The DL-1 is a 100-watt resistor load for use with any 100-watt transmitter or transceiver such as the 32S-1, 32S-3, or KWM-2. Refer to figure 1. Use of this dummy load allows alignment or adjustment of transmitter circuits without sustained radiation of an interfering carrier. The DL-1 consists of four 50-ohm Globar resistors in a series-parallel arrangement to provide a 50-ohm resistive load. The DL-1 may be switched locally or remotely to select antenna or dummy load for connection to transmitter output. Jacks are provided for 6.3-volt ac 50- to 60-Hz relay coil supply, remote switching, and transmitter and antenna connections. The unit can be set on a table or desk or mounted on any chassis or rack frame by means of the two tapped holes on the bottom. As an alternate mounting, the four rubber feet can be removed and the unit mounted on a flat plate with four 6-32 screws.
