The Signals Museum at RAF Henlow is hosting a special opening this weekend to coincide with a global event.
The volunteers will be taking part with the Amateur Radio Station, GB4SMH in Museums on the Air, and will be hoping to link up with other museums in the UK and Europe who are taking part, on Saturday, June 18 and Sunday, June 19, from 10am until 4pm.
The museum is open to visitors on both days.
You will need to go to the guardroom at RAF Henlow with photo identification such as a passport, driving licence or over 60s bus pass to get a free entry ticket.
The museum will be open again on Saturday, July 9, a week later than usual.
