Tom, That is exactly what I said. In CALP, if the load is anything other than 50+j0, the power indication will be incorrect. In other words, the requested power may not equal the actual power.
When you go to AUTO and do a TUNE, the forward power should be close to the requested power. 73, Don W3FPR Tom Campie wrote: > I calibrated the tuner to a 50 ohm load on CALP.
