The Collins DL-1 Dummy Load is a 100 watt resistive
load which can be used for various tuning functions without putting the transmitter
on the air.  The DL-1 can be switched in and out of the circuit by a
front panel switch or can be remotely controlled by the addition of another
switch in the operating position.  This unit reduces tune-up and testing
QRM and requires no connecting or disconnecting of wires prior to operation.
 Weight is 2 lbs. 14 oz.
