Small shortwave radios with built-in antennas are next to unusable in urban/semi-urban areas these days, unless there also is power outage shutting down all of those local emitters of RF noise. Witnessed that last winter when we had a six hour power outage - the SW/MW radio could suddenly receive quite a few broadcasts again. And then you realize that these days mostly China and some american religious organizations invest heavily in shortwave broadcasts.
