The first job to tackle was replacing the HF Radio transmitter/receiver with a unit obtained from a 'straight out of service' VC-10.
XL231's original unit is in good condition but a little weak on transmission, so we decided to replace it with a better unit as we had managed to finally obtain a spare.
The unit is the 618T, originally a Marconi badged item but later a Collins unit and it is an extremely powerful item of equipment. Used in many military aircraft, it is one of the few HF radio's that is available. It is also a very bulky and heavy item.

During the Falklands War of 1982 it was this type of HF radio that the AEO in Vulcan XM607 used to contact the UK in order to confirm the successful operation to bomb Port Stanley Airfield.
