What can be done to combat the un-Islamic aspects emanating from these radio stations?

Answer

Evil is o­n the ascendancy. This has been predicted by Rasulullah (sallallahu alayhi wasallam). As we approach the confines of Qiyaamah, we shall be the witnesses of tumultuous evil and immorality. And, in the Muslim community this evil will be spear-headed by those known as ulama— the ulama-e-soo’ (evil learned men masquerading as muftis, molvis, shaikhs and khalifas.

Whatever is in o­ne’s ability and lawful, o­ne should do to combat the evil of these media. The concerned Muslim will discharged his obligation of Amr Bil ma’roof if he gives naseehat in this regard to whomever he is able to. Allah Ta’ala is the Final Arbiter.
