PIC Version 4W Super RM CW Transceiver Shortwave Radio Module Aassembly Board Kit CW Working Modes

Features: Using original RM PIC12F629 microcontroller for manual/automatic key control, has functions such as automatic sending call signs, control sending and receiving indicator LEDs, and is very convenient and practical. When using the auto key, the microcontroller can adjust the codes speed and sidetones frequency, input call signs on its own, and support power-off saving. Using quality operational amplifiers for secondary audioed active filtering greatly improves the listen performances Super RM with extremely low background noise and excellent amplitudes frequency characteristics. The power has been increased to 4W (D882 output), and the kit uses two magnetic rings (FT37-43 and T37-2) each, giving the Super RM strong remote communication capabilities and greatly improving practicality! The transmission frequency is 7.023MHz, and the reception frequency is adjustable from 7.023 to 7.026MHz. A new frequency fset control circuit with 2N7000 is used to improve pat frequency sound quality and listen performances.
