Occasionally I have listened to WTWW's signal, and like the fact that the station plays more than the usual preaching. I have fond memories of WRNO, superpower KUSW, and KYOI (Saipan) playing pop/rock on short wave. Radio Luxembourg's services on 6090 and 15350 were others I enjoyed as well.
Over the past few years, some countries have altered their rules, or at least have allowed lower powered short wave broadcasters to broadcast. Germany has a few, and Denmark has one, and Australia has a few domestic broadcasters. These tend to be community or non commercial type radio stations that play oldies or pop/rock music. Some stream online, and those that don't can be heard on remote receivers that are nearby. Have any of you listened to these?
I could see something similar to that taking place here. It would have to be more of a hobby/labor of love/community style radio station. Face it: Short wave listeners tend to be a different breed of people than AM/FM listeners, and there are fewer of us these days. It was Joe Costello of WRNO who challenged the rules regarding domestic/international broadcasting and got his station on the air. A low power SW service would be novel here. Call it "propagation research" and use digital modes like DRM or other modes that may be created. Just an idea.
