Power supply from mains - All broadcast equipment (transmitter,
computer, mixing console) should be supplied from one mains-socket outlet and should have
galvanically connected all grounds. Then in 99.9 % cases you will not have any
problems with ground loops.
Transmitter's power supply - Power supply must have noise suppressed
all semiconductor parts (diodes, stabilizer)! Use 4.7 nF capacitors and interconnect all
Broadcasting antenna - Don't broadcast with wire or mast aerial! Use
only reccomended types of antenna!
