Hi all... I have a navman VHF radio, i was out on saturday and had no problems hearing everyone elses conversations,i was off jervis bay n was hearing wollongong, i also was able to talk to boats at close range IE 5 miles but was later told it was very scratchy n i was hard to understand, other boats that i tried to contact (even though i could hear there transmissions to other boats perfectly clear, and could hear them calling for me)later told me they hadnt heard me all day, so i think im receiving transmissions with no problems but im transmitting out very poorly, ive gone over all the wiring and its in good order the exterior of the aerial looks good but cant be certain if theres any damage internally.... anyone got any suggestions?
