However I discovered that taking my gloves off and unzipping my jacket pocket to answer my mates calls every 5 minutes can get quite frustrating, and cold. Especially when it turns out not to be my mate but some random talking to his mates on the same channel.
Anyway, long story short, I decided to install a headphone socket so I can hear and respond to my mates without having to remove the radio from my pocket.
Step 1: Crack it open. (Not literally).
If you havent got an old PCI modem to destroy you can buy the sockets from Maplin(79p). I'm sure you guys across the pond can pick them up from RadioShack, and DickSmiths if you're Down Under.
Anyway on with the show. Find the screws, mine were under the battery cover and unscrew them. Put them somewhere safe, I know what you're like!
Gently pull the casing away from the electronics being careful not to rip the wires from the loudspeaker.
