Yugoslavia had more than one radio station broadcasting computer programs - Ljubljana's Student Radio would also broadcast Spectrum software, my father recorded almost all of it so we had over 30 cassettes (he probably still keeps them :P ). A friend had a doorbell that would very briefly disrupt the electrical current in their house so he would stand at the front door to make sure noone had to ring it during the broadcasts :D
