V2N06WPocket Weather Receiver

Model: TF-6W Circuit Description The Weather Radio device can be receiving Weather broadcasting. Weather radio broadcasting signal via the weather RF amplifier circuitry. Then the GP214D control by CPU (JX903D) to carry on the phase lock loop for stable the oscillator. After the MC3361 is frequency conversion and demodulation, the AF signal outputs to the MC34119 AF amplifier, then output to loudspeaker.
