Because it seems to work better when you pull the antenna out, and you have (presumably correctly) replaced the end connector, I suspect that there may be a cold-solder joint *inside* the radio. I would also suspect that, because you had a bad antenna connection, you may have blown the transitter amplifier.
I would take the radio to a repair center.
