Spread good time, and the nearby provinces hundreds of kilometers amateur radio communications. 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. If the broadcast interference is relatively large, use 5K GAIN potentiometer signal attenuation, emergent signal from the radio interference. Attenuation potentiometer is critical, carefully adjusted; you will receive an unexpected effect. In the dissemination of good times with of this machine FT80C goods shortwave radio with a signal on a distant contrast reception, this local effect is no difference between basic commodity machine, which makes unexpected.

$8.50 Shipping Condition: Used Location: Modesto, United States You are bidding on a assembled timer circuit board kit. It operates from 9 to 12 volts DC voltage only and has four push buttons for inputs and a single ... morepole double throw relay and buzzer connected to outputs. There is also a seven segment display driven by two one digit drivers as well as two sets of slide switches. One set for inputs and the other allow the relay or buzzer to be turned off or on. The normally open contact is rated for 20 amps while the normally closed contact is rated for 10 amps. However I recommend half of the rated value 10 amps for the normally open and 5 amps for the normally closed. I will provide sample code segments for the seven segment display. Code to relate the signal input to the relay and buzzer, and code for time in terms of seconds. However this code will be seperate modules so the individual will have to learn how to program the microcontroller. The board will be programmed with only the seven segment code which will make will only make the seven seven segment display operable, the only to buttons that will work will be the two top left hand push buttons which will increase and decrease the display from 0 the 99. The microcontroller this board is designed around is the picaxe 20m2 which is included with the circuit board. Any pic that has the same pin layout and input and output current and voltages can also be used in this circuit board. These are high quality circuit boards with plated through holes and a silk screen. The circuit board has been assembled. Soldered, and tested. All the components have been specified by experienced electrical engineer. The circuit board layout and routing was also done by an experienced electrical engineer. There are several different functions in which this board can be used depending on the creativity and the level of experience of programming an individual has. The completed unit can be used for training purposes or a solid tool. With every board you will receive a circuit schematic. Sample code, fuse holder, 10 amp fuse,spare microcontroll
