Your SWR meter can be calibrated while you have your transmitter keyed and attached to this 3:1 dummy load.

WebThis calculator uses the following formulas for converting the values between the VSWR, return loss, reflection coefficient, and mismatch loss. If VSWR is known, then the reflection coefficient (Γ), return loss (RL), and mismatch loss (ML) is calculated by using following formulas. If the reflection coefficient (Γ) is known, then the VSWR ... SWR is used as a measure of impedance matching of a load to the characteristic impedance of a transmission line carrying radio frequency (RF) signals. This especially applies to transmission lines connecting radio transmitters and receivers with their antennas, as well as similar uses of RF cables such as cable television connections to TV receivers and distribution amplifiers. Impedance matching is achieved when the source impedance is the complex conjugate of the load impedanc…
