51 Super RM Rock Mite QRP CW Transceiver Kit HAM Radio Shortwave Telegraph DIY Unfinished + Shell
Description:
It adopts a 16-pin 12C4052 MCU.
It is added wiht a lot of auxiliary functions, including connection to PC, real-time view of code timing, one-button adjustment of side tone , one-button adjustment of report speed, flexible setting of built-in code.
The 51 version is configured by computer, which is fast and can be set up in a dozen seconds.
Parameters:
- Power Supply: 12V-13.8V (Linear regulated power supply is recommended)
- Antenna: 50Ω, Unbalanced Type
- Transmitting Power: 12V/5W (@12V power supply. The longer the transmitting time, the lower the power will be. D882 as output.)
- Frequency: 7023KHz for transmitting local oscillator frequency. About 7023-7026KHz for receiving local oscillator frequency
- Operating Mode: CW
Use:
Because this machine is the direct conversion transceiver, anti-interference, selectivity can not be compared and the super heterodyne receiver, it is necessary to use not worse than the length of a half-wave dipole antenna, General Conditions communication distance about 500 km security, greater distance depends on the propagation environment and the operating skills of the operator.
Case:
PCB board fits 83x33x110mm aluminum alloy case.
Configuration Software:
Through the RS232 serial port and a PC connected to the online configuration codes speed of sound frequency, maximum working hours, serial tips to keep time.
Automatic transmission code, and use the keyboard instead of key input.
Key Functions:
- K5: automatic transmission storage number
- K4: to improve the side tone frequency
- K3: reduce the side tone frequency
- K2: increase the transmission speed
- K1: reduce the rate of fire
Package Included:
- 1 x CW Transceiver Kit Unfinished + Case
Note:
- It is unfinished and assembling is needed.
- MOS FET 2N7000 in the kit is the last component to be soldered. In order to prevent electrostatic breakdown, please soldering iron power supply should be disconnected and the remaining heat should be used for soldering.
- Certain electronic knowledge is needed for soldering the kit.
