I calibrated the HM-102 on 40 meters as per the instructions. The power output as indicated on the test set was 104 watts - the Heath showed just a hair under 100. I then went to 10 and 160 meters to compare reading again and found the greatest difference at the 100-watt level to be 7 to 8 watts, ie within the 10% spec.
