|Description:||VFO Variable Frequency Oscillator|
INTRODUCTION The V-10 consists basically of a seven band, electrically, mechanically and thermally stable variable frequency Oscillator to be used in conjunction with CW, AM, or SSB transmitters. It provides a stable output for 160, 80, 40, 20, 15, 10, and 6 meters, covering all portions oi each band. 2. DESIGN Considerable time and effort were spent in the engineering of the V-10 to accomplish the most favorable arrangements of electrical, mechanical, and thermal designs. A modified Clapp Oscillator was chosen because of the series tuned arrangement of the frequency determining circuits, in which case small changes in input capacity of the tube will have little or no effect on frequency. By using electron coupling, frequency variations, due to output loading, were minimized. All frequency determining components have been completely enclosed in a separate compartment to isolate them from drafts and sudden changes in temperature. The remotely controlled band switch was also enclosed in this compartment to provide short leads to the components it controls. A sturdy, two section variable capacitor was used to provide maximum band spread and stability on all bands. Temperature compensation was used liberally to reduce frequency drift during and after warm-up. A cathode follower stage proceeding the Oscillator, isolates the Oscillator from the buffer Amplifier, while the broadband buffer Amplifier provides amplification and also isolation from the Transmitter. Voltage regulation is used in all voltage sensitive circuits. The unit contains its own Power Supply, thereby enabling it to be used with all types of equipment.
