Before I had broadband I was in much the same position, there were internet stations on
Real Audio which I couldn't get at all and some on WMA which dropped out frequently. I always
record anyway because most of the broadcasts from Europe or the USA are at the wrong time for
me to listen 'live.' My software displays the recording as a waveform and the dropout portions
show up as flatlines so, with a little care, it is possible to eliminate those sections by
highlighting and deleting them as one does with text. Of course, if the dropouts are VERY frequent
it can be a real pain to get rid of them all, but it IS possible and I did it for several years.
