Cobra VHF

I have a new cobra VHF that I can’t transmit calls on. It will receive and when the button is pressed to talk, sound on the radio stops like it is transmitting but it doesn’t. The antenna is new also. Any ideas?

My guess would be the connector that screws into the radio needs a little solder on it,worked wonders on mine.

The connector for the antenna?
Ill check that anyways. Thanks.
