67project team shares very good quality posts about sdr in the “Radio frequency-Radio amateurism” section, they share their work on this subject with their resources, and there are also information about sites where information about sdr applications are available. Thank you to the people who contributed.
As the name suggests, Software Defined Radio is a radio technology that performs most of the radio functions by using software instead of using resistors, capacitors, and feedback circuits to process the radio signal, and it is defined as a radio communication system that uses software for both modulation and demodulation of signals.

Adjustable Laboratory Power Supply Circuit 37V 3A
a power supply based on LM723 ST makes it at 40V input voltage 1-37V and 40mA-3A, the voltage is a controller for fine-tuning available. Voltage current Adjustable Power Source circuit lm723 voltage regulator IC based on the used power transistors 2 bd249 input voltage dc 40 volts dc 1v 37volt voltages setting 40 mA 3 amps current setting, there is also the current settings for the two dials used this way, precise adjustments can be made
A separate floor as part of the circuit can be regulated or PCBs can edit the file kbu808 bridge for rectification diodes used 4 or 6 amp filter capacitor 10000uF
