Faulty Navman 7100

I have a fixed Navman DSC radio on the boat, which to my knowledge has worked very well.
However on the way out of Christchurch on Saturday, it became obvious that whilst it was receiving very well, when I came to make a transmission, there was a short burst of static and then nothing (as reported by another boat).

All other functions appear to be working well, where would you suggest I start?
I am tempted to dismantle the hand mic first.

Thanks Steve

Is it possible to unscrew and swap the mic over?

Is high power selected? (HI) on the set?
Check the aerial connections etc

Re the swap, no the hand mic is hard wired to the set.
The radio normally defaults to High power, though I confess I did not check. The other boat was within about 1/2 mile, so even on low power should have got something.

Will check out the ariel tomorrow, is there a situation where it could receive but not transmit?

Dirty contacts might do that.



Silly question-does your display dim when you transmit?
