• Put in the rf circuit and provides higher sensitivity 13
• Quency is available on every 10khz 13
• Signals will be fed to the receiver directly 13
• Sound from the speaker causing a switch to transmit this 13
• Such as the wwv 13
• Switches rf preamplifier and attenuator in the rf circuit 13
• The attenuator into the circuit this gives about 20db 13
• The switch in the pre position and the preamplifier is 13
• This removes the preamplifier from the circuit and inserts 13
• Tone when the monitor switch on the front panel is 13
• Trouble can be prevented by adjusting the input level of the 13
• Turned on adjust the control for comfortable monitoring 13
• Turns the marker circuit on or off the marker fre 13
