Re: Qrpometer calibration


Just for the sake of QRPoMeter builders, I have changed the calibration procedure in the past year, so that may be the source of confusion.  And the 4SQRP kits are different from the NM0S kits.

It is normal for the VSWR reading to be something besides zero with no RF applied.  But, the Power reading should be zero.  Check to see that the diodes are inserted in the correct orientation, and that they measure about 0.6v in the forward direction, using the diode checker in your multimeter.

Karen, did you move the decimal set solder short on the back of the meter?
