This machine is a simple direct conversion transceiver interference, which means that it requires a 50 ohm, unbalanced antenna not less than the length of a half-wave dipole antenna for effective communication. The selection disturbance is relatively small, making it perfect for communication experiments, but it is best to make an appointment with your friend for communication to reduce the effects of broadcast interference. Communication distance is about 150-300 km, depending on the propagation environment and the operator's operating skills. The BNC CW Transceiver Receiver 7.023KHz Radio Station Frog Sounds HAM Radio Kit is a QRP Kit Telegraph CW Transceiver Receiver Radio Station V3 designed for amateur radio enthusiasts. This small volume kit is powered by a 9V square battery or external 9-12V DC power supply, and can communicate hundreds of kilometers away. The transmission power ranges from 2W to 3W, depending on the power supply, and the frequency is local oscillator frequency: 7023 KHz for the transmitter and about 7023-7026 KHz for the receiver. To improve performance, you can replace the 1N4001 with an appropriate varactor tube to increase the receive frequency range. You can also choose between Q1 9018 power between 0.8W ~ 1.2W and 8050 power between 1.5W to 2W (selecting 8050 will make D882 in a critical state, so you need to be careful). The kit comes with the Frog Sounds HAM Radio QRP Kit Telegraph CW Transceiver Receiver Radio Station V3.
