VCO-Block for CB-Radio


The VCO-Block is a part of the active oscillator in TA7310P. This will opeate between 16MHz and 19MHz.

Output from TA7310P Pin 9 to PLL02A is: Mixer frequency - VCO frequency.
Output from TA7310P Pin 6 to Receiver/Transmitter Mixer is: Mixer frequency + VCO frequency.


The new "VCO-BLOCK" will operate between 14MHz and 21MHz, and will then cover 10-meter, 11-meter and 12-meter.
