Why do I need a regulated power supply if I have the radio connected to my 12 volts battery? Wouldn’t it be more easier to disconnect the 12 volts battery. Connected after pressing the mic ptt and power on button and then connect the battery. Will this work?
As the battery power decreases, the voltage may become unstable. So usually if you want to use a mobile radio at home, it is better to get a power supply if possbile, if you use the mobile radio in car, it is also very easy to connect with your car supply
