What do radio waves turn into if given enough time?

or do tehy stay forever as radio waves?

Can they flat line? If so what happens when the wave length goes flat?

Update:

typo: or do they stay forever as radio waves?

    They stay radio waves until they are reflected, refracted, or absorbed.

    They stay radio waves forever.

    Yes, they will remain as radio waves. The wave length will get longuer and longuer and longuer (red shift). So they will be radio waves forever unless you define a new type of wave located lower than radio on the spectrum.

    Given enough time, and if they are not broadcast in a 

    very tight beam, radio waves will turn into indecipherable garbage. 

     

    They may be recognizable as being artificial signals from afar, 

    but they will have been decimated by the background radiation 

    and radio noise of the Universe itself, and everything that is in it.

    The wavelength doesn't change. A radio waves stays the same forever.

    They get buried in the cosmic background radio noise.

    if nothing absorbs them, they go on forever as radiowaves. The wavelength stays the same, the intensity/fieldstrength/amplitude goes down according to the square of the distance

    Radio waves go on forever at the speed of light

    The only problem is with distance the get more spread out

    Radio waves out in the Universe have their wavelength "stretched" along with the expansion of the Universe.  So their wavelength gets longer and longer.  This results in a loss of energy, but they never completely die out.

    like light, they eventually degrade into heat. As they hit surfaces, some is absorbed as heat, some is reflected, which eventually hits another surface, etc. 

    "wave length goes flat" ?? sorry, that makes zero sense. 

    if there are no surfaces, eg in outer space, they can travel for very long distances. But the inverse law applies and the signals get weaker and weaker until they are lost in random movements of the few molecules in space.
