A museum charting how radio communications have developed over the past century is facing the threat of closure.
Part of the Orkney Wireless Museum, owned by Orkney Islands Council, is up for sale. The museum is one of only two of its kind in Scotland and campaigners fighting to save it fear for its future.
The facility brings to life how much the world of radio communication has changed over the past 100 years.
Amongst the items on show are vintage military equipment, a fine selection of the wireless sets which once graced homes across the Islands and even Orkney's very first jukebox.
The problem lies in the store room, the building where exhibits not currently on show are kept under lock and key.
It is home to several hundreds of old radios, forming the bulk of the collection. It has been put up for sale by Orkney Islands Council - and the volunteers running the museum been given notice to quit.
Without somewhere safe to store the radios, the future of the entire museum is now under threat.
Bill Wright from the Orkney Wireless Museum says the threat is very real. He said: "I think it probably is the most serious crisis we have come up against so far. We have been going for about 25 years now and this if the first time we are having to face closure."
Wireless enthusiasts say that shutting the museum would be a big loss for visitors.
