Notes: 1) When receiver values were given for preamp on/off, the preamp on numbers were used here. 2) When values for more than one HF Amateur band are given, the worst numbers were used. (example: general coverage receiver numbers for 1.0 MHz were not considered, if a rig covers 50MHz, those numbers were not considered.)
