Instruction Manual

40 meter band transceiver 7.023 MHZ DIY KIT,Short‐wave radio transmitter receiver

Main indicators

Power supply: 12V (battery or linear regulated power supply is recommended for the)
Antenna: 50 ohms, is not balanced
Transmission power: 3.5W (9V power supply), 5W (12V power supply)
Frequency: launch the vibration frequency, 7023KHZ;Receive this frequency: About 7023‐7026 KHZ
Working pattern: the CW

 Automatic/manual keys

This circuit has the function of automatic identification of automatic and manual keys, as long as the manual button to connect to the mono or referring to the following figure to stereo plug in the middle of the ring and the ground can be together, open the power supply when STC12C4052 SCM according to the inserted key for automatic detection.
Key plug wiring diagram
The key board
SW1: to improve lateral sound frequency
SW2: lower side tone frequency
SW3: automatic launch store number
SW4: improve the rate of fire
SW5: emission reductions
Under normal circumstances, such as no antenna, the headset should be quiet, if found to have low frequency sound, can be between 1 to 2 feet of the NE5532, pick 1only 20p – 471p Ceramics capacitors, to eliminate self‐excited.
