Transmission Line Details - This utility program shows the impedance and reflection coefficient parameters (SWR, reflection coefficient magnitude Rho, or Return Loss RL in dB) at both ends of a transmission line and the details of power loss in the line. It includes built-in specifications for approximately 100 different line types. You can modify the specs to see how small changes affect the results or to specify custom lines. All program inputs may be changed directly or you can use spin buttons to make the changes.

Remote Power and SWR Meter Project - Remotely monitor the output power and SWR of your station via a web browser. WT32/ESP32 based project, combined with a directional coupler setup. It reads two voltages which are supplied by the directional couplers. From these, the respective power is calculated with the help of a calibration data table to be created by the user.
