1PC CW Transceiver Module Shortwave Radio 7023kHz 5W Automatic Key Speed Adjustable Upper Computer Control HAM DIY Parts leírása

Working mode: CW (equal amplitude telegram) frequency: transmitting 7023kHz crystal error; Receive approximately 7023~7026kHz (adjustable) power supply: 12V~13.8V (recommended linear regulator power supply)
Transmission power: Typical value of 5W at 12V (using D882 output) Antenna impedance: 50 Ω, unbalanced
Side tone: Yes, frequency adjustable (set through buttons) Function buttons: 5 (speed+/-, automatic shooting, function switching, etc.)
Automatic call sign: Support (users can input call signs themselves) Host computer control: Yes (TTL serial port, USB to TTL module needs to be provided)
Kit size: 109mm x 77mm (shell)

Features:
The 51 version adds MCU intelligent control the basis of the original version, supporting automatic call sign sending, code sending speed adjustment, and upper computer software control, adding modern gameplay to the classic CW radio.
Classic receiver circuit: NE602 balanced mixing+NE5532 low-pass filtering/audio amplification, high sensitivity, low noise floor.
When the transmission power is about 5W: 12V power supply, the output is stable. The D882 final amplifier, combined with a 1:4 transformer and low-pass filter, has low harmonics.
Built in automatic key and side tone: 5 function keys that can adjust the code sending speed, store and automatically send call signs (such as CQ CQ DE...).
Upper computer software control: Connected to the computer through a serial port, supports PC control of sending and speed settings, etc. (comes with simple software).
Compact size: The PCB and casing are only 109mm x 77mm, making it easy to carry.
Color: As Shown
Material: PCB
