Hello,
I assume you are referring to broadcasts from England? Not broadcasts in English language? Most radio broadcasts in Alaska are in English.
There is a statewide series of repeaters that rebroadcast NPR and other Alaska Public Radio programs statewide. You can also listen online to AKPRN broadcasts here:
http://www.alaskapublic.org/Commercial and religious stations also exist in the Bush. Some regional hub villages have their own radio stations that are quite popular in certain areas, and have programming as varied as rap, rock, country, polka and bluegrass. Among the most interesting are the shows that have existed for many years and pre-date rural phone service and in the Internet called "Bushline" or "Open Line" programs. These handle messages phoned in or emailed (or Tweeted) for "happy birthday" greetings, get well wishes, and "shout outs" from people in Village X to people in Village Y. There are also sometimes shows that offer local items for sale that listeners send in.
As far as shortwave broadcasts, reception is often quite good, and we know many Alaska residents who have "ham" sets, or listen to portable multiple-band radios to see what is being reflected off the ionosphere.

Neither Sirius nor XM offer service officially in Alaska, but many Alaskans we know have used addresses in the Lower 48 to buy a satellite radio and do get some portion of the broadcasts. Sometimes it's great. Depends on view of the Southern sky, basically. The farther North you go, the spottier the reception. I used mine in Unalakleet (near Nome) and got most of the stations.
Hope this helps. If I am missing some part of your question, feel free to restate it.
Regards,
John
