  Connecting the RD500 

a.  Power supply.  

The RD500 is designed to operate from a 12V-14V power supply or vehicle battery. 

The power supply lead should be inserted into the rear connector labelled 13.8V the 

centre connector is positive with respect to ground. A vehicle power lead should be 

fused at 1 amp (slow blow), if a larger fuse type is used fault conditions may damage 

the receiver’s circuit board fusable link. The mains power supply is designed to be 

plugged into a 230V 13A mains socket, or 120V outlet if sold in the USA. Power 

consumption is approx. 8W. The maximum current available via the PC keyboard or 

cassette socket is 100mA, this should not be exceeded.   

b.  Antenna connection. 

For long, medium and shortwave use, almost any length of wire or whip aerial can be 

used with the RD500. Short aerials (less than 5 metres) can be connected to the whip 

antenna input and an aerial tuner unit may be useful to get the most out of a random 

length of wire. At VHF and UHF, discone type aerials can offer good results, even 2
