transmission noise

[samuell]

Hi all,i have a noise coming though on transmission on a uhf radio .It sounds a bit like a electric fuel pump tick tick.The radio is abase set mounted in the plane with a switch to go between uhf and vhf.I was wondering about headsets, maybe aerial any other iders would great.cheers Sam

Hmm, just check all the aerial lead connections are clean tight and free off corroision. same goes for headset jack plugs both the male and female. grab some contact cleaner from 'tricky dicks' turn the volume and other knobs and listen for scratchy noise ect if so give the pots a spray.

If it's a specific sort of sound, and doesn't change a great deal, I wouldn't suspect headsets or audio connections - especially if it's in both headsets. Could be a supply related issue, does the display dim or flicker when you transmit?
