Does a base station go through a transformer?

For a base station that operates from an AC wall outlet and is transistor based; the vast majority of the time the AC wall current is brought into the radio and does go through a transformer, unless the radio uses a switching supply. However, after the transformer the stepped down AC (still AC) is rectified to DC.

How does a DC power supply work?

A DC power supply works by having its chassis connected to the negative side of the output. It also connects the chassis to the safety ground pin of the electrical outlet, which is typically the green wire in the US and the green-and-yellow striped wire in Europe.

Does the power supply have a ground connection?

The power supply of a modern radio apparently has a ground connection, even though it uses a standard AC 3rd prong ground power cable. The radio is fed by the 13.8V DC connector, which does not have an earth.

Is a mobile radio better than a base station Radio?

I currently am using a Galaxy DX 88HL mobile for my base station radio on a power supply. What some may not know is that a typical mobile transceiver will generally hear better than a base radio. Most base radio operates with AC current through a transformer down to unregulated 13.8 DC volts. Most electronic operate more efficiently on DC current.

How many volts does a base radio use?

Most base radio operates with AC current through a transformer down to unregulated 13.8 DC volts. Most electronic operate more efficiently on DC current. With a quality power supply with a variable output, a mobile radio can operate safely at 14 to 14.5 volts. My base CB is a Uniden PC-122 mobile.

Is a power supply safe when not grounded?

A power supply can be considered safe because if a live wire comes in contact with the chassis, the protection circuit, often a fuse, should blow, avoiding any risk of electrocution.
