  • Notes
  • This is an independent device to generate a marker signal every 100 kHz through the radio spectrum. The purpose is to verify and/or calibrate the frequency dial pointer of a radio receiver.

    The device has a trimmer adjustment to allow it to be zero beat to a known frequency standard (like WWV) which then produces an accurate marker across the dial from the harmonics generated from the 100 kHz crystal.

    The range of this device starts at 100 kHz through at least 60 MHz with markers every 100 kHz. No connection to the receiver is necessary, only a loose coupling of the output wire to the antenna of the radio.

    The power switch has two positions to place it in a standby state, and an operating state. The circuit is powered from the 6.3VAC and B+ voltage of a receiver. The size dimensions include the height of the tube.
