precious savior always listens in
He will rescue you today
In that same old fashioned way
For my precious savior always listens in
