My VHF radio has good reception, but weak transmission (based on multiple radio checks with our local marine rescue). I checked the pl-259 connector with a multimeter and discovered there is a short between the inner pin and outer connector. Question 1 - is this likely to be the cause of the weak transmission?
Thinking it must be a bad solder job within the pl-259 connector, I decided to replace it with a new one. However, on removal of the plug I discovered the short is still there (zero resistance between the shielding and inner wire). Any suggestions on locating the short (most likely spot)? I was thinking a trip up the mast to check the antenna is probably the best option but I don't really know what to look for. Any advice would be appreciated.
