Description: Kit Ultimate V3 Version Ham Radio Qrp Telegraph Cw Transceiver Telegraph1128 Power supply: DC 9V-14VAntenna: 50 ohm, unbalancedReceive quiescent current: 12mA 9VTransmitting power: 12V/3W, 9V/2WFrequency range: transmitting local oscillator 7.023MHz, receiving local oscillator 7.023-7.026MHz (7.023MHz crystal oscillator)Working mode: CWCircuit principleThe core of the receiving part is a NE602. After the signal from the antenna passes through a and an attenuation potentiometer, it enters the mixer. The oscillation circuit oscillates at the receiving frequency. After the two signals are mixed, they are reported directly to SSB/ The CW signal is converted into audio frequency, and the audio output by NE602 is then sent to LM386 for amplification, thus completing the whole process. Therefore, a receiver that directly mixes RF signals into audio is called a ""DC receiver"".The transmitting part uses the oscillation circuit of NE602, and then uses 9018 as buffer amplification. 9018 also serves as the transmitting key to control the switching of the transceiver circuit and signal. The final stage is a Class C amplifier composed of D882. The amplified high-frequency signal passes through the LPF After filtering, connect the antenna.Colour:Photo ColorMaterial:ABSPackage Contents:1 set x frog kit (delivered in parts, without shell)
