GB2MOP is the call sign of “Internal Fire - Museum of Power", located at Tan-y-Groes, near Cardigan in West Wales. 
The Museum’s core collections chart the history of internal combustion engines, particularly large diesels in Industry and transport.
A new Motorcycle Collection, Thermodynamics Lab and an Area dedicated to Trinity Lighthouse is now open. Click here to go to the main museum web-site for details of steaming days and other museum events. 
This site illustrates the museum’s growing Maritime Radio collection comprising three working ship’s Radio Rooms covering the period from the 1950s to the 1990s, as well as an extensive valve collection, Titanic feature and Sunderland flying boat wireless operator’s position. It is well worth a visit for the Radio collection alone!  
As with the engines we try to keep all the radio equipment operational, we are frequently on the air using the museum’s own call sign: GB2MOP.
