After the cold war ended, shortwave radios gave way to television and the internet, and the broadcasts were wound down.

冷战结束后，短波收音机让位于电视和互联网，广播也随之减少。

It's a shortwave radio channel. It might be still working.

那是短波，可能还有作用。

It turned out that because Ove's house now lay exactly on the municipal boundary, clearance from the command center was required on the shortwave radio before they could get to work.

原来，欧维的房子正好落在两市的交界处，有关部门需要先通过短波澄清责任，在这之前，谁也不能灭火。
