Thanks for th replys,it may be something simle Im not overly smart with this sort of stuff .No battery ,only in the Verex . Radio is fine until I plug in the lead going to junction box for h/sets etc then nothing ,even if I push the talk button on the radio its self & squelch they don't work until I pull that lead out then fine ,so Im thinking it may be the connection in the top of the Radio or the lead going to Lynx junction box which I could probably test with multimeter if I knew a bit about it ,cheers
