SARC won the original GB4FUN unit from RSGB and renamed it with the new call sign - GB4HAM Radio Communications Unit which suited it quite well to its function.This was used to promote Amateur Radio and was well known around the UK and in the USA . The GB4HAM (RCU)  has now been converted and mounted on to a Heavy Truck Chassis and re-named with a new call sign  GB4HAM (Radio Communications Unit). Transportation of the unit is now more stream lined , takes up less space and easier to handle. 

The new GB4HAM (RCU) is now owned by Steve Webster M1ERS and is used to promote Amatuer Radio in general and also to promote both the Sheffield Amateur Radio Club SARC and the Sheffield D Star repeater group for GB7SF. The unit can be seen at events up and down the uk,
