That picture was taken by Ash who commented above but there's other members on the forum who were there on the day and saw these handsets aswell so they must use them and there really secure radio's so could be if they want there privacy when on fireground but i'm not sure obviously

What radios are they? A station near me (Marsden) keep a set of Motos for a tunnel nearby, if they is an incident at the tunnel they have to use these motos they have, asume its down to them not having signal on the regular firegrounds. The Motos stay at the station when not in use rather than on the appliance.
Ps well done with the photo Moj

Edit.
Just been informed Manchester FRS have the same Moto set as the tunnel runs to Manchester from Huddersfield so if it was MFRS where you had seen these they could be the same ones.
