you'll need a filter capacitor in the power line to the radio. wiring varies according the the individual unit, but typically one side to power, the other to ground.
Try resetting the radio per the user manual by doing a setup procedure as described on page 28. This may clear up the problem. User manual here: https://www.cobra.com/sites/default/files/manuals/MRF75D%20-%20ENGLISH_0.pdf
Check your microphone by swapping with another duplicate. If no differance, you will need a SWR meter (standing wave ratio) to find the culprit. It attaches in line of the coax and determinds power out and reflected power. The reading should be 25 watts foward and max of 1 reflected.
