This machine was first introduced by domestic radio enthusiasts, but also it played a nice name"frogs" The frogs calling Kit 3.1 public version based combined with the actual usage Fixed several key issues, after several debugging before the formation of the current version. Key Indicators Power supply: 9V-12V(Recommended 12V linear regulated power supply) Antenna: 50 ohm. Unbalanced Transmission power: 2W(9V Power) 3W(12V power) Frequency: transmitter local oscillator frequency: 7023 KHz; receive local oscillator frequency: about 7023-7026 KHz Operating mode: CW Use This machine is simple direct conversion transceiver interference. Selectivity can be compared and the super heterodyne receiver, it is necessary to use not worse than the length of a half-wave dipole antenna, or communication is relatively poor. The selection disturbance is relatively small; spread the good opportunity for communication experiment, it is best to make an appointment with your friend’s communication. Communication distance of about 150-300 km more secure, to greater distance depends on the propagation environment and the operator's operating skills.
