  • Notes

  • External VFO with output frequencies: VFO-A: 5.0 ÷ 5.5 MHz, VFO-B: 8.2 ÷ 8.7 MHz,
    VFO-C: 8.9 ÷ 9.4 MHz.
    Output Voltage: 2 V p-p. Output Impedance: 50 ÷ 100 Ω. Frequency display direct read. 
    This VFO may be used also as a Frequency Counter from 10 Hz to 30 MHz with input level     0.1 V (p-p) above 100 kHz and 1 V (p-p) below 100 kHz.
    Three separate outputs for VFO-A, VFO-B and VFO-C.
    The operating voltage is changed by moving the connections directly on the power transformer.

    28 Transistors, 38 ICs and 59 Diodes, listed one per type.
    Only one IC (IS3554) not present in the semiconductor list.
