The next open day at the Signals Museum at RAF Henlow is on Saturday, September 5.
Volunteers welcome visitors as they go on air with the Amateur Radio Station, GB4SMH, from 10am until 4pm.
Visitors should go to the guardroom at RAF Henlow with photo ID, passport, driving licence or over 60s bus pass to get a free entry ticket.
The museum dates back to 1999 when a new home was needed for the small collection of radio and electronic memorabilia from the defunct museum attached to No. 1 Radio School at RAF Locking.
The Commandant at RAF Henlow at that time, Air Commodore Mike Davison, had in previous years also been the Commandant at Locking and was keen for the collection to find a home, preferably at Henlow which has had good links with radio, radar and electronics for many years.
Mike recruited S/Ldr Howard Newbould to implement his idea.
At the same time the museum received a generous donation of surplus equipment from the RAF Museum Reserve Collection which was moving from nearby RAF Cardington to RAF Stafford. Visit www.rafsignalsmuseum.org.uk
